I'm sorry to revisit this issue (I'm sure its driving you nuts) but
can you explain how I could do the following...
I have three queues - small, medium and large and I want to make only
jobs with say less than 8 processors go into small, 9-15 medium and
16+ in large. I have set the nodect setting accordingly but this means
that only 8 processors in the whole of small can run.
What I need is a way to apply limits to jobs only and not to queues as
a whole. So, I'd like to run multiple jobs from small with each job
being forced to use 8 processors or less but the queue as a whole able
to use as many processors as are available.
Thanks for your help.
