setDevice: Get and set the current device.

In gmatrix: GPU Computing in R

Description

On systems with multiple GPUs the current device may be set or investigated with these functions.

Usage

setDevice(device,force=FALSE,silent=FALSE,...)
getDevice()
listDevices()

Arguments

device	Device number to set the device to
force	Force reset of the tuning parameters even if they have already been set
silent	Prints a message if TRUE
...	Arguments to set the tuning parameters. It's not a good idea to mess with these at this point.

Details

All operations are performed on the current GPU device only. An error will be returned if the user attempts to perform an operation on a device that is not the current device. Details of the available devices can be obtained with the 'listDevices' function.

Value

setDevice returns TRUE. getDevice returns the current device number. listDevices returns a data.frame with information about the available devices.
