On a similar note, anyone know if it is possible to effect the following:
* My job wants to run on 8 nodes. I realise that there could be some dual
around, but if I get one of them, I only want it to count as a single as I
want all the memory the node can get. I also want the other
processor marked as occupied as I really don't want to share! I am willing
* Where possible allocate jobs to separate nodes rather than both processors
a dual. e.g. If I have a job which wants 4 processors of a system which
they should prefer 4 separate nodes rather than 2 duals. A sort of
rather than depth-first strategy.
Also same strategies when applied to duals with hyper-threading.
I received this hypo(hyper?)thetical request from a colleague who is used to
HPC to do his work.
