Do you read the Beowulf lists? You might want to stick to version 7 in
any event because people are reporting bugs/slowness with version 8.
The Intel compiler appears to be becoming much more gcc compatible: GCC
is also improving and may provide good performance for many cases.
You may also want to look at specific high performance Fortran from PGI
/ Pathscale - who have better Linux support in general. I have found
that if you ask commercial vendors nicely and outline a realistic
problem to them e.g. I'm buying a 512 node cluster which will run Debian
- can you provide drivers for your special interconnect boards? - they
are much more willing to help
Have fun
