Hi Mike,
We currently use an Intel Xeon submit node and all our compute nodes
are amd opterons.
If you use separate queues it should be fine.

Hi Ryan and all others.
Here we have a problem we've not seen yet.
I've parted the cluster with 11 Xeon nodes (named ruche) and 14 Opteron
nodes (named callas).
I've made pure opteron queues and pure xeon queues with :
- in the nodes file
xeonname np=2 xeon ruche
...
opteronname np=2 opteron callas
- in the queues definitions
set queue ruche resources_default.neednodes = ruche
set queue callas resources_default.neednodes = callas
- in the MAUI config
CLASSCFG[callas] MAXJOB=48
CLASSCFG[ruche] MAXJOB=22
And we thought all was all right !
BUT if we submit more than 48 jobs in the callas queue, the 49th job is
submitted to a xeon node !!!
How can I ensure this never happens ?
(what I found is :
# checknode xeonname
checking node xeonname
...
Features: [xeon]
Attributes: [Batch]
Classes: [callas 2:2][ruche 2:2][batch 2:2]
how comes the "Features" tell only "xeon" "ruche" but we can see
"callas" in the classes ?????)
Thanks for any help...
