When specified explicitely the (WorkSize mod LocalSize) is required to be zero. 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. Kernel internal for-loops in GPU devices cause large performance penalties. The CPUAdjust parameter should be used only if the device is of CPU type. LocalSize is also called workgroup size. The for-loop pattern expected inside the kernel looks like this: 

where BLOCK_LEN matches OPENCL_BLOCKLEN.
