The way we have done things like this is to define 1 GPU per GPU node
(that is all the GPU cores are considered part of a single processing
element on the node). Each node that has a GPU gets 1 GPU resource.
When you submit a job for the GPU, it will run, in part, on the host
processor, as well as on the GPU itself. You cannot run a job on one
core of the GPU, these are dedicated specialized processors.
To submit the job requesting a GPU (assuming you named the consumable
resource to be "GPU") you would
qsub -l GPU=1 ...
where ... are the rest of your job arguments and script. To define the
consumable, you can do this through the gui. Create a complex, make it
requestable, consumable, default of 1, and an integer type.
Then add this complex to any compute nodes with the GPU. Once this is
done, you can submit jobs as above.
I think Chris D has some pages on the wiki about this.
