Syntax

shutdown(cluster)
shutdown(MJScluster,'At',D)
shutdown(MJScluster,'After',event)
shutdown(MJScluster,'After',numhours)

Description

example

shutdown(cluster) shuts down the cluster immediately.

example

shutdown(MJScluster,'At',D) shuts down the cluster at the time specified by the datenum, datevec, or datetime D. D is interpreted in the local time zone unless D is a datetime with TimeZone specified.

example

shutdown(MJScluster,'After',event) shuts down the cluster after the specified event event has occurred. event can be 'never' or 'idle'. A cluster is 'idle' immediately when there are no running jobs, queued jobs, or running pools. The cluster is eligible for shutdown if 'idle' for more than 5 minutes, and is guaranteed to shut down within 60 minutes.

example

shutdown(MJScluster,'After',numhours) shuts down the cluster after numhours hours, as measured from the time the method is called.

shutdown(cluster);

Specify date and time to terminate a cluster using a datenum, datevec, or datetime. The datetime can (optionally) have a TimeZone specified.

shutdown(MJSCluster,'At',datenum('2017-02-22 19:00'));
shutdown(MJSCluster,'At',datevec('2017-02-22 19:00'));
shutdown(MJSCluster,'At',datetime(2017, 2, 22, 19, 0, 0,'TimeZone','local');
shutdown(MJSCluster,'After','never');
shutdown(MJSCluster,'After','idle');
shutdown(MJSCluster,'After',10);

MATLAB Parallel Server for Amazon EC2® cluster, specified as cluster object created using parcluster.

Example: shutdown(cluster);

MATLAB Parallel Server for Amazon EC2 cluster, specified as cluster object created using parcluster.

Example: shutdown(MJScluster);

Date and time, specified as a datenum, datevec, or datetime. D is interpreted in the local time zone unless D is a datetime with TimeZone specified.

Example: shutdown(MJSCluster,'At',datenum('2017-02-22 19:00'));

Example: shutdown(MJSCluster,'At',datevec('2017-02-22 19:00'));

Example: shutdown(MJSCluster,'At',datetime(2017, 2, 22, 19, 0, 0,'TimeZone', 'local'));

Event to shut down the cluster, specified as 'never' or 'idle'. A cluster is 'idle' immediately when there are no running jobs, queued jobs, or running pools. The cluster is eligible for shutdown if 'idle' for more than 5 minutes, and is guaranteed to shut down within 60 minutes.

Example: shutdown(MJSCluster,'After','idle');

Number of hours after which the cluster shuts down, specified as scalar, measured from the time you call shutdown.

Example: shutdown(MJSCluster,'After',10);
