"WebRDMA over Converged Ethernet (RoCE) is supported with PVRDMA. The beauty of RoCE is that a ethernet fabric can be used. There's not explicit requirement for a seperate fabric like with Infiniband. The ethernet fabric needs to support RDMA, primarily by supporting Priority Flow Control (PFC). PVRDMA supports both RoCE v1 and v2. " - Rdma over infiniband

WebOur RDMA-based MPI implementation currently delivers a latency of 6.8 microseconds for small messages and a peak bandwidth of 871 Million Bytes (831 Mega Bytes) per second. … WebKey difference between Ethernet and Infiniband, which makes Infiniband faster, is RDMA (Remote Direct Memory Access). DMA (in networking) is an operation which access the memory directly from the NIC (Network Interface Controller), without involving the CPU. RDMA is the same idea, but the direct memory access is done by a remote machine.
