Running pmode Interactive Jobs on a Cluster
4-15
Running pmode Interactive Jobs on a Cluster
When you run pmode on a cluster of workers, you are running a job that is much like
any other communicating job, except it is interactive. The cluster can be heterogeneous,
but with certain limitations described at http://www.mathworks.com/products/parallel-
computing/requirements.html; carefully locate your scheduler on that page and note
that pmode sessions run as jobs described as “parallel applications that use inter-worker
communication.”
Many of the job's properties are determined by the cluster profile. For more details about
creating and using profilies, see “Clusters and Cluster Profiles” on page 6-14.
The general form of the command to start a pmode session is
pmode start <profile-name> <num-workers>
where <profile-name> is the name of the cluster prifile you want to use, and <num-
workers> is the number of workers you want to run the pmode job on. If <num-
workers> is omitted, the number of workers is determined by the profile. Coordinate
with your system administrator when creating or using a profile.
If you omit <profile-name>, pmode uses the default profile (see the
parallel.defaultClusterProfile reference page).
For details on all the command options, see the pmode reference page.
