Submits the Kernel to cmdQueue for computation with specified WorkSize.

Pascal
procedure Enqueue(const cmdQueue: TOpenCLCommandQueue; WorkSize: integer; CPUAdjust: boolean = true); overload;
Description

Setting CPUAdjust to true will reduce WorkSize by factor OPENCL_BLOCKLEN and assume presence of kernel internal for-loops. Kernel internal for-loops can significantly speed up execution of the kernel on CPU devices lowering the function call overhead. The CPUAdjust parameter is used only if the device is of CPU type. The for-loop pattern expected inside the kernel looks like this:

size_t i = get_global_id(0); size_t tIdx = i*BLOCK_LEN; size_t tIdxLen = tIdx + BLOCK_LEN; if (tIdxLen > Length) tIdxLen = Length; for (i = tIdx; i < tIdxLen; i++) { }

 

where BLOCK_LEN matches OPENCL_BLOCKLEN.
