Ross:
Thanks. Yes, I plan to use already installed Intel
Fortran V 9.1.036 and C++ 9.1.042 for both Amber and
MPI (instead of the GNU compilers I have on Linux
Debian amd64 etch).
Actually, that Intel Fortran already provides runtime
to a QM code (NWChem 5.0, which, on my machine, does
not depend on MPI for parallelization) installed on
that dual-core opterons machine:
francesco_at_deb64:~$ locate libimf.so
/opt/intel/fce/9.1.036/lib/libimf.so
/opt/intel/cce/9.1.042/lib/libimf.so
francesco_at_deb64: ~$
Should that be taken into account, or could that give
rise to any problem, with the Amber9/openMPI
compilations?
cheers
