    DESCRIPTION

           Most LAM/MPI used can disregard this page.
    
           A  process  schema  lists the system processes that will constitute the
           LAM environment on a particular node.  LAM developers will find process
           schemata very useful for debugging and for generating custom systems.
    
           Separate  default  configurations  files  are normally used for booting
           either the single-daemon version  (conf.lam)  or  the  external-servers
           version (conf.otb).  The single-daemon version is used by default.  The
           external-servers version is  typically  used  by  LAM  developers  when
           debugging  LAM  services.  The -c option to hboot(1) specifies the file
           name of a custom process schema.  This capability is not available with
           lamboot(1).
    
           Application  programs can be booted with the LAM environment by includ-
           ing the program name in the process schema.
    
    
    

    STRUCTURE AND SYNTAX

           The process schema grammar defines three types of statements: comments,
           processes, and options.
    
           Comments begin with # and terminate with a newline.
    
           Process  statements  consist of a filename, command line arguments, and
           possibly options local to the process.  The command line arguments  are
           passed to the process when it is started.  The process options are used
           by the booting tools before starting the process.
    
           Filenames may include application programs and any of the  system  pro-
           cesses listed below.
    
           bforward    bufferd helper, forwards remote messages.
    
           bufferd     creates, kills, sweeps, and states buffers.
    
           dli_inet    sends data on network connections.
    
           dlo_inet    receives data from network connections.
    
           echod       echoes messages; can be used to test nodes and links.
    
           filed       serves file access.
    
           flatd       provides symbolic access to node memory.
    
           iod         handles stdio data of processes.
    
           kenyad      controls and monitors processes.
    
           kernel      coordinates message passing.
           Processes are started in the order given in the process schema, and for
           LAM, the order is important.  The kernel must be first.
    
           Process  options are placed inside braces {} following the command line
           arguments.  Process  options  consist  of  a  keyword  followed  by  an
           assigned  value  in parentheses.  Options that are not explicitly given
           have default settings.  Options inside  braces  in  process  statements
           apply  only  to that process.  Options outside process statements apply
           to all processes that  appear  later  in  the  process  schema,  unless
           locally overridden.  All the options are listed below:
    
           inet_topo   a  string of dli_inet or lamd options, global only, default
                       null
    
           rtr_topo    a string of router options, global only, default null
    
           delay       waiting time in seconds after process boot, default 0
    
           The inet_topo and rtr_topo options can be overridden from  the  command
           line of hboot(1) using the -I and -R options respectively.
    
    
    

    EXAMPLES

           Following  are example process schemata.  The first file is used for an
           OTB node in LAM.
    
           ##
           ## typical LAM process schemata
           ##
    
           lamd $inet_topo
    
           The second file is used by LAM developers to control each server as  an
           independent process, typically during debugging.
