I would love to test it with a i586/i686-compatible build. (f951 should
be sufficient that can be used as a replacement in one of those regular
builds provided on FX's web page. Unfortunately I don't have the
resourced to build gfortran myself.)

The essential problem was actually the virtual memory used by f951
when I last tried to compile the app with MPI enabled. I think the
first "benchmark" is to have the module files of the reworked
example to all have the same size and essentially same contents.

Thanks,
