[Wien] forrtl: severe (174): SIGSEGV, segmentation fault occurred

[L. D. Marks]

If you are not using -static (which one cannot on Redhat 9.0) you need to
make sure that LD_LIBRARY_PATH is set correctly to find the needed shared
libraries, e.g. include in your .bashrc (with appropriate locations)

LD_LIBRARY_PATH=/opt/intel/mkl61/lib/32:/opt/intel_fc_80/lib:/opt/intel_cc_80/lib
export LD_LIBRARY_PATH

This needs to be there for all nodes, so the libraries may need to be nfs
mounted (or perhaps better, copied).

As a caveat, mkl and fort have some duplicate library names, with
different code. I asked Intel about this some time ago (i.e. which was
better) and got no useful answer.
