The fifth-generation silicon, dubbed Terminator T5, brings bandwidth and latency within spitting distance of FDR InfiniBand, and according to Chelsio, will actually outperform its IB competition on real-world HPC codes.
At the HPC Advisory Council European Conference 2012 in Hamburg, in conjunction with the International Supercomputing Conference (ISC’12), VMware’s HPC guru Josh Simons delivered a presentation of particular interest to followers of the HPC cloud space. The session tackled the million dollar HPC cloud question: “Are cloud computing and virtualization only useful for running throughput workloads or can latency-sensitive applications be run as well?”
The “Rocky” road to low-latency Ethernet.
We have developed something of a tradition at HPCwire in the weeks leading up to each year’s SC conference; we interview the chairman of the OpenFabrics Alliance (OFA). Jim Ryan of Intel has been the OFA’s chair all these years, and our annual interview with Jim was as interesting as ever.
The upcoming IEEE standard for Data Center Bridging — a.k.a. converged enhanced Ethernet — could pave the way for a new low-latency RDMA over Ethernet protocol that leaves iWARP in the dust and provides a seamless way to integrate InfiniBand into the datacenter.
