MATLAB: Does matlabpool take a long time to open

Parallel Computing Toolbox

While everything seems to work fine and validation completes, for some reason matlabpool takes a very long time to open. Is there a fix for this?

Best Answer

If MATLAB is encountering a licensing issue then this will cause matlabpool to start slowly. To resolve the issue with matlabpool, you need to resolve the issue with MATLAB's licensing. To troubleshoot startup issues caused by licensing, see this article:

MATLAB: Matlabpool RAM occupation

Does the RAM usage come back down when running matlabpool close? Remember that matlabpool open 8 is equiavelent to starting MATLAB 8 times on your machine. Each instance will use approximately as much RAM as if you were starting MATLAB manually.

MATLAB: Matlabpool local files

Did you validate your SGE configuration? Do you have the SGE-specific submit files on the path? These submit function files are required to submit SGE commands to the queueing system.

We have an SGE scheduler with MATLAB DCS which works pretty well.

THe files for R2012a are:

SGEClusterInfo.m    getJobStateFcn.m
communicatingJobWrapper.sh  getRemoteConnection.m
communicatingSubmitFcn.m  getSubmitString.m
createSubmitScript.m    independentJobWrapper.sh
deleteJobFcn.m      independentSubmitFcn.m
extractJobId.m

The files for R2011 b and older are

createSubmitScript.m
destroyJobFcn.m  
distibsubmit.m  
distributedJobWrapper.sh 
distributedSubmitFcn.m   
extractJobId.m  
SGEClusterInfo.m
submitjob.m
getJobStateFcn.m
getRemoteConnection.m
getSubmitString.m
parallelJobWrapper.sh
parallelSubmitFcn.m

These files should be availabel from the Mathworks.. Please follow the readme that come along with these files as you will have to edit some parts of these files to suit your SGE cluster queueing system..
