  (comments on your previous posts are closed, so I'll ask here) Does ClojureCL work with POCL[0]? I ask b/c ARM seems to have abandoned OpenCL-on-CPU with NEON, but it can still be done using POCL[1]. I've gotta say, ClojureCL just looks fantastic and a very slick way to deal with tight-loops (without having to do FFI with C++). And writing OpenCL kernel interactively is going to be a huge win. This might be what pushes me to switch from C++ to Clojure :) [0] - https://github.com/pocl/pocl https://github.com/pocl/pocl [1] - https://www.cnx-software.com/2017/11/14/first-opencl-encounters-on-cortex-a72-some-benchmarking/ https://www.cnx-software.com/2017/11/14/first-opencl-encount... PS: Hope you have a post about profiling/benchmarking kernels

    ClojureCL is driver-agnostic. As long as the OpenCL platform implementation (POCL) is OpenCL-compliant, ClojureCL should work (but I have not tried). Regarding profiling/benchmarking, you can measure wall-clock time very precisely with Criterium, and you can also use kernel profiling built into OpenCL, as explained in OpenCL in Action and demonstrated here: https://github.com/uncomplicate/clojurecl/blob/master/test/clojure/uncomplicate/clojurecl/examples/openclinaction/ch07.clj https://github.com/uncomplicate/clojurecl/blob/master/test/c...

      Thanks for getting back to me and thanks for your amazing work. Seems POCL doesn't support a few things: http://portablecl.org/docs/html/features.html http://portablecl.org/docs/html/features.html I'll need to dig around a bit more. The OpenCL drivers are a rather confusing mess (especially on the open source side of things)

        OTOH, even Intel CPUs support OpenCL, so practically there aren't such many cases where you can't work with a "real" OpenCL implementation.
