NAME

       smpirun - Exectute MPI programs in the SimGrid simulator

SYNOPSIS

       smpirun  [SMPI OPTIONS]… -platform <platform.xml> -hostfile <hostfile> program [SIMULATION
       OPTIONS] [PROGRAM OPTIONS]

DESCRIPTION

       smpirun car run MPI programs that were compiled with  smpicc  on  top  of  the  simulator.
       Basically,  it  generates  a  deployment files from the provided hostfile (if needed), and
       launches the simulation with the right arguments. It is intended to  be  easy  to  use  to
       regular MPI users.

MANDATORY PARAMETERS

       -platform <platform.xml>
              XML file describing the platform on which we want to deploy the program

       -hostfile, -machinefile <hostfile>
              Hostfile listing all the machines in use

SMPI OPTIONS

       The  smpirun  itself  accepts  some optional parameters, that are not to be mixed with the
       configuration options described in the next section.

       -help  Print the usage and a résumé of the available options

       -keep-temps
              Do not remove the generated files after execution.

       -wrapper <command>
              Use command to run the program (e.g. "valgrind", "gdb --args", "rr  record").   You
              usually want to use the "-foreground" option as well in order to have a TTY.

       -foreground
              Run  the  child  process in the foreground.  This gives the child process access to
              the TTY.

       -map   Display the machine on which each process rank is mapped.

       -np <numprocs>
              Use that amount of processes. By default, there is the same number of processes  as
              there are of hosts in the hostfile.

       -no-privatize
              Disable  the globals privatization, that is activated by default.  This should only
              be necessary if you use dynamic libraries, but you should probably link  statically
              instead of disabling this. Do not link statically against SimGrid, only the others.

       -trace Activate   the  trace  mechanism  if  available  (equivalent  to  --cfg=tracing:yes
              --cfg=tracing/smpi:yes)

       -trace-ti
              Activate time independent tracing.

       -trace-comment <comment>
              Put a comment on the top of the trace file.

       -trace-comment-file <file>
              Insert the content of the file at the head of the trace file as a comment.

       -trace-grouped
              Group MPI processes by location.

       -trace-resource
              Trace resource utilization.

       -trace-file <tracefile>
              Name of the tracefile

SIMULATION OPTIONS

       You  can  change  many   simulation   parameter   on   the   command   line   by   passing
       --cfg=parameter:value  after  the  program  name.   A full list of existing parameters and
       their             meaning             can             be             found              at
       http://simgrid.gforge.inria.fr/simgrid/latest/doc/options.html

       Here are some options commonly used with SMPI:

       --cfg=smpi/cpu-threshold:XXX
              Only simulate computation chunks that last more than XXX seconds.

       --cfg=smpi/simulate-computation:no
              Disable  the  simulation  of all computation chunks (that are still executed on the
              host machine).
