Chelsio Communications T5 IWARP, The Movie
Description
Chelsio’s Terminator 5 ASIC offers a high performance, robust third‐generation implementation of RDMA (Remote Direct Memory Access) over 40Gb Ethernet – iWARP. The Terminator series adapters have been field proven in numerous large clusters, including a 1300‐node cluster at Purdue University. Chelsio supports several Message Passing Interface (MPI) implementations through integration within the OpenFabrics Enterprise Distribution (OFED), which has in-boxed Terminator drivers since release 1.2. Continuing on the performance curve established by T3 and T4, the T5 design cuts T4′s end-to-end RDMA latency in half to about 1.5µs. Benchmark reports available below show that T5 offers performance that meets or exceeds the fastest FDR InfiniBand speeds in real‐world applications.
