I suggest that you leave OpenCL alone for a moment (well, maybe right after you finish whatever you're currently doing to it), and instead get POMELO's SIMD code into the tree first. Both SSE* and AVX2, please. I think you haven't done that yet, right? This should be one and the same format called simply pomelo, but using whatever code is most appropriate for the current build of john (plain C, with SSE* intrinsics, or with AVX2 intrinsics - that's 3 versions) - just like we have for other SIMD-enabled formats. We need this to have baseline performance numbers on CPU. Surely they are greater than for the non-SIMD code you got in so far, and once confirmed this would mean that your OpenCL kernels are not performing that well (including on CPUs). Thanks, Alexander
