Hi, One solution is to use subordinate queues to make queues mutually exclusive:
Create the exclusive attribute in qconf -mc: name exclusive shortcut excl type BOOL relop == requestable YES consumable NO default 0 urgency 0 In queue1.q conf: subordinate_list queue2.q=1,queue3.q=1 complex_values exclusive=TRUE In queue2.q conf: subordinate_list queue1.q=1,queue2.q=1 complex_values exclusive=TRUE etc... 2016-05-24 18:01 GMT+02:00 Manuel Pérez Jigato <manuel.pe...@list.lu>: > hello > > I am running my code on an AMD cluster (32 nodes, each with 16 cores) > under the sun grid engine scheduler, version 6.2u5p2, and alongside openMPI > 1.4.4 > > I have realised that my calculations suffer from a huge performance loss > (even 40 times) due to other jobs running on the same nodes > > I have been unable to control the actual nodes in order to make them use > the "fill-up" mode, all 16 cores must be selected in a strict manner > > Previous SGE versions used to have the option "qsub -l exclusive..", but > 6.2u5p2 does not. > > Will you please give me a hint of how to solve my loss of performance > problem? > > thanks a lot > > Manuel Perez Jigato > > > _______________________________________________ > users mailing list > users@gridengine.org > https://gridengine.org/mailman/listinfo/users > >
