Check out It was
originally running Linux, but we switched to Solaris due to the fact that
the code generated by Sun's fortran compilers is, for various applications
we tried, 20-50% faster than g77 generated code. I can't recall how well
it did on C apps. It is possible to run some Solaris apps under linux,
however, be prepared to do some kernel hacking to get them to work
correctly. I was never able to get an Solaris-compiled MPI app to run on
more than two machines, but we had alot of success with one of our serial
codes. Let me know if you need any more info - I'll be more than happy to
provide it.
