+%description
+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 essencially zero latency
+involved in the copy process. This might be useful when low latencies
+are required.
