To keep the ARCHER2 National HPC Service running around the clock requires specialised staff, covering everything from the Service Desk and science support, through to hardware maintenance and data-centre hosting, alongside third-party suppliers for power, networking, accommodation, and so on. Coordinating these elements is a complex task, even in normal...

The ARCHER2 full system was opened to users on the morning of Monday 22 November 2022. In this blog post I introduce the full system and its capabilities, and look forward to additional developments on the service in the future. TL;DR For those who just want to get stuck in...

EPCC are delighted to be able to announce that we have passed our ISO 9001 Quality and 27001 Information Security external audits with flying colours. We put the highest importance on service delivery and secure handling of customer data throughout the year. Despite this, it is still a nerve racking...

In spring 2020 EPCC became one of the very few organisations in the UK to become accredited data processors under the Digital Economy Act (DEA), one of exactly 8 accredited data processors in the UK! This was for the hosting and technical management of the National Safe Haven. EPCC is...

We have all become accustomed to having a wide range of pre and post-processing tools available to us on our laptops, which can make working on the login nodes of a large HPC system such as ARCHER2 rather inconvenient if your favourite tools aren’t available. On something fairly standard like...

This blog post follows on from “HPC Containers?”, which showed how to run a containerized GROMACS application across multiple compute nodes. The purpose of this post is to explain how that container was made. We turn now to the container factory, the environment within which containers are first created and...

Containers are a convenient means of encapsulating complex software environments, but can this convenience be realised for parallel research codes? Running such codes costs money, which means that code performance is often tuned to specific supercomputer platforms. Therefore, for containers to be useful in the world of HPC, it must...

This week the final cabinets to complete the full ARCHER2 system have arrived onsite in Edinburgh on multiple trucks. The boxes were so large that doors had to be removed. All cabinets are now safely in place, with water cooling enabled. Further work to integrate them into the system is...

An HPC service such as ARCHER2 manages thousands of user-submitted jobs per day. A scheduler is used to accept, prioritise and run this work. In order to control how jobs are scheduled all schedulers have features for defining the manner in which work is prioritised. On the ARCHER and ARCHER2...

Today saw a significant milestone in our move towards our full 23 cabinet ARCHER2 system. A small group of CSE staff gained access to the main HPE Cray EX supercomputing system today and are currently putting it through its paces. Andy, William, David, Adrian, Julien and Kevin will be testing...

The first year of the ARCHER2 service has been very challenging, mainly due to the COVID-19 pandemic. Nonetheless, we have successfully delivered a fully online training programme. Since April 2020, a total of 66 days of training were delivered under the ARCHER2 service. We have used Blackboard Collaborate software for...

ARCHER2 is funded by UKRI through two partner councils, EPSRC and NERC, who started building the case for the system back in 2016. Rebecca How from EPSRC’s Research Infrastructure team joined the ARCHER2 project in January 2019, taking over the Project Manager role for the upcoming service, while also acting...

Quite a few application codes running on ARCHER2 are implemented using both MPI and OpenMP. This introduces an extra parameter that determines performance on a given number of nodes - the number of OpenMP threads per MPI process. The optimum value depends on the application, but is also influenced by...

Back in February, I reviewed the usage of different research software on ARCHER over a large period of its life. Now we have just come to the end of the first month of charged use on the ARCHER2 4-cabinet system I thought it would be interesting to have an initial...

In the evening of March 19th 2021 a volcanic eruption started in Fagradalsfjall, Iceland. Although the episode posed no threat to aviation (no ash was produced), significant amounts of volcanic gases were (and still are being) released. Such gases can cause respiratory problems, and if the concentrations are high enough,...

With the end of the ARCHER service in January 2021, the ARCHER2 4-cabinet pilot system has now been operating as the national service for three months. A new architecture, programming environments, tools and scheduling system is a new challenge for users to experiment with and discover techniques to achieve optimal...

We recently received the main ARCHER2 hardware at the ACF and our team recorded the process of installation as this exciting new system was deployed. You’ll see large “Mountain” cabinets being deployed each of which holds 256 Compute Nodes with 128 CPU cores each as well as a number of...

It seems strange to be thinking about how to justify investment in ARCHER3 and beyond, with ARCHER2 not fully in service yet, but it is never too early to start planning this. ARCHER generated a significant amount of world-leading science and we fully anticipate ARCHER2 will as well. It is...

It’s been a busy week at the Advanced Computing Facility (ACF) with the arrival of the remaining ARCHER2 cabinets. The long journey started from the HPE Cray factory in Chippewa Falls, Wisconsin (birthtown of Seymour Cray) before arriving in Prestwick airport. It took three separate journeys of four lorries to...

Last week marked the end of the ARCHER Service after seven years. You may have heard some statistics over the last week about ARCHER but I wanted to tell you some from the helpdesk. During the lifetime of ARCHER, the User Support and Systems teams (SP) have resolved 57,489 contractual...

Now that the ARCHER service has finished, I thought it would be interesting to take a brief look at the use of different research software on the service over its lifetime. ARCHER was in service for over 7 years: from late 2013 until its shutdown in early 2021. Over the...

Back in February 2015, a little over a year after the ARCHER service began, EPCC launched an entirely new and innovative access route, for users to get time on ARCHER via a “Driving Test” The idea behind this was to help those who had never used ARCHER, or possibly any...

As the ARCHER service was switched off, our colleagues at the ACF photographed and recorded ARCHER’s final moments. With a particular thank you to Connor, Aaron, Jordan, Craig and Paul at the ACF and to Spyro for putting this video together, we give you ARCHER’s final moment. It is best...

At 8am this morning the ARCHER service was switched off. Funded by EPSRC and NERC, this sees the end of a remarkable service, a service that has acted as the UK’s National HPC Service for the last 7 years. Entering service at the end of 2013, just over 5.6 million...

We are currently in (or have recently finished, depending on when you read this) the Early Access period for the ARCHER2 service. During this period, users nominated by their peers and the ARCHER2 teams at EPCC and HPE Cray have had access to the ARCHER2 4-cabinet system. The Early User...

One of the upsides of working on the ARCHER2 CSE team is that, sometimes, one finds oneself in the interesting position of being the only user on the ARCHER2 four-cabinet system (at least the only apparent user – I’m sure that AdrianJ is lurking on one of the compute nodes...

On the 14th July 2020 the first four cabinets of ARCHER2 arrived at the ACF and over the following few days they were unpacked, moved into position, connected up and ultimately powered up ready to go. Gregor Muir was on hand, capturing the whole process in still images and timelapse...

A full week on from the 4 Cab Archer2 installation (affectionately dubbed Mini-Archer2, due to only having 18% of the full Shasta system’s 5848 compute nodes), and life is beginning to quiet down again for the temporary Summer Team at the ACF. This is now the second year that the...

Covid-19 has created significant challenges for the delivery of the new ARCHER2 system. It is therefore really exciting to see the first 4 cabinets of ARCHER2 leave Cray/HPE’s factory in Chippewa Falls, Wisconsin to begin their journey to Edinburgh. ARCHER2 will replace the current ARCHER system, a Cray XC30, as...

UKRI are having weekly meetings with the ARCHER2 providers, EPCC and Cray/HPE. We are making good progress and are still on track to start installation of some compute capacity (a pilot system) in mid-July. We are also looking at further ARCHER extensions due to the COVID-19 delay. We now expect...
