Run Batch Workload on a Mixed Infrastructure (Windows Azure Worker Nodes & On-Premise HPC Server 2008 R2 Compute Nodes)

With the introduction of SP1 of HPC Server 2008 R2 it is possible to run workload on Windows Azure. If you want to be able to off-burst your batch application (= extending the infrastructure from classic on-premise servers to cloud based Azure worker nodes) you need to set specific environment variables within the on-premise server infrastructure. Here is a…


Process Affinity and Windows HPC Server 2008 SP1

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 jobs and tasks) sets processor affinity on each task to…

License aware job application filter

When many HPC applications have to be used on a cluster, most of the time they are using the well know FlexLM license manager to provide floating licenses. The CCS Job scheduler doesn’t do, by default, a license aware scheduling, but by extending it with a Job Activation Filter this feature can be achieved. This…


Fun and interesting ways to run MPI jobs on CCS

posted Tuesday, October 03, 2006 6:07 PM by elantz | 0 Comments   MS-MPI is identical to MPICH2 in most respects but one area of difference is MS-MPI’s secure execution and interaction with the CCS Job Scheduler.  Hopefully, this post will shed some light on how you can leverage the CCS Job Scheduler to run your…
