How to run CPU tasks on GPU Workers?
I submit a job (gpu=0) on gpu worker, the task occupy all gpu on gpu node.

OpenPAI Environment:

• OpenPAI version: v1.0.1

@IamSunGuangzhi Could you describe your question more clearly? Which scheduler did you use, k8s default scheduler or HiveD scheduler? And what configuration did you use?

If you are using HiveD scheduler, you could always submit a job with 1 GPU and run CPU only process in that job. There's no way to submit CPU only job on GPU nodes if you also want to run GPU jobs on that node which will break cell assignment in scheduler.

You can either set up CPU nodes and corresponding VC for CPU jobs, or change to k8s default scheduler.
