5–Using Other MPIs
Platform (Scali) MPI 5.6
To compile your program in C using the default compiler, type:
$ mpicc mpi_app_name.c -o mpi_app_name
Running Platform MPI 7 Applications
Here is an example of a simple mpirun command running with four processes,
over PSM:
$ mpirun -np 4 -hostfile mpihosts -PSM mpi_app_name
To run over InfiniBand Verbs, type:
$ mpirun -np 4 -hostfile mpihosts -IBV mpi_app_name
To run over TCP (which could be IPoIB if the hostfile is setup for IPoIB interfaces),
type:
$ mpirun -np 4 -hostfile mpihosts -TCP mpi_app_name

Platform (Scali) MPI 5.6
Installation
Platform MPI 5.6 was formerly known as Scali MPI Connect. The version tested
with this release is 5.6.4.
Follow the instructions for downloading and installing Platform MPI 5.6 from the
Platform (Scali) web site.
Setup
To run over PSM, by default, add the line networks=infinpath to the file
opt/scali/etc/ScaMPI.conf.
If running over InfiniBand Verbs, Platform MPI needs to know which InfiniBand
adapter to use. This is achieved by creating the file
/opt/scali/etc/iba_params.conf using a line such as:
hcadevice=qib0
For a second InfiniPath card, ipath1 would be used, and so on.
Compiling Platform MPI 5.6 Applications
As with QLogic MPI, QLogic recommends that you use the included wrapper
scripts that invoke the underlying compiler (see Table 5-5). The scripts default to
using gcc/g++/g77.
