Does PBS allow changing queue priorities dynamically?
At our site, we have large (highest priority), medium and small (lowest priority) queues and a highly oversubscribed load. The queue run limit is 1 for large.
Still, a large fraction of #jobs is in small queue. Is it possible to design a policy whereby if there are a SUFFICIENT # of waiting jobs in small queue, the top job from large queue is delayed to clear out small jobs en masse? We would like to do this without resorting to starvation.
