    SYNOPSIS

           qsub [-a date_time][-A account_string][-c interval]
                     [-C   directive_prefix][-e   path_name][-h][-j  join_list][-k
           keep_list]
                   [-m mail_options][-M mail_list][-N name]
                   [-o path_name][-p priority][-q destination][-r y|n]

                   [-z][script]
    
    
    

    DESCRIPTION

           To submit a script is to create a batch job that executes  the  script.
           A  script is submitted by a request to a batch server. The qsub utility
           is a user-accessible batch client that submits a script.
    
           Upon successful completion, the qsub utility shall have created a batch
           job that will execute the submitted script.
    
           The  qsub  utility shall submit a script by sending a Queue Job Request
           to a batch server.
    
           The qsub utility shall place the value  of  the  following  environment
           variables  in the Variable_List attribute of the batch job: HOME , LANG
           , LOGNAME , PATH , MAIL , SHELL , and TZ . The name of the  environment
           variable shall be the current name prefixed with the string PBS_O_.
    
           Note:  If  the  current  value  of the HOME variable in the environment
                  space of the qsub utility is /aa/bb/cc, then  qsub  shall  place
                  PBS_O_HOME  =  /aa/bb/cc  in  the Variable_List attribute of the
                  batch job.
    
           In addition to the variables described above, the  qsub  utility  shall
           add  the  following variables with the indicated values to the variable
           list:
    
           PBS_O_WORKDIR
                  The absolute path of the current working directory of  the  qsub
                  utility process.
    
           PBS_O_HOST
                  The name of the host on which the qsub utility is running.
    
    
    

    OPTIONS

           The  qsub  utility  shall  conform  to  the  Base Definitions volume of
           IEEE Std 1003.1-2001, Section 12.2, Utility Syntax Guidelines.
    
           The following options shall be supported by the implementation:
    
           -a  date_time
                  Define the time at which a batch job becomes eligible for execu-
                  tion.
                          PBS_O_SHELL     SHELL
                          PBS_O_TZ        TZ
                          PBS_O_WORKDIR   Current working directory
    
           Note:
                  The server that initiates execution of the batch  job  will  add
                  other  variables  to  the batch job's environment; see Batch Job
                  Execution .
    
           The qsub utility shall set the Execution_Time attribute  of  the  batch
           job  to the number of seconds since the Epoch that is equivalent to the
           local time expressed by the value of the date_time option-argument. The
           Epoch    is    defined    in    the    Base   Definitions   volume   of
           IEEE Std 1003.1-2001, Section 3.149, Epoch.
    
           If the -a option is not presented to  the  qsub  utility,  the  utility
           shall set the Execution_Time attribute of the batch job to a time (num-
           ber of seconds since the Epoch) that is earlier than the time at  which
           the utility exits.
    
           -A  account_string
    
                  Define  the  account  to  which  the resource consumption of the
                  batch job should be charged.
    
           The syntax of the account_string option-argument is unspecified.
    
           The qsub utility shall set the Account_Name attribute of the batch  job
           to the value of the account_string option-argument.
    
           If  the  -A  option  is  not presented to the qsub utility, the utility
           shall omit the Account_Name attribute from the attributes of the  batch
           job.
    
           -c  interval
                  Define  whether the batch job should be checkpointed, and if so,
                  how often.
    
           The qsub utility shall accept a value for the interval  option-argument
           that is one of the following:
    
           n
                  No  checkpointing shall be performed on the batch job (NO_CHECK-
                  POINT).
    
           s
                  Checkpointing shall be performed only when the batch  server  is
                  shut down (CHECKPOINT_AT_SHUTDOWN).
    
           c
                  Automatic periodic checkpointing shall be performed at the Mini-
    
           shall set the Checkpoint attribute of the batch job to the single char-
           acter 'u' (CHECKPOINT_UNSPECIFIED).
    
           -C  directive_prefix
    
                  Define  the prefix that declares a directive to the qsub utility
                  within the script.
    
           The directive_prefix is not a  batch  job  attribute;  it  affects  the
           behavior of the qsub utility.
    
           If the -C option is presented to the qsub utility, and the value of the
           directive_prefix option-argument is the null string, the utility  shall
           not  scan the script file for directives.  If the -C option is not pre-
           sented to the qsub utility, then the value of the PBS_DPREFIX  environ-
           ment variable is used. If the environment variable is not defined, then
           #PBS encoded in the portable character set is the default.
    
           -e  path_name
                  Define the path to be used for the standard error stream of  the
                  batch job.
    
           The  qsub utility shall accept a path_name option-argument which can be
           preceded by a host name element of the form hostname:.
    
           If the path_name option-argument constitutes an absolute pathname,  the
           qsub utility shall set the Error_Path attribute of the batch job to the
           value of the path_name option-argument.
    
           If the path_name option-argument constitutes a relative pathname and no
           host  name  element  is  specified,  the  qsub  utility  shall  set the
           Error_Path attribute of the batch job to  the  value  of  the  absolute
           pathname derived by expanding the path_name option-argument relative to
           the current directory of the process executing qsub.
    
           If the path_name option-argument constitutes a relative pathname and  a
           host  name  element  is  specified,  the  qsub  utility  shall  set the
           Error_Path attribute of the batch job to the  value  of  the  path_name
           option-argument  without  expansion.  The  host  name  element shall be
           included.
    
           If the path_name option-argument does not include a host name  element,
           the  qsub utility shall prefix the pathname with hostname:, where host-
           name is the name of the host upon which the qsub utility is being  exe-
           cuted.
    
           If  the  -e  option  is  not presented to the qsub utility, the utility
           shall set the Error_Path attribute of the batch job to  the  host  name
           and  path  of  the  current directory of the submitting process and the
           default filename.
    
           The default filename for standard error has the following format:
                  Define which streams of the batch job are to be merged. The qsub
                  -j option shall accept a value for the join_list option-argument
                  that  is  a  string  of  alphanumeric characters in the portable
                  character   set   (see   the   Base   Definitions   volume    of
                  IEEE Std 1003.1-2001, Section 6.1, Portable Character Set).
    
           The qsub utility shall accept a join_list option-argument that consists
           of one or more of the characters 'e' and 'o' , or the single  character
           'n' .
    
           All of the other batch job output streams specified will be merged into
           the output stream represented by the  character  listed  first  in  the
           join_list option-argument.
    
           For  each  unique  character in the join_list option-argument, the qsub
           utility shall add a value to the Join_Path attribute of the  batch  job
           as follows, each representing a different batch job stream to join:
    
           e
                  The standard error of the batch job (JOIN_STD_ERROR).
    
           o
                  The standard output of the batch job (JOIN_STD_OUTPUT).
    
           An  existing  Join_Path  attribute can be cleared by the following join
           type:
    
           n
                  NO_JOIN
    
           If 'n' is specified, then no files are joined. The qsub  utility  shall
           consider  it  an error if any join type other than 'n' is combined with
           join type 'n' .
    
           Strictly conforming applications shall not repeat any of the characters
           'e' , 'o' , or 'n' within the join_list option-argument. The qsub util-
           ity shall permit the repetition of characters,  but  shall  not  assign
           additional meaning to the repeated characters.
    
           An implementation may define other join types. The conformance document
           for an implementation shall describe any additional batch job  streams,
           how  they  are  specified, their internal behavior, and how they affect
           the behavior of the utility.
    
           If the -j option is not presented to  the  qsub  utility,  the  utility
           shall  set  the  value  of  the Join_Path attribute of the batch job to
           NO_JOIN.
    
           -k  keep_list
                  Define which output of the batch job to retain on the  execution
    
           e
                  The standard error of the batch job (KEEP_STD_ERROR).
    
           o
                  The standard output of the batch job (KEEP_STD_OUTPUT).
    
           If both 'e' and 'o' are specified, then both  files  are  retained.  An
           existing  Keep_Files  attribute  can  be  cleared by the following keep
           type:
    
           n
                  NO_KEEP
    
           If 'n' is specified, then no files are retained. The qsub utility shall
           consider  it  an error if any keep type other than 'n' is combined with
           keep type 'n' .
    
           Strictly conforming applications shall not repeat any of the characters
           'e' , 'o' , or 'n' within the keep_list option-argument. The qsub util-
           ity shall permit the repetition of characters,  but  shall  not  assign
           additional meaning to the repeated characters.
    
           An implementation may define other keep types. The conformance document
           for an implementation shall describe any  additional  keep  types,  how
           they  are  specified,  their internal behavior, and how they affect the
           behavior of the utility. If the -k option is not presented to the  qsub
           utility,  the  utility  shall set the Keep_Files attribute of the batch
           job to the value NO_KEEP.
    
           -m  mail_options
    
                  Define the points in the execution of the batch job at which the
                  batch  server that manages the batch job shall send mail about a
                  change in the state of the batch job.
    
           The qsub -m option shall accept a value for  the  mail_options  option-
           argument  that  is  a string of alphanumeric characters in the portable
           character set (see the Base Definitions volume of IEEE Std 1003.1-2001,
           Section 6.1, Portable Character Set).
    
           The qsub utility shall accept a value for the mail_options option-argu-
           ment that is a string of one or more of the characters 'e' , 'b' ,  and
           'a' , or the single character 'n' .
    
           For each unique character in the mail_options option-argument, the qsub
           utility shall add a value to the Mail_Users attribute of the batch  job
           as  follows,  each  representing  a different time during the life of a
           batch job at which to send mail:
    
           type:
    
           n
                  NO_MAIL
    
           If 'n' is specified, then mail is not sent. The qsub utility shall con-
           sider it an error if any mail type other than 'n' is combined with mail
           type 'n' .
    
           Strictly conforming applications shall not repeat any of the characters
           'e' , 'b' , 'a' , or 'n' within the mail_options option-argument.
    
           The  qsub  utility shall permit the repetition of characters, but shall
           not assign additional meaning to the repeated characters. An  implemen-
           tation  may  define  other  mail types. The conformance document for an
           implementation shall describe any additional mail types, how  they  are
           specified, their internal behavior, and how they affect the behavior of
           the utility.
    
           If the -m option is not presented to  the  qsub  utility,  the  utility
           shall set the Mail_Points attribute to the value MAIL_AT_ABORT.
    
           -M  mail_list
                  Define  the  list of users to which a batch server that executes
                  the batch job shall send mail, if the server  sends  mail  about
                  the batch job.
    
           The syntax of the mail_list option-argument is unspecified.
    
           If the implementation of the qsub utility uses a name service to locate
           users, the utility should accept the syntax used by the name service.
    
           If the implementation of the qsub utility does not use a  name  service
           to  locate users, the implementation should accept the following syntax
           for user names:
    
                  mail_address[,,mail_address,, ...]
    
           The interpretation of mail_address is implementation-defined.
    
           The qsub utility shall set the Mail_Users attribute of the batch job to
           the value of the mail_list option-argument.
    
           If  the  -M  option  is  not presented to the qsub utility, the utility
           shall place only the user name and host name for the current process in
           the Mail_Users attribute of the batch job.
    
           -N  name
                  Define the name of the batch job.
    
           If  the  -N option is not presented to the qsub utility, and the script
           is read from  standard  input,  the  utility  shall  set  the  Job_Name
           attribute of the batch job to the value STDIN.
    
           -o  path_name
                  Define the path for the standard output of the batch job.
    
           The qsub utility shall accept a path_name option-argument that conforms
           to the syntax of the path_name element defined in the System Interfaces
           volume  of  IEEE Std 1003.1-2001,  which can be preceded by a host name
           element of the form hostname:.
    
           If the path_name option-argument constitutes an absolute pathname,  the
           qsub  utility  shall  set the Output_Path attribute of the batch job to
           the value of the path_name option-argument without expansion.
    
           If the path_name option-argument constitutes a relative pathname and no
           host  name  element  is  specified, the qsub utility shall set the Out-
           put_Path attribute of the batch job to the pathname derived by  expand-
           ing  the value of the path_name option-argument relative to the current
           directory of the process executing the qsub.
    
           If the path_name option-argument constitutes a relative pathname and  a
           host  name  element  is  specified, the qsub utility shall set the Out-
           put_Path attribute of the batch job  to  the  value  of  the  path_name
           option-argument without expansion.
    
           If  the path_name option-argument does not specify a host name element,
           the qsub utility shall prefix the pathname with hostname:, where  host-
           name  is the name of the host upon which the qsub utility is executing.
    
           If the -o option is not presented to  the  qsub  utility,  the  utility
           shall  set  the Output_Path attribute of the batch job to the host name
           and path of the current directory of the  submitting  process  and  the
           default filename.
    
           The default filename for standard output has the following format:
    
                  job_name.osequence_number
    
           -p  priority
                  Define  the priority the batch job should have relative to other
                  batch jobs owned by the batch server.
    
           The qsub utility shall set the Priority attribute of the batch  job  to
           the value of the priority option-argument.
    
           If the -p option is not presented to the qsub utility, the value of the
           Priority attribute is implementation-defined.
    
           The qsub utility shall accept a value for the priority  option-argument
    
           The qsub utility shall accept an option-argument for the -q option that
           conforms to the syntax for a destination (see Destination ).
    
           If the -q option is not presented to the qsub utility, the qsub utility
           shall submit the batch job to the default  destination.  The  mechanism
           for determining the default destination is implementation-defined.
    
           -r  y|n
                  Define whether the batch job is rerunnable.
    
           If  the  value  of the option-argument is y, the qsub utility shall set
           the Rerunable attribute of the batch job to TRUE.
    
           If the value of the option-argument is n, the qsub  utility  shall  set
           the Rerunable attribute of the batch job to FALSE.
    
           If  the  -r  option  is  not presented to the qsub utility, the utility
           shall set the Rerunable attribute of the batch job to TRUE.
    
           -S  path_name_list
    
                  Define the pathname to the shell under which the batch job is to
                  execute.
    
           The  qsub  utility  shall  accept a path_name_list option-argument that
           conforms to the following syntax:
    
                  pathname[@host][,,pathname[@host],, ...]
    
           The qsub utility shall allow only one pathname for a given  host  name.
           The qsub utility shall allow only one pathname that is missing a corre-
           sponding host name.
    
           The qsub utility shall add a value to the Shell_Path_List attribute  of
           the batch job for each entry in the path_name_list option-argument.
    
           If  the  -S  option  is  not presented to the qsub utility, the utility
           shall set the Shell_Path_List attribute of the batch job  to  the  null
           string.
    
           The conformance document for an implementation shall describe the mech-
           anism used to set the default shell and determine the current value  of
           the  default  shell.  An  implementation  shall provide a means for the
           installation to set the default shell to the login shell  of  the  user
           under  which  the  batch  job is to execute. See Multiple Keyword-Value
           Pairs for a means of removing keyword= value (and value@ keyword) pairs
           and other general rules for list-oriented batch job attributes.
    
           -u  user_list
                  Define the user name under which the batch job is to execute.
    
           If  the  -u  option  is  not presented to the qsub utility, the utility
           shall set the User_List attribute of the batch job  to  the  user  name
           from  which  the utility is executing. See Multiple Keyword-Value Pairs
           for a means of removing keyword= value (and value@ keyword)  pairs  and
           other general rules for list-oriented batch job attributes.
    
           -v  variable_list
    
                  Add  to  the  list of variables that are exported to the session
                  leader of the batch job.
    
           A variable_list is a set of strings of either the form < variable> or <
           variable= value>, delimited by commas.
    
           If  the  -v  option is presented to the qsub utility, the utility shall
           also add, to the environment Variable_List attribute of the batch  job,
           every  variable  named in the environment variable_list option-argument
           and, optionally, values of specified variables.
    
           If a value is not provided on the command line, the qsub utility  shall
           set  the  value  of  each  variable  in  the  environment Variable_List
           attribute of the batch job to the value of the  corresponding  environ-
           ment  variable  for  the process in which the utility is executing; see
           Environment Variable Values (Utilities) .
    
           A conforming application shall not repeat a variable in the environment
           variable_list option-argument.
    
           The  qsub  utility shall not repeat a variable in the environment Vari-
           able_List attribute of the batch job. See Multiple Keyword-Value  Pairs
           for  a  means of removing keyword= value (and value@ keyword) pairs and
           other general rules for list-oriented batch job attributes.
    
           -V     Specify that all of the environment variables of the process are
                  exported to the context of the batch job.
    
           The  qsub utility shall place every environment variable in the process
           in which the utility is executing in the list and shall set  the  value
           of  each variable in the attribute to the value of that variable in the
           process.
    
           -z     Specify that the utility does not write the batch job_identifier
                  of the created batch job to standard output.
    
           If  the  -z  option is presented to the qsub utility, the utility shall
           not write the batch job_identifier of the created batch job to standard
           output.
    
           If  the  -z  option  is  not presented to the qsub utility, the utility
           shall write the identifier of the created batch job to standard output.
    
           if the script operand is omitted or is the single character '-' .
    
    
    

    INPUT FILES

           In  addition to binding the file indicated by the script operand to the
           batch job, the qsub utility reads the script file and  acts  on  direc-
           tives in the script.
    
    
    

    ENVIRONMENT VARIABLES

           The following environment variables shall affect the execution of qsub:
    
           LANG   Provide a default value for the  internationalization  variables
                  that  are  unset  or  null.  (See the Base Definitions volume of
                  IEEE Std 1003.1-2001, Section  8.2,  Internationalization  Vari-
                  ables  for the precedence of internationalization variables used
                  to determine the values of locale categories.)
    
           LC_ALL If set to a non-empty string value, override the values  of  all
                  the other internationalization variables.
    
           LC_CTYPE
                  Determine  the  locale  for  the  interpretation of sequences of
                  bytes of text data as characters (for  example,  single-byte  as
                  opposed to multi-byte characters in arguments).
    
           LC_MESSAGES
                  Determine  the  locale  that should be used to affect the format
                  and contents of diagnostic messages written to standard error.
    
           LOGNAME
                  Determine the login name of the user.
    
           PBS_DPREFIX
    
                  Determine the default prefix for directives within the script.
    
           SHELL  Determine the pathname of the preferred command language  inter-
                  preter of the user.
    
           TZ     Determine  the  timezone used to interpret the date-time option-
                  argument.  If TZ is unset or null, an unspecified default  time-
                  zone shall be used.
    
    
    

    ASYNCHRONOUS EVENTS

           Once created, a batch job exists until it exits, aborts, or is deleted.
    
           After a batch job is created by the qsub utility, batch  servers  might
           route, execute, modify, or delete the batch job.
    
    
    

    STDOUT

           The  qsub utility writes the batch job_identifier assigned to the batch
           job to standard output, unless the -z option is specified.
           Queue Job Request or store a temporary copy of the script in a location
           specified to the server.
    
       Option Specification
           A script can contain directives to the qsub utility.
    
           The qsub utility shall scan the lines of  the  script  for  directives,
           skipping  blank  lines,  until the first line that begins with a string
           other than the directive string;  if  directives  occur  on  subsequent
           lines, the utility shall ignore those directives.
    
           Lines  are  separated  by  a <newline>. If the first line of the script
           begins with "#!" or a colon ( ':' ), then it is skipped. The qsub util-
           ity  shall  process  a line in the script as a directive if and only if
           the string of characters from the first  non-white-space  character  on
           the  line until the first <space> or <tab> on the line match the direc-
           tive prefix. If a line in the script contains a directive and the final
           characters  of  the  line are backslash ( '\' ) and <newline>, then the
           next line shall be interpreted as a continuation of that directive.
    
           The qsub utility shall process the options  and  option-arguments  con-
           tained  on  the  directive  prefix line using the same syntax as if the
           options were input on the qsub utility.
    
           The qsub utility shall continue to  process  a  directive  prefix  line
           until  after  a  <newline> is encountered. An implementation may ignore
           lines which, according to the syntax of the shell that  will  interpret
           the  script, are comments. An implementation shall describe in the con-
           formance document the format of any shell comments that it will  recog-
           nize.
    
           If  an  option  is present in both a directive and the arguments to the
           qsub utility, the utility shall ignore the option and the corresponding
           option-argument, if any, in the directive.
    
           If  an  option  that  is present in the directive is not present in the
           arguments to the qsub utility, the utility shall process the option and
           the option-argument, if any.
    
           In  order  of  preference,  the qsub utility shall select the directive
           prefix from one of the following sources:
    
            * If the -C option is presented to  the  utility,  the  value  of  the
              directive_prefix option-argument
    
            * If  the  environment  variable  PBS_DPREFIX is defined, the value of
              that variable
    
            * The four-character string "#PBS" encoded in the  portable  character
              set

    RATIONALE

           The  qsub  utility allows users to create a batch job that will process
           the script specified as the operand of the utility.
    
           The options of the qsub utility allow users to control many aspects  of
           the queuing and execution of a batch job.
    
           The  -a option allows users to designate the time after which the batch
           job will become eligible to run. By specifying an execution time, users
           can  take  advantage  of  resources at off-peak hours, synchronize jobs
           with chronologically predictable events, and perhaps take advantage  of
           off-peak  pricing  of  computing time.  For these reasons and others, a
           timing option is existing practice on the part of  almost  every  batch
           system, including NQS.
    
           The  -A option allows users to specify the account that will be charged
           for the batch job. Support for account is not mandatory for  conforming
           batch servers.
    
           The  -C  option  allows  users  to  prescribe the prefix for directives
           within the script file. The default prefix "#PBS" may be  inappropriate
           if the script will be interpreted with an alternate shell, as specified
           by the -S option.
    
           The -c option allows users to establish the checkpointing interval  for
           their jobs. A checkpointing system, which is not defined by this volume
           of IEEE Std 1003.1-2001, allows recovery of a batch  job  at  the  most
           recent  checkpoint  in the event of a crash. Checkpointing is typically
           used for jobs that consume expensive computing  time  or  must  meet  a
           critical schedule. Users should be allowed to make the tradeoff between
           the overhead of checkpointing and the risk to the timely completion  of
           the  batch job; therefore, this volume of IEEE Std 1003.1-2001 provides
           the  checkpointing  interval  option.  Support  for  checkpointing   is
           optional for batch servers.
    
           The  -e  option  allows users to redirect the standard error streams of
           their jobs to a non-default path. For example, if the submitted  script
           generally  produces  a great deal of useless error output, a user might
           redirect the standard error output to the null device. Or, if the  file
           system  holding  the  default location (the home directory of the user)
           has too little free space, the user might redirect the  standard  error
           stream to a file in another file system.
    
           or other designated users, can track the progress of a batch job.
    
           The  -N option allows users to associate a name with the batch job. The
           job name in no way affects the processing of the batch job, but  rather
           serves  as a mnemonic handle for users. For example, the batch job name
           can help the user distinguish between multiple jobs listed by the qstat
           utility.
    
           The  -o  option allows users to redirect the standard output stream.  A
           user might, for example, wish to redirect to the null device the  stan-
           dard  output stream of a job that produces copious yet superfluous out-
           put.
    
           The -P option allows users to designate  the  relative  priority  of  a
           batch job for selection from a queue.
    
           The  -q  option  allows users to specify an initial queue for the batch
           job. If the user specifies a routing queue, the batch server routes the
           batch  job  to  another  queue for execution or further routing. If the
           user specifies a non-routing queue, the batch server of the queue even-
           tually executes the batch job.
    
           The -r option allows users to control whether the submitted job will be
           rerun if the controlling batch node fails during execution of the batch
           job. The -r option likewise allows users to indicate whether or not the
           batch job is eligible to be rerun by the qrerun utility. Some jobs can-
           not  be  correctly  rerun  because of changes they make in the state of
           databases or other  aspects  of  their  environment.   This  volume  of
           IEEE Std 1003.1-2001  specifies  that  the default, if the -r option is
           not presented to the utility, will be that  the  batch  job  cannot  be
           rerun,  since  the  result  of  rerunning a non-rerunnable job might be
           catastrophic.
    
           The -S option allows users to specify the  program  (usually  a  shell)
           that  will  be  invoked  to  process  the script of the batch job. This
           option has been modified to allow a list of shell names  and  locations
           associated with different hosts.
    
           The  -u  option is useful when the submitting user is authorized to use
           more than one account on a given host, in  which  case  the  -u  option
           allows  the  user to select from among those accounts. The option-argu-
           ment is a list of user-host pairs, so that the submitting user can pro-
           vide  different  user  identifiers for different nodes in the event the
           batch job is routed. The -u option provides a  lot  of  flexibility  to
           accommodate  sites with complex account structures. Users that have the
           same user identifier on all the hosts they are authorized to  use  will
           not need to use the -u option.
    
           The  -V  option  allows  users  to export all their current environment
           variables, as of the time the batch job is submitted, to the context of
           the processes of the batch job.
    
           IEEE Std 1003.1-2001  appears  to  incorporate  all the common existing
           practice on potentially conforming platforms.
