Compatibility Considerations
Because spmd is a new keyword, it will conflict with any user-defined functions or
variables of the same name. If you have any code with functions or variables named
spmd, you must rename them.
Composite Objects
Composite objects provide direct access from the client (desktop) program to data that
is stored on labs in the MATLAB pool. The data of variables assigned inside an spmd
block is available via Composites in the client. When a MATLAB pool is open, you can
also create Composites directly from the client using the Composite function. See also
Distributing Arrays and Running SPMD.
Configuration Validation
The Configurations Manager is enhanced with the capability for validating
configurations. Open the Configurations Manager on the MATLAB Desktop by clicking
Parallel > Manage Configurations. For more information, see Validate Profiles.
Rerunning Failed Tasks
When using a job manager, if a task does not complete due to certain system failures, it
can attempt to rerun up to a specified number of times. New properties of a task object to
control reruns and access information about rerun attempts are:
• MaximumNumberOfRetries
• AttemptedNumberOfRetries
• FailedAttemptInformation
Enhanced Job Control with Generic Scheduler Interface
The generic scheduler interface now allows you to cancel and destroy jobs and tasks and
to investigate the state of a job. The following new properties of the generic scheduler
object facilitate these features:
• GetJobStateFcn
• DestroyJobFcn
