You can change many simulation parameter on the command line by passing
\fB--cfg\fR=\fIparameter\fR:\fIvalue\fR after the program name.
A full list of existing parameters and their meaning can be found at

Here are some options commonly used with SMPI:
.TP
! timeout 120
$ ./replay_multiple description_file ${srcdir:=.}/../../platforms/small_platform_with_routers.xml ${bindir:=.}/deployment.xml --log=smpi.:info --cfg=maxmin/concurrency-limit:100
> [0.000000] [xbt_cfg/INFO] Configuration change: Set 'maxmin/concurrency-limit' to '100'
-> [0.000000] [smpi_kernel/INFO] You did not set the power of the host running the simulation. The timings will certainly not be accurate. Use the option "--cfg=smpi/host-speed:<flops>" to set its value.Check http://simgrid.org/simgrid/latest/doc/options.html#options_smpi_bench for more information.
