affy (version 1.50.0)

snow-startstop: Starting and Stopping SNOW Clusters

Description

Functions to start and stop a SNOW cluster and to set default cluster options. Wrapper around original start-stop commands from SNOW to hide the cluster object.

Usage

makeCluster( ...)
stopCluster(cl)

Arguments

...

cluster option specifications, for details see SNOW package.

cl

cluster object.

Details

makeCluster starts a cluster of the specified or default type and returns NO reference to the cluster. The reference is stored in an internal environment (.affyParaInternalEnv) and will be automatically used from the functions in affyPara. For further parameters and documentation see the SNOW package. stopCluster should be called to properly shut down the cluster before exiting R. If it is not called it may be necessary to use external means to ensure that all slave processes are shut down.

Examples

makeCluster(2)
	stopCluster()
