[Beowulf] Gaussian in parallel

Geoff et al.,

We have had several conversations with customers about Gaussian.
Apparently some datasets don't scale with Linda, and those customers
generally either run serial or with OpenMP. I wouldn't be surprised if
the people who said here that gaussian "didn't run in parallel" have
such datasets.

If I understand correctly, some customers have source code and others
do not. So this is probably talking about the official binaries and
not what customers may have compiled themselves.

But, hey, I don't know, I've never seen the source!
