Where to report conformance test failures?

OpenCL

following code fails for me, on Mac Sierra, using Radeon Pro 450. Where/how to report it?


    int N = 100000;

    float *a = new float[N];

    cl_mem a_gpu = clCreateBuffer(context, CL_MEM_READ_WRITE, N * sizeof(float), 0, &err);
    checkError(err);
    for(int it = 0; it < 100; it++) {

        float value = 123.0f + it;
        err = clEnqueueFillBuffer(queue, a_gpu, &value, sizeof(value), 0, N * sizeof(float), 0, 0, 0);
        checkError(err);
        clFinish(queue);

        err = clEnqueueReadBuffer(queue, a_gpu, CL_TRUE, 0,
                                             sizeof(cl_float) * N, a, 0, NULL, NULL);
        checkError(err);
        clFinish(queue);

        cout << it << " a[N - 1]=" << a[N - 1] << endl;
    }
    delete[] a;




Expected output:
0 a[N - 1]=123
1 a[N - 1]=124
2 a[N - 1]=125
3 a[N - 1]=126
4 a[N - 1]=127
5 a[N - 1]=128
6 a[N - 1]=129
7 a[N - 1]=130

actual output:
0 a[N - 1]=0
1 a[N - 1]=0
2 a[N - 1]=0
3 a[N - 1]=0
4 a[N - 1]=0
5 a[N - 1]=0
6 a[N - 1]=0
7 a[N - 1]=0
8 a[N - 1]=0
9 a[N - 1]=132

I have no idea either… just piling on a few more issues (OpenCL 1.2) that I’ve encountered:

I haven’t had a reason try clEnqueueFillBuffer yet, but it’s good to know to expect trouble there as well.
