It's hard to help you with that without knowing more detail--OS version, hardware, CPU/GPU, what specific program are you running (e.g. the PyOpenCL demos? the test suite?) Every commit to pyopencl gets tested on Apple hardware, so I'm a little surprised that you're seeing so much trouble. Here's an example: https://gitlab.tiker.net/inducer/pyopencl/-/jobs/43619 Andreas _______________________________________________ PyOpenCL mailing list PyOpenCL@tiker.net https://lists.tiker.net/listinfo/pyopencl
