Can anybody tell me what is the differenz between
cudaHostAlloc (void **ptr, size_t size, cudaHostAllocMapped)
cudaHostAlloc (void **ptr, size_t size, cudaHostAllocDefault)?
I don’t understand the advantage of mapped page lock memory in opposite to normal page lock memory. In both cases the device can access the host memory direct. Which advantage has an address mapping? And which methode is faster?
