Dear Jesse, Thanks, the calender or quota using cron externally just looks into the time constraint. but the real essence i was trying to research this mailing list and online is for dynamic resource allocation. that is i have a number of resources under one queue, and these can shrink in size or scale up depending on work load and how busy or idle they are. if the serial workload is not much and batch jobs queue is huge than turn some of these into the batch queue to handle some of the work load. that is the basic thing, of course there will be other conditions for jobs to run such as having the right license to check in, and right resources and mount points in the node. but i just want to concentrate first of all on the ability to dynamically/automatically allocate resources to a queue as per current, or past workload.
