For everyone who loves the Excel functionality in the HPC Pack 2008 R2 Enterprise version, we have written up some best practices for using the HPC macros.
Then we have released an update to the Network Troubleshooting Report portion of the tool pack. This is a minor bug fix for people who are using Server 2008 on some of their compute nodes. You can download the updated version on the HPC Pack 2008 / 2008 R2 Tool Pack page.
And, we also released an update (aka qfe/hotfix/patch) for folks using HPC Pack 2008 R2 Service Pack 1. The update fixes two problems
1) Submitting a job from a user account in a domain that does not have a trust relationship with the headnode’s domain will fail. After applying this fix (to the cluster and the client) the submitter can enter appropriate credentials via the Job Console or ‘runas’ from command line / powershell.
2) For clusters that allow jobs to be preempted there is a case where a heavily stressed head node can receive a request from a user to cancel a job at the same time it was trying to preempt that job can then it reports to the user that the cancellation occurred, but the actually got preempted/requeued.
