GNU Fortran for Bluegene - compiler and toolchain

[Keith Refson]

Does anyone have any experience building a recent version of gfortran
for use on the IBM Blue Gene. Building the cross-compiler for the double
hummer 450d is a lot tougher than a native build on x86 linux, and the
integration/obtaining the rest of the toolchain has so far defeated me.

We really need a serious alternative to the IBM compilers on this
platform, so if anyone has any experience with this, I'd like to hear
from you.

Thanks

Keith Refson

What is this world coming to? The Blue Gene is rather expensive kit.
One would think that for that money they could include a decent
compiler.

Let's face it: there was DEC in its prime, then a huge gap, then
everybody else.

Hi Keith

I've sent my IBM email address to the address in your signature (assuming I
demangled it right). Please feel free to contact me, as I can forward you
to our HPC focal. I've also discussed your post with our support team and
they're eager to help with any IBM compiler problems you may have.

Regards

Rafik
