MPICH-SCore version 2.0 (ch_score2): Compilation of an MPI application

Choice of a compiler

C application
Use mpicc(1) as the compiler. Mpicc works as a linker also. It should link the application with MPICH-SCore version 2.0 library when the option "-device ch_score2" is specified.
C++ application
Use mpic++(1) to compile and link the application. Mpic++ links the application with MPICH-SCore version 2.0 library when the option "-device ch_score2" is specified.
FORTRAN77 application
Use mpif77(1) to compile and link the application. Mpif77 links the application with MPICH-SCore version 2.0 library when the option "-device ch_score2" is specified.
FORTRAN90 application
Use mpif90(1) to compile and link the application. Mpif90 links the application with MPICH-SCore version 2.0 library when the option "-device ch_score2" is specified. This distribution package does not include any configuration for mpif90. You should install a FORTRAN90 compiler and re-compile the SCore package if you need mpif90. See the documentation to add configuration for an optional compiler.

Compilation of a sample application

alltoall.c is an MPI application that measure the performance of the MPI_Alltoall function. The application is written in C. Use mpicc to compile the application as the follows:

% mpicc -device ch_score2 -O2 -o alltoall alltoall.c
