Here in EPCC we lead a work package of the VESTEC EU FET project which is working on the fusion of real-time data and HPC for urgent decision-making for disaster response. While HPC has a long history of simulating disasters, what’s missing to support emergency, urgent, decision-making is fast, real-time acquisition of data and the ability to guarantee time constraints.

In this blog post I consider how we (as the UK HPC community) could create a community HPC technical knowledge base that would allow us to share and reuse useful technical information. Much of these thoughts came out of discussions at the HPC Champions meeting that took place on 16 September 2019 alongside the UK RSE Conference 2019 in Birmingham, UK along with subsequent discussions at the monthly HPC RSE calls.

The class of 2019 was the eighteenth cohort of EPCC MSc students and the first to be based at the Bayes Centre home. Our new surroundings have been immensely beneficial to the student experience, with the student desk space quite literally on the doorstep of staff offices and plenty of space to breakout for group study. Despite 2018/19 being our largest MSc intake in terms of entrants to that point, it was an incredibly cohesive group.

After four years of hard work, the NEXTGenIO project has now come to an end. It has been an extremely enjoyable and successful collaboration with a dedicated group of HPC users, software and tools developers, and hardware providers from across Europe.

From 10–13 October, EPCC were exhibitors at New Scientist Live 2019. Various members of EPCC attended – as well as myself, there were Outreach regulars Gordon Gibb, Oliver Brown, Juan Rodriguez Herrera, and Ben Morse, as well as relative newbies Darren White, Spyro Nita, and Evgenij Belikov.

14 November, Bayes Centre, Edinburgh
Here at EPCC we are gearing up for the HPC-Europa3 workshop for SMEs. This event will explain the funding available to support visits by EU experts in high performance computing to Scottish/UK SMEs (and vice versa), and also for access to major computing resources for large-scale simulations and/or data analytics.

In October I ran an online training course teaching current and potential ARCHER users how to run LAMMPS. LAMMPS is a widely-used open-source molecular dynamics (MD) software developed at the National Sandia Laboratories, and is optimised to run well on HPC facilities. It consistently ranks in the top 10 most used programs on ARCHER. Although the course was run on ARCHER and with ARCHER users in mind, I tried to teach users how to use LAMMPS on any platform.

Blog post updated 8th November 2019 to add Figure 6 highlighting PMDK vs fsdax performance for a range of node counts.
Following on from the recent blog post on our initial performance experiences when using byte-addressable persistent memory (B-APM) in the form of Intel's Optane DCPMM memory modules for data storage and access within compute nodes, we have been exploring performance and programming such memory beyond simple filesystem functionality.
For our previous performance results we used what is known as a fsdax (Filesystem Direct Access) filesystem, which enables bypassing the operating system (O/S) page cache and associated extra memory copies for I/O operations. We were using an ext4 filesystem on fsdax, although ext2 and xfs filesystems are also supported.

Set in the heart of the Scottish Borders and home to Melrose Abbey and Melrose RFC, a visit to Melrose is always a pleasure. Organised by St Mary's School, Bang Goes the Borders (21st September 2019) is a science festival aimed at families. Entirely free, the festival has loads of workshops and drop in sessions. The ARCHER team and Wee Archie were sat alongside workshops and activities around lego robots, apple juice making, plaque busting, bees, birds, and much, much more.
