Using OpenMP or OpenCL? Per OpenCL spec, opencl driver should be thread-safe, and Junyan implemented the multi-thread support in beignet. That is to say Beignet is thread-safe. I am not sure whether Junyan has more comments on how to debug the issue. By the way, if you can provide a test case to reproduce the issue, it would be much helpful. Thanks!
