Thank you Jesse. I am using Enterprise SLES15SP6 as the OS. I have not introduced the cgroup functionality in my environment. I can think about it and will see if this solution works out. but is there any other way to use without Cgroup to achieve the same. Batch job requests are fine 2 jobs with each one GPU request works fine. in the case of mix( 1 batch job and other Interactive job) creating the problem.
Is there a way I can run a job and apply the exclusive way only on GPU resources? Regards Navin.
