Parallel computing on a cluster

Hi,
I am working on a cluster composted by 4 processors each one with 12 workers (for a total of 48 workers). I am using MATLAB 2013b and I am quite sure there are installed the Distributed Computing Server together with the Parallel Computing Toolbox (there are the respective folders into the "toolbox" folder). The preferred number of workers in a parallel pool is setted to 48 but all the parallel loops I try work on only 12 workers. I suspect that this is due to the fact that I am not using (correctly or at all...) the Distributed Computing Server but, from what I could find with an online search, I could not understand what I have to do to "activate" (or, maybe better, "set") it. Can anyone help me?
Thanks,
Nicola

Hi Nicola,
first of all you will need to make sure you really use the cluster (and not your local machine). When you click on "Parallel" in the tool strip and then on "Manage Cluster Profiles". Do you see "local" only or are there "local" and something else? If it's "local" only, it means, you use only your machine, not the cluster at all.
If this is the case, click on "Discover Cluster" to "find" your cluster. Configure it and then it should work.
