Thread Subject: MATLAB and Kerrighed

Hello everyone!

We're about to build our lab's first Linux Beowulf cluster. So far I'm looking at Kerrighed to use as the single system image for the diskless nodes.

How does MATLAB migrate processes to available processors?
Do I need a parallel computing toolbox?
Can I run a MATLAB script on the head node only, then set it up so that it automatically distributes heavy tasks across the cluster?

I'm trying to get a general idea of how this works. So far I have seen this at an MIT site:
http://www.ll.mit.edu/mission/isr/pmatlab/pmatlab.html

Thanks in advance!

Hi Kristofer,

The Parallel Computing Toolbox (http://www.mathworks.com/products/parallel-computing) is a client side toolbox used for submitting jobs to a scheduler (e.g. TORQUE, PBS Pro, LSF, etc.), which then starts up the MATLAB Distributed Computing Server (http://www.mathworks.com/products/distriben).

Looking at Kerrighed, it appears to have its own scheduling manager. If so, you can make use of the generic scheduler interface or you might try the MathWorks Job Manager for a scheduler.

Let me know if you have any other questions.
