If I usecudaMemcpy()then do I must at first to set a flagcudaSetDeviceFlags( cudaDeviceMapHost )? Do I have to usecudaMemcpy()pointers which I got as result from the functioncudaHostGetDevicePointer(& uva_ptr, ptr, 0)? Are there any advantages of functioncudaMemcpyPeer()...
I sent 1GB data from GPU0 to GPU1, and found that NCCL is always faster than cudaMemcpyPeerAsync . In my mind, the speed of NCCL and cudaMemcpyPeerAsync is same with PCIE. Do you have any idea why NCCL is faster than cudaMemcpyPeerAsync ....
