== Single GPGPU per node ==
{{Template:Op menubar}} {{TOC_right}}
A simple batch setup that assumes a physical node and its componenent GPGPU card expose a single '''Job Slot''' would simplify Resource Centre setup. Each GPGPU node could be partitioned from the non-GPGPU nodes using an access-control-list. However, most modern physical nodes contain and expose multiple CPU-cores to the batch system. If the physical system supports '''Virtualisation''', a CPU-core could be allocated to the GPU on the phsical node, and a single virtual machine could expose the remainder of the job slots. For example: Assume the physical host (wn1) has 8-cores, we can configure the node to declare (in torque) "np=1" to the batch system. If we create a  VM with "np=7", then all cores can be allocated to the batch system.

== Multiple GPGPUs per Physical Node ==
'''[[GPGPU_Working_Group| << GPGPU Working Group main page]]'''
Similar to the Virtualisation example above, a physical node with '''N'''-gpgpu cards could be configured with


''np=#NUM_OF_GPGPUS''

A virtual machine could then present
* [[GPGPU-WG:GPGPU_Working_Group_KnowledgeBase:Batch_Schedulers:SchedulerScenarios:GPUOnlyQueue | GPGPU Queues assuming 1-core per GPGPU ]]
''np=#NUM_OF_CORES-#NUM_OF_GPGPUS'' job slots
* [[GPGPU-WG:GPGPU_Working_Group_KnowledgeBase:Batch_Schedulers:SchedulerScenarios:MixedCPU_GPU_Queue | GPGPUs as a subset of queue resources]]
