Platform (Scali) MPI 5.6
Table 5-5. Platform MPI Wrapper Scripts
Wrapper Script Name
Language
mpicc
mpic++
C
C++
mpif77 Fortran 77
mpif90 Fortran 90
To compile your program in C using the default compiler, type:
$ mpicc mpi_app_name.c -o mpi_app_name
To invoke another compiler, in this case PathScale, use the -cc1 option, for
example:
$ mpicc -cc1 pathcc mpi_app_name.c -o mpi_app_name
Running Platform MPI 5.6 Applications
Here is an example of a simple mpirun command running with four processes,
over PSM:
$ mpirun -np 4 -machinefile mpihosts mpi_app_name
or if you have not set /opt/scali/etc/ScaMPI.conf to use PSM by default,
use:
$ mpirun -np 4 -machinefile mpihosts -networks=infinipath
mpi_app_name
Once installed, Platform MPI uses the PSM transport by default. To specify PSM
explicitly, add -networks infinipath to the above command.
To run Scali MPI over InfiniBand Verbs, type:
$ mpirun -np 4 -machinefile mpihosts -networks ib,smp mpi_app_name
This command indicates that ib is used for inter-node communications, and smp
is used for intra-node communications.
To run over TCP (or IPoIB), type:
$ mpirun -np 4 -machinefile mpihosts -networks tcp,smp mpi_app_name
