Jonathan,Thanks for the patch. I will test it and i have also write access to the subversion tree. So if more sites have tested and it works than we can commit it to maui trunk source.

Hi Maui folks, GPUs in Maui are a long standing problem. Last year a patch was sent by Mariusz Mamoński [1], which works based on GRES parameters. I've just made GPUs kind of working, by enhancing that patch. Please find attached the resulting patch, which works well for Maui 3.3.1. It defines a special GRES named "gpu" which works as expected on my test cases. Note that GRES behaviour seems quite confused as sometimes they are mentioned as consumable. This patch annihilates this behaviour, for the needs of GPUs. To use the patch: get the sources of maui-3.3.1 and patch them: patch -p1< ../Patch-for-gpu-GRES.patch then compile as usual. You have to configure the GPUs in maui.cfg: NODECFG[nodename] GRES=gpu:2 Then when queuing jobs you can request GPUs with (Torque syntax): qsub -W x=GRES:gpu@1 I hope this helps, please test this and enhance to your needs!
