The Zettascale Lab will investigate multi-vendor, low-latency Ethernet for high-performance computing solutions. We will benchmark a diversity of high-performance computing applications at a range of scales, comparing performance against the typical low-latency fabrics deployed today. This work will show where Ethernet sits in the high-performance computing ecosystem. It will inform future research into which performance characteristics need to be developed for different types of applications.
The Zettascale Lab will also investigate software-defined Ethernet technologies for high-performance computing, leveraging solutions such as P4®, a data-plane programming language which will potentially allow the network to be tuned to the precise needs of the application.
