Functions

public module function fclFindDevices_1(ctx, vendor, type, nameLike, extensions, sortBy) result(deviceList)

Arguments

Type	Intent	Optional	Attributes		Name
type(fclContext),	intent(in),		target	::	ctx	Context containing device for command queue
character(len=*),	intent(in),	optional		::	vendor	Filter device list based on platform vendor. Specify multiple possible vendors in comma-separate list
character(len=*),	intent(in),	optional		::	type	Filter device list based on device type. Specify at least one of 'cpu', 'gpu', default: 'cpu,gpu' (both)
character(len=*),	intent(in),	optional		::	nameLike	Filter devices based on device name. Look for this substring in device name.
character(len=*),	intent(in),	optional		::	extensions	Filter devices based on supported device extensions. Specify comma-separated list of OpenCL extension names, e.g. cl_khr_fp64. See clGetDeviceInfo Extensions specified are requirements: devices are filtered-out if they don't support all extensions specified.
character(len=*),	intent(in),	optional		::	sortBy	Sort device list based on either 'memory': total global memory, 'cores': total number of compute units, 'clock': maximum clock speed

Return Value type(fclDevice), allocatable, (:)
