MinimumNumberOfWorkers - Specify minimum number of workers to perform job tasks

Description

With MinimumNumberOfWorkers you specify the minimum number of workers to perform the evaluation of the job's tasks. When the job is queued, it will not run until at least this many workers are simultaneously available.

If MinimumNumberOfWorkers workers are available to the job manager, but some of the task dispatches fail due to network or node failures, such that the number of tasks actually dispatched is less than MinimumNumberOfWorkers, the job will be canceled.

Characteristics

Usage	Job object
Read-only	After job is submitted
Data type	Double

Values

The default value is 1. You can set the value anywhere from 1 up to or equal to the value of the MaximumNumberOfWorkers property.

Examples

Set the minimum number of workers to perform a job.

jm = findResource('scheduler','type','jobmanager', ...
          'name','MyJobManager','LookupURL','JobMgrHost');
j = createJob(jm);
set(j, 'MinimumNumberOfWorkers', 6);

In this example, when the job is queued, it will not begin running tasks until at least six workers are available to perform task evaluations.
