[GE users] TMPDIR for mpi jobs?

In the README in $SGE_ROOT/mpi/myrinet there is advice to set
$TMPDIR as a shared filesystem.

I've run OK on two systems just using a local TMPDIR

Have changed one system over to a shared tmp directory -
and there are problems being reported in the output,
such as /shared/tmp/xxx.queue_name directory not found

Anyone else seen similar problems?

Is it really necessary to have a shared TMPDIR for tightly
integrated Myrinet jobs?
