Prehash CUDA error #34

Closed rsmmnt closed 5 years ago

rsmmnt commented 5 years ago

There is an error that occurs from time to time:

2019-05-03 08:02:12,234 INFO [GPU 0 miner] GPU 0 read new block data ERROR: CUDA failed at src/prehash.cu: 1019 Miner is now terminated

It's at cudaMemcpy call and seems like it tries to read from wrong chunk of memory

   CUDA_CALL(cudaMemcpy(
        (void *)&len, (void *)(invalid + 2 * N_LEN), INDEX_SIZE_8,
        cudaMemcpyDeviceToHost
    ));

so probably kernels before that call can yield corrupted value of invalid
