[molpro-user] Clash between multiple instances of Molpro on one node

[Bastiaan J. Braams]

Hi all,

I'm using the sequential version of Molpro, but running multiple
instances in parallel on a multiprocessor computer.  Sometimes this
results in unreproducible, seemingly random failures of the Molpro
runs, usually already at the Hartree-Fock level.  What might be the
cause and what might be a remedy?  Sorry not to be more specific, it
is happening to me on quite different computer systems and for
different Molpro calculations, and with 2002.6 and also 2006.2.
Should I look for a cause in memory contention, disk contention,
something in my directory structure, or maybe there is some subtlety
that needs to be taken into account when Molpro is installed?
