Hi Nehemiah
I never tried to build OpenMPI with SunStudio, but it should work.
(I did with Gnu, Intel, PGI and Open64, the latter still has Fortran90
problems.)
For starters, I would just try the recipe in the OpenMPI FAQ:
http://www.open-mpi.org/faq/?category=building#build-compilers
replacing the intel compiler names by the corresponding Solaris studio.
If you installed the compilers in Rocks /share/apps, any shared
libraries they may have will be available at runtime on all nodes.
BTW, /share/apps would be the best place to install OpenMPI as well
(in a subdirectory of your choice).
This will avoid installing on all nodes, making OpenMPI available
through the NFS mounted /share/apps directory.
For modest-sized clusters this scales well.
If you have many hundreds of nodes, you may want a different approach
(e.g. making OpenMPI RPMs and rebuilding the nodes with them.)
If you have Infiniband and/or Torque or SGE, read these FAQs:
http://www.open-mpi.org/faq/?category=building#build-p2p
http://www.open-mpi.org/faq/?category=building#build-rte-tm
http://www.open-mpi.org/faq/?category=building#build-rte-sge
The FAQ are the de-facto OpenMPI documentation:
http://www.open-mpi.org/faq
Worth reading.
My two cents,
Gus

I want to compile openmpi to work with the solaris studio express or
solaris studio. This is a different version than is installed on
rockscluster 5.2 and would like to know if there any gotchas or
configure flags I should use to get it working or portable to nodes on
the cluster. Software-wise, it is a fairly homogeneous environment with
only slight variations on the hardware side which could be isolated
(machinefile flag and what-not)
Please advise
