Job Scheduling (RSS)
An issue came to our attention after Windows HPC Server 2008 shipped regarding the way we set affinity on the processes within a job. There are actually two places where we set affinity: 1. The Node Manager (the service on each node responsible for starting

Microsoft Research has an interesting project called Dryad which is investigating programming models for distributed data-parallel problems. If you've heard some of the hype around map/reduce programming or the Hadoop framework, you might be familiar

SUA is a very nice tool for porting Unix/Linux application, but it can also be used to submit job. You just have to set the path to the HPCS binary into your PATH variable : With BASH : export PATH=$PATH:"/dev/fs/C/Program Files/Microsoft HPC Pack/Bin"

For ISV application you have to set some environments variables on the compute node. You can set this variable by hand, but if you have many nodes it can be long. So, the idea of this post is how can set them attaumaticaly ? Use the HPCS tools : You can

HPC uses HPC sessions to support the service-oriented architecture (SOA) programming model based on Windows Communication Foundation (WCF). Sometimes troubleshooting errors from this SOA based applications could be challenging. However this tip I'm about

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,

Shahrokh was nice enough to film and post a video of me walking through the HPC Job Scheduler and some of its new features at SuperComputing 2008. You can check out the video up on YouTube . In the video I cover many of the different scheduler interfaces

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. That, on top of some changes made in a QFE , led us to do an updated doc on using filters.

We find many of our Windows HPC Server 2008 deployments are going into environments where there are existing Linux (and Linux HPC) solutions. It is possible to configure these two environments to achieve integrated authentication, file sharing and job

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

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

I was asked today where there was a quick explanation of how to submit a job from the command line, and I realized that I didn't have a really good answer. So I figured I'd do a blog post (first in a while, I know!) on how to do this. Starting Simple

We've posted a white paper on how Job Templates can help you manage your cluster. You can check out the white paper here: https://windowshpc.net/Blogs/jobscheduler

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
