Thank you to take time for me. In our cluster we have critical resources named DCh (specific hardware used through TCP sockets) .
The DChs are limited in number and if a high priority job is submitted to the cluster it must be able to take DCh to lower priority jobs if needed. (it is what I mean by preemption) To do this I tryed to used: - A "global complex" to manage the DChs. (works fine) - The parameter subordinate_list on lists which were sharing the "global complex" The objective was to allow high priority job to requeue the lower priority job but it doesn't seems to work with job asking for complex resources. Do you have any solution? -----Message d'origine----- De : Reuti [mailto:[email protected]] Envoyé : vendredi 22 mars 2013 17:17 À : HUMMEL Michel Cc : [email protected] Objet : Re: [gridengine users] preemption mechanism with virtual resources Am 22.03.2013 um 15:59 schrieb HUMMEL Michel: > > Sorry for the mistake, it works when queues are sharing the same resources > (nodes) > > But I cannot make it to work with A Global Consumable Resource : > http://gridscheduler.sourceforge.net/howto/consumable.html > > I am trying to create a global resource which can be preempted by high > priority job. Resources will never be preempted in advance, as SGE can't look ahead. The suspension by subordination is the result of a new job starting on an exechost. But neither slots nor any memory will be freed or alike. E.g. on a gobal level already used up licenses will still be in use from SGE's point of view.
