Cuda 无挥发性

谁能给我建议一种方法来释放CUDA中的易失性全局内存变量

volatile unsigned *d_queue_L12;
err = cudaMalloc((void **)&d_queue_L12, CORES*MAX_12*Cache_Sets_L2*sizeof(volatile unsigned));
if (err != cudaSuccess)
{
    fprintf(stderr, "Failed to allocate space to L12 QUEUE vector (error code %s)!\n",     cudaGetErrorString(err));
    exit(EXIT_FAILURE);
}

err = cudaFree(d_queue_L12);
if (err != cudaSuccess)
{
    fprintf(stderr, "Failed to free L2 FLAG COUNT vector (error code %s)!\n", cudaGetErrorString(err));
    exit(EXIT_FAILURE);
}

给出一个错误：

---

错误：“volatile unsigned int*”类型的参数与“void*”类型的参数不兼容

err = cudaFree((void *)d_queue_L12);

这是什么主机编译器？在这种情况下，您希望通过使用volatile实现什么？
