Hi all,
is there a limitation regarding the copy of host pinned-memory to a cuda Array? I tried to alloc the pinned memory with both cudaMallocHost and cudaHostAllocPortable, and both are crashing when running the copy.
I found this post The Official NVIDIA Forums | NVIDIA but I have not this problem of allocating the memory in a thread that would be terminated when running the copy by another thread.
Any idea?
Thanks

cudaHostAlloc( (void**)&m_buffer, getByteSize(), cudaHostAllocPortable );
// using 'new' operator works just fine
cudaMemcpy3DParms copyParams = {0};
copyParams.srcPtr = make_cudaPitchedPtr((void*)mypreviousbuffer, volumeSize.width*sizeof(char4), volumeSize.width, volumeSize.height);
copyParams.dstArray = myArray;
copyParams.extent = volumeSize;
copyParams.kind = cudaMemcpyHostToDevice;
cutilSafeCall( cudaMemcpy3D(©Params) ); // it crashes here
