Subject: [OMPI users] Compiler Choice in openmpi
From: Wen Hao Wang (wangwhao_at_[hidden])

Hello all:

I have two questions to set openmpi compilers.

1. How can I change/set Fortran compiler used after installing openmpi?
I installed openmpi-1.2.5-2 on RHEL5.2 Server with x86_32 arch. The rpm has
been shipped RHEL images. I directly installed the rpms without compiling
the source code. Now all mpi* compiler wrappers point to GNU compilers. I
need change to use Intel compilers by default. How should I do? I caught
one message about configuration files /etc/openmpi-mca-params.conf and
$HOME/.openmpi/mca-params.conf. Not sure whether these two files can help.
While I failed to find detailed explanation for them.

2. Can I use Intel compiler and GNU compiler together?
I am not sure whether I can use two types of compiler to compile one
program. For example, use GNU c/c++ compiler and Intel Fortran compiler
together to compile my project.
