Parallel execution on Windows HPC Server 2008 R2

I am trying to run distributed jobs on a HPC Server 2008 R2. While defining the parallel execution settings I tried both HpcServer2008 and CCS setting. Neither worked. The Matlab version at hand is 2010a.

CCS:

Find Resouce: Passed

Distributed Job: Passed

Parallel Job: Failed. With the error:

Error initialising MPI: Computer type "PCWIN" does not have MSMPI support

2. HpcServer2008:

Find Resource: Failed. With the error:

Failed to use cluster client utilities for version HPCServer2008

Any help would be appreciated.

OS: Windows HPC Server R2 64bit

Matlab: 2010a 32bit

Any advice would be appreciated.

Hi Ohad,

R2010a does not support 32-bit clients for HPC Server 2008. You either need to submit with a 64-bit client, or you will have to use ClusterVersion = CCS.

For the failed CCS Parallel Jobs: What is the ClusterMatlabRoot property set to in your configuration? It looks like you may have installed 32-bit MATLAB on the cluster.

[Ohad]

The ClusterMatlabRoot is set to the location of the Matlab installation C:\Matlab\...

Indeed, I have a 32 bit Matlab installed on my cluster. Is that a problem?

Regarding the HpcServer2008 ClusterVersion and 32-bit clients. Was this problem solved in newer Matlab versions?

Hi Ohad,

You should install 64-bit MATLAB on the cluster nodes because there are some required libraries for our HPC Server integration that are not available in the 32-bit version of MATLAB.

On the 32-bit clients: this is not something that we support at the moment, but we are aware that this a limitation and it is high up on our list of priorities.

Thanks, Elwin
