Communication libraries (MVAPICH2, UCX) can take advantage of GDRCopy. if available on the systems. While GPUDirect RDMA is meant for direct access to GPU memory from third-party devices, it is possible to use these same APIs to create perfectly valid CPU mappings of the GPU memory. The advantage of a CPU driven copy is the very small overhead involved. That might be useful when low latencies are required. To use it, please check whether the GDR COPY module is loaded on the involed machines. # lsmod | grep gdrdrv "
