[gpaw-users] GPAW with mpirun on multiple hosts - revisited

[Jesper Rude Selknæs]

Hi

I ran your tests, and it pointet me in the right direction. My
submission script was not setting the tmpdir, and by setting it, my
jobs completes flawlessly. My home dir is on a NFS by the way.

I anybody is interested, i do have the output of the tests, but since
the problem was resolved, I won't spam the list, unless somebody
really wants the results.

Thanks a lot for a simple solution.

R.

Jesper
