How to limit node load?
How to limit node load?
- Hello!
I'm using HPC Server 2008 on CoPC cluster, so I need to limit number of cores, available to hpc job scheduler on each node. E.g. I have 25 nodes with 8 cores on each, with 25*8=200 cores total. I want to allocate to HPC scheduled jobs not more than 7 cores on each nodes. Is there any way to do this?
Best regards,
Ilya

- Hi,
I don't think there is a supported way to do this.
A quick workaround would be to issue a ever running 1 core job per node which simply blocks the core and does not do anything.
However no job requiring "Use this node exclusively for this job" is runnable then.
Perhaps you could hack the database of the scheduler to reduce the numbers of cores?

- As an additional note, we do hope to add support for this in version 3.
Thansk!
