Christopher,

Correct me if I am wrong below...

Sasha,

I think he is compiling from the OFED release.  Unfortunately I believe this
only allows you to specify one complier for the entire "distro".

Christopher,

If you absolutely can't figure out why icc's libraries are being found, I can
think of 2 alternatives.

1) Try and run install.pl 2 times with the different compilers.  First to build
   only the packages required for MPI with icc.  Then all the management and
   support stuff with gcc.  I don't know if this is possible because I am
   afraid to run install.pl as root and have it corrupt one of my nodes right
   now.  However, looking inside the script leads me to believe you can select
   the packages you want built.

2) Extract (from the OFED tarball) the OpenSM and management source rpms and
   build them with gcc.  That list would be:

      opensm-3.2.2-1.ofed1.4.beta1.src.rpm
      infiniband-diags-1.4.1-1.ofed1.4.beta1.src.rpm
      libibcommon-1.1.1-1.ofed1.4.beta1.src.rpm
      libibmad-1.2.1-1.ofed1.4.beta1.src.rpm
      libibumad-1.2.1-1.ofed1.4.beta1.src.rpm

Here at LLNL we have been building OFED pieces by hand for years.  YMMV...

Hope this helps,
Ira
