a powershell problem
We've gotten reports of an installation glitch that makes it so that node management cmdlets won't work when run from a remote client (they'll work just fine run on the headnode) due to a registry key that doesn't always get set up correctly. Fortunately, there is a simple work around! If you are trying...

Creating Submission and Activation Filters
There were a lot of questions about how to use Activation and Submission Filters to help customize queue managmeent and do things like license-aware scheduling.

Clusrunning with Windows HPC Server 2008
One of our most popular features in the Compute Cluster Pack was clusrun (known to you GUI users as “Remote Command Execution”), which allowed you to run a command line command across a set of cluster nodes in parallel, with their output piped back to you on the client.

MPI Process Placement with Windows HPC Server 2008
We get an awful lot of questions about how to go about getting the desired process placement across nodes in an MPI job (just check our forums if you don’t believe me), so I thought I’d post here to shed some light on the things that are possible. Requesting Resources The first thing you need...

Parameter Sweeps are one of the most common types of jobs that get run on HPC clusters, and we've done some work in Windows HPC Server 2008 to make them easier (and faster) than ever. Today I'll dig in a little on what's different and how to take advantage of these new features. For those familiar...

What the heck is a “Job Template” and why should I care?
Job Templates are one of the most whiz-bang new features in HPC Server 2008, but we've gotten a lot of feedback from the community that you don't really know what they're for or how to use them. So I figured a quick post here might help solve that problem by introducing you to one of the most powerful...

This week, I’d like to take some time to explain how a new feature, Multi Level Resource Allocation, can help you get the most out of your applications.
