Podcast: Intel Omni-Path adds Performance and Scalalability

Scott Misage, Intel

In this Chip Chat podcast, Scott Misage from Intel provides update on the Intel Omni-Path Architecture (Intel OPA).

Intel OPA, part of Intel Scalable System Framework, is a high-performance fabric enabling the responsiveness, throughput, and scalability required by today’s and tomorrow’s most-demanding high performance computing workloads. In this interview, Misage talks about market uptake in Intel OPA’s first year of availability, reports on some of the first HPC deployments using the Intel Xeon Scalable platform and Intel OPA, and gives a sneak peek of what Intel OPA will be talking about at SC17.”

Today’s rapid advances in processor and storage performance provide new opportunities for every organization that relies on high performance computing. Yet an HPC cluster is only as powerful as its weakest link. Compute, storage, and networking resources must be balanced to avoid bottlenecks that bring down the capability of the entire cluster. Intel OPA answers this challenge by providing a major leap forward in fabric performance, scalability, and cost-efficiency.

Intel OPA builds on the proven advances provided by Intel True Scale Fabric, increasing link bandwidth and integrating new open source and Aries* fabric technologies. Optimized protocols provide low latency that stays low even at extreme scale. The optimizations also provide fast and efficient file system throughput, high packet reliability, and low deterministic latency for high priority communications. Advanced traffic shaping features extend these advantages to deliver even higher levels of performance, scalability, and resiliency.

According to Misage, Intel OPA offers scalability and cost advantages that will increase with every new Intel-based platform generation. Today’s family of 24- and 48-port edge switches and 192- and 768-port director-class switches are based on new 48-port switch silicon. These high port densities can reduce infrastructure requirements compared with leading InfiniBand solutions.
