Dear Matlab experts, I am using a Matlab script to run my functions in parallel. For that, I am using parcluster. When I type in the shell lscpu, I get the following:

In the Cluster Profile Manager I set NumWorkers to 144 and NumThreads to 18. However I get an out-of-memory error at submit function. Error indicates 'Unable to create new native thread'. How should I set the Cluster Profile Manager parameters in order to optimize my resources and execution time? Thanks very much in advance.
