Version 1 says to signal wait [0] when the kernel is finished - which is the right thing to do. Version 2 is asking your clEnqueueNDRangeKernel () to wait for the events in wait before it starts that kernel [which clearly won't work]. On it's own, queue.finish () [or clFinish ()] should be enough to ensure that your kernel has completed.
