- 11.15: meltdown and spectre – implications, experiences and reactions
There has been much discussion on the HPC-SIG list about the recent meltdown and spectre security flaws, and what, if any, the implications are for security and performance on an HPC cluster. This session was an informal discussion on how different sites have reacted to these flaws.

- 13.45: Cliff Addison, Liverpool: Introducing Barkla – a hybrid HPC solution
In 2017, Liverpool went to tender for a £1.2M HPC system. A hybrid service with cloud or HPCaaS alongside local hardware was highly desired. The winning bid from Dell-Alces, with some seed money from AWS, is a 100 node system based around 40 core Skylake processors and 100 gbps Omni Path using a software stack that can be replicated easily and cheaply on the cloud. Whilst not yet fully operational, things are progressing fairly smoothly and Liverpool have identified several pathfinder groups within the University who want to explore cloud computing more fully.
