Hi,
I'm using Matlab in the HPC cluster of my department. I know that the HPC has a matlab parallel license for up to 32 workers, but if I:
1)Open matlab
2)Go to Parallel--Manage Configurations--right click on Local--Properties--Number of workers(Clustersize)=32
3)type
matlabpool open 32
it gives me the error ??? Error using ==> matlabpool at 125 Error when using the 'scheduler' section of the configuration 'local': The ClusterSize for a local scheduler must be between 1 and 8
Do you know how can I solve this problem?

You need to set the HPC cluster as your default, or you need to name the cluster when opening matlabpool, like so:
matlabpool open hpccluster 32
where 'hpccluster' is the name of the profile.

Thank you, but I don't know how to set the HPC cluster as my default: if I go to Parallel--Manage Configurations I can see only the option Local.

In that case, you need to create a cluster profile pointing at your actual cluster. You might want to start here: http://www.mathworks.co.uk/help/distcomp/clusters-and-cluster-profiles.html.
You'll need to know what sort of scheduler is running the cluster (this might be the MathWorks job scheduler, MJS, or something else like HPCServer, LSF, PBSPro, Torque, GridEngine, ...)
