DeviceInfo: Query and select the devices

In Jiefei-Wang/gpuMagic: An openCL compiler with the capacity to compile R functions and run the code on GPU

Query and select the devices

Description

This is a set of functions to query the device information and select which device should be used in the computation

Usage

getDeviceList()

getDeviceInfo(i)

getCurDevice()

setDevice(i)

getDeviceIndex()

getJobStatus(i)

Arguments

i	A 1-based device index, it should be an integer

Details

'getDeviceList()': The function is used to obtain all the opencl-enable devices

'getDeviceInfo()': Get the ith device information, call 'getDeviceList()' first to figure out the index before using this function

'getCurDevice()': Get the information of the current devices

'setDevice()': Set which device will be used in the opencl, call 'getDeviceList()' first to figure out the index before use this function

'getDeviceIndex()': Get the index of the current devices

'getJobStatus()': Query the current job status in a device

Value

'getDeviceList()': No return value, the result will be printed in the console

'getDeviceInfo()': A list with the device information

'getCurDevice()': No return value, the result will be printed in the console

'setDevice()': No return value

'getDeviceIndex()': An integer representing the device index

'getJobStatus()': A character representing the device status

Examples

#Get the available devices
getDeviceList()

#Get the information of the first device
getDeviceInfo(1)
#Get the information of current used devices
getCurDevice()
#Use the first device
setDevice(1)
#Use two devices
#setDevice(c(1,2))
#Get the index of the current devices
getDeviceIndex()
#Get the job status in the first device
getJobStatus(1)
