cudaSetValidDevices: Set a list of devices that can be used for CUDA

In duncantl/RCUDA: R Bindings for the CUDA Library for GPU Computing

Description

Sets a list of devices for CUDA execution in priority order using device_arr. The parameter len specifies the number of elements in the list. CUDA will try devices from the list sequentially until it finds one that works. If this function is not called, or if it is called with a len of 0, then CUDA will go back to its default behavior of trying devices sequentially from a default list containing all of the available CUDA devices in the system. If a specified device ID in the list does not exist, this function will return cudaErrorInvalidDevice. If len is not 0 and device_arr is NULL or if len exceeds the number of devices in the system, then cudaErrorInvalidValue is returned.

Usage

cudaSetValidDevices(device_arr, len)

Arguments

device_arr	List of devices to try
len	Number of devices in specified list
