8 Program Communicating Jobs 3 Use createCommunicatingJob to create a communicating job object for your cluster. 4 Create a task, run the job, and retrieve the results as usual. Supplied Submit and Decode Functions There are several submit and decode functions provided with the toolbox for your use with the generic scheduler interface. These files are in the folder matlabroot/toolbox/distcomp/examples/integration In this folder are subfolders for each of several types of scheduler. Depending on your network and cluster configuration, you might need to modify these files before they will work in your situation. Ask your system administrator for help. At the time of publication, there are folders for PBS (pbs), and Platform LSF (lsf) schedulers, generic UNIX-based scripts (ssh), and Sun Grid Engine (sge). In addition, the pbs, lsf, and sge folders have subfolders called shared, nonshared, and remoteSubmission, which contain scripts for use in particular cluster configurations. Each of these subfolders contains a file called README, which provides instruction on where and how to use its scripts. For each scheduler type, the folder (or configuration subfolder) contains wrappers, submit functions, and other job management scripts for independent and communicating jobs. For example, the folder matlabroot/toolbox/distcomp/examples/ integration/pbs/shared contains the following files for use with a PBS scheduler: Filename Description independentSubmitFcn.m Submit function for an independent job communicatingSubmitFcn.m Submit function for a communicating job independentJobWrapper.sh Script that is submitted to PBS to start workers that evaluate the tasks of an independent job communicatingJobWrapper.shScript that is submitted to PBS to start workers that evaluate the tasks of a communicating job 8-8 deleteJobFcn.m Script to delete a job from the scheduler extractJobId.m Script to get the job’s ID from the scheduler getJobStateFcn.m Script to get the job’s state from the scheduler
