Some newbie questions

    Question

  • I've been researching Windows HPC and had a few general questions:

    1) Can jobs be configured to use processor cores as compute nodes? For example, if we have a small three server cluster where each server has dual quad core processors, can we break down the job at the core level so that it acts like 24 compute nodes?

    2) Assuming #1 is possible, do we still only need 3 HPC licenses?

    3) I've read that Server 2008 Standard support up to four processors per server. Does this mean that it can only use half the processor cores on a dual QC server?

    I know these are rudimentary questions, but I haven't been able to find a solid answer online.

    Thanks for your help!

  • HPC jobs can be assigned resources by server, socket or core depending upon your application needs. In the case of your 3 dual quad core servers, you could assign jobs to 3 servers, 6 sockets, or 24 cores. So you can launch 24 processes, which would be like 24 nodes.

    HPC Server is licensed per server, so you would need 3 licenses.

    Server 2008 is limited to 4 sockets, not cores. In your case, you are only using 2 sockets.
