Hello!<br/>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?<br/><br/>Best regards,<br/>Ilya© 2009 Microsoft Corporation.
