    A plug-in that retains every Event created by clEnqueueReadBuffer and waiting at least one second before releasing it.

    Note

    This is a workaround for https://github.com/ThoughtWorksInc/Compute.scala/issues/51

  8. trait HandleEventInExecutionContext extends OpenCL

    Permalink

    Note

    HandleEventInExecutionContext should be unnecessary because only OpenCL calls to create contexts or command-queues, or blocking OpenCL operations are undefined behavior, according to https://www.khronos.org/registry/OpenCL/sdk/1.2/docs/man/xhtml/clSetEventCallback.html and we don't use those forbidden functions. Our usage should be fine according to the OpenCL specification. However, AMD SDK always crashes for any reentry calls (e.g. https://travis-ci.org/Atry/DeepLearning.scala/jobs/318466522), no matter if they are blocking or not. There is also similar bug in Intel's OpenCL implementation As a workaround, always enable this HandleEventInExecutionContext for Intel's and AMD's OpenCL implementation.

    Make the calls to createKernels and createKernel synchronized.

    Make the calls to createKernels and createKernel synchronized.

    Note

    If you are using Intel OpenCL SDK, you will need this plug-in as a workaround
