Hi all,
I'm sort of new to configuring SGE. There's something I'd like to do,
but I don't know how to do it...or, more precisely, I don't know what
it's called so I'm not sure what I should be looking for in the
documentation.
I'm administering a single computer. So, it manages the queue and
also is where the jobs are run.
I'd like to create queues that limit the number of threads that can be
used. For example, suppose it has 4 cores and 4 x 2 = 8 threads. Is
it possible to create queues that:
1) Can use at most n threads (i.e., n=2). If the user places
something on the queue that uses 4 threads while running, the user's
job is either killed or suspended.
2) Can stick to using only one core. So, if threads is n=2, then
both threads are on the same core ("guaranteed").
I guess (2) is impossible...I'm not sure if the system knows which
thread goes with which core.
But I guess (1) is possible but I don't know which option to set.
What I'd like to prevent is having a queue with 2 threads and users
putting programs with 4 threads on it. (I'd rather create another
queue with 4 threads so that they can put it on that queue instead.)
Thank you for your help!
Ray
