Most often "*" would be requested then for this string (and all must be the same once it is elected), but would allow to request "opteron*" when you have "opteron275" and "opteron2384" in the cluster besides several "xeon...".

This is very similiar to the (also very handy) feature in LSF where
you select a resource flag [type==same]. This ensures that a jobs only
runs on system considered to be the same i.e. arch. If the RFE you
mention covers this, it will get my vote directly.

I know I can set up complexes with the CPU type and request that, but I don't actually care what the value is so long as it is the same for all hosts participating in the parallel job. Is this possible?
