[torquedev] Mixing Torque 2.110 and 2.3.0 on a cluster ?

[Chris Samuel]

Hi folks,

We're looking at upgrading our Opteron cluster to 2.3.0
as we *really* want the cpusets support so I'm wondering
if anyone has tried running a mix of 2.1.10 and 2.3.0 on
a single cluster ?

My main concerns are:

1) Will the 2.1 and 2.3 mom's talk to each other correctly ?

2) Can 2.1.10 mom's talk to a 2.3.0 server (and visa versa) ?

3) We have heaps of mpiexec's, OpenMPI, etc, built against
2.1.10, I'm hoping that the fact that it's all now shared libs
should make it painless, but has anyone actually tested this ? :-)

We have $enablemomrestart set to 1, so the mom's should
notice when they are swapped to the new version (assuming
it follows symlinks correctly to the new binary).

cheers,
Chris
