I am really confused :wacko:
we have - each node in cluster has 4 GPUs (nvidia tesla s1070) and 16 cores (4 quad CPU).
we want - create different queues (1) for pure CPU jobs and (2) for mixed GPU+CPU jobs.
Case (1) means that all jobs use CPU on a node.
Case (2) means that all jobs use GPU + CPU on a node.
How we can organise these by PBS or torque?
For CPU jobs we must create queue which have only 12 CPU per node. (other 4 CPU are used by GPU)
For GPU jobs we must create queue which have 4 CPU per node.
Is it necessary that 1 GPU requires 1 CPU to function or can we use 4 Virtual Processors(VP) on 2 cores to drive 4 GPU’s and
remaining 14 for CPU jobs. ?
does anyone have idea reagarding configuring workload manager on clusters have CPU+GPU combination for computing batch jobs??
I tried hard on the Internet but couldn’t get useful information…
any suggestions…thanks in advance
