Hi, my script utilizes parfor and I was wondering if there was a way to compile it into a standalone .exe such that it can be used across all types of multi core CPUs? ie if it is deployed on a 4 core comp it uses all 4 cores....it will use all 6 cores in a 6 core CPU etc?

It is possible, but not the default. See http://www.mathworks.com/matlabcentral/answers/26472-how-to-define-local-matlabpool-size-at-runtime-for-parallel-computing-toolbox-use-in-compiled-matl

(I didn't think I'd be able to find that old discussion!)

I believe that if you did not hard code the cluster size into the local configuration, it would do what you want. The default cluster size is one worker per core*, so if you didn't hard code that in the configuration, I'd think it would determine it.

*- When I say "core", I mean a real compute core, not a hyper-threaded one.
