Hi,
Just to be clear, I started from Steve's rpms, upgraded the torque
version and reimplemented the TMPDIR patch. The motivation for this was
that the 1.2.0 version contained a patch needed for mpiexec.
I've seen no problems here with the new version. But...probably one of
the larger sites using torque should take a look---just to ensure that
there aren't any hidden problems with the upgrade.
