[Beowulf] large scratch space on cluster

[Hearns, John]

Actually, it is not GAMESS which is causing the problem but Molpro. The
reason 
why it needs that much space is simply the size of the molecule and the 
functional ( CCSD(T) ). Both are not in favour of a fast job with little

scratch space. I don't think there is much I can do in terms of the
program 
side. If I want to run the job, I need more scratch space.



Yes, but do these scratch files have to be on a central disk server,
or is it possible to have them local to the nodes?
If local, you have a much easier problem.

I can say that $VENDOR put in one very whizzy cluster which had four
fast SCSI drives striped
together for local scratch storage, for running a finite element code.
It went like gangbusters.

In your case, you could either put pairs of striped drives in each
compute node.
