    Graphics driver crash since 13.4 when using atomic_inc

    Bdot

      Hi,

       

      I'm using a HD5770 on Win7-64 with Cat13.10.

       

      Since 13.4 till today, my appication crashes the GPU driver or even causes blue screens. Now I've been able to provide a small test case based on the MemoryOptimizations example. I just added a 3rd parameter and used it similar to my application: The first word of that uint array is a counter of how many words are in it, increased by atomic_inc. After that, the entries start.

       

      Can someone show me what is wrong? Or suggest how to get around this problem?

       

      Other users reported that the driver crash also happens on GCN-based GPUs, on Windows 8. The last driver known to not crash was 13.1.

       

      Thanks.
