Okay. I was late... > Actually, this is something that I'd like to ask OSCAR users: > > - How is the MPI support for OSCAR?

Our customers almost never use the plain OSCAR MPIs because the gcc compiler is too slow compared to commercial ones. So we have some derived packages. Something like: lam, lam-gm, lam-intel, lam-gm-intel, corresponding for pgi (on Opteron). > - If/when you install additional MPI implementations, do you use the > switcher mechanism to swap between them?

Yes, we use switcher and modules directly and teach the users how to do it in their job scripts (call switcher to change env on remote nodes AND module to change env of current shell...). To the background: I'm developing a cluster middleware stack called HPC Linux for my company. It's infrastructure is currently OSCAR (almost 3) with a bunch of additional packages. It is heavilly changed to work with SuSE 9.0 on Opteron (that has some limitations), TaoLinux (ia32, x86_64, ia64) and RHEL3 (all three architectures). With some limitations we can manage inhomogeneous clusters, I'd very much like to see mainline OSCAR enabled to do that...
