Subject: Re: [OMPI users] Intel compiler libraries (was: libnuma issue)
From: Francesco Pietra (chiendarret_at_[hidden])

As a quick answer before I go to study yous and Douglas mail: the
desktop toward which I was sshing is a single processor 10-years old
desktop with nothing about intel or openmpi. It only has ssh software
to run amber procedures on remote machines. I can try your suggested
ssh toward a parallel computer, but, in any case, my running of
openmpi and Amber is normally on single-node uma-type computers.
Nothing outside them is involved in the parallel calculation. It is
the situation described by Douglas. The computation should work (and
it worked in the past) even if the computer is removed from the
internal network.
