The Zettascale Lab will investigate multi-vendor, low-latency Ethernet for high performance computing solutions. We will benchmark a diversity of HPC 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 HPC 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 HPC, 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.
