How to determine if running on a MS HPC headnode

Thu, 28 May 2009 14:44:55 Z

Hi,

I am developing a Python tool for submitting jobs (reservoir simulation case) to Microsoft Compute Cluster (CCS1 and HPC) or running directly on a Windows machine.
The tool runs fine when submitting jobs with 'job submit' command, however user is also able to run an executable directly on a Windows machine and here the problem starts - I need to check if I am running on a headnode to pick up different executable (the one which uses MS MPI rather than MPI).

In the past I was checkng for presence of CcsScheduler process running, but it doesn't seem to be the best approach since HPC renamed the process and my condition is no longer valid.

I will appreciate any help.

Thanks,
Krzysztof

I believe the v2 scheduler process is HPCScheduler if that helps at all. You can also try running cluscfg view (or from PSH Get-HpcClusterOverview) which will provide you the name of the scheduler you are connecting too . . . you can just compare that to the name of the machine you're currently running on.

Thanks,

Hi Josh,

Thanks for reply.

Another question emerges: 'is Cluster Name always the same as headnode machine's name?'.
I have seen quite a few CCS/HPC clusters and in every case the cluster's and headnode's name were the same, however is it always the case?

Regards,
Krzysztof

Yep, we use the name of the head node to identify the cluster.
