Then users can request this complex. As the complex is attached to all exechosts, this won't prevent any jobs from being scheduled to any node (unless you want to exclude some nodes from this feature), but it can only be used once per job per exechost. This way you can get up to the specified number of slots per exechost and block other jobs on this exechost. NB: The complex can also be attached to a queue, which would then block other jobs from using the same queue on a particular exechost, but could still get slots on this exechost from another queue (in case you have more than one queue per exechost). -- Reuti _______________________________________________ users mailing list [email protected] https://gridengine.org/mailman/listinfo/users
