User Survey - ARCHER2 Evaluation Activity
UKRI has commissioned London Economics to undertake a socio-economic impact assessment of ARCHER2. The outcomes of this research will help evidence the benefits ARCHER2 brings to the academic and wider HPC community.
Your input to this study is fundamental to ensuring the study captures the importance of ARCHER2 and to help make future funding cases. We ask you take some time to complete this survey.
This survey will be open for 5 weeks from the 16th April 2025 to the 21st May 2025.
Please do complete the survey.
Spring 2025 UKRI Access to HPC Call open
Deadline: 22 May 2025 4:00pm UK time
Towards Safe and Fearless Lossy Compression of Weather and Climate Model Data
CONTINENTS webinar on Wednesday the 28th of May
The International Collaboration Towards Net Zero Computational Modelling and Simulation (CONTINENTS), is hosting its next webinar on Wednesday the 28th of May at 16h UK time, which will be delivered by Juniper Tyree (INAR, University of Helsinki), with the title: “Towards Safe and Fearless Lossy Compression of Weather and Climate Model Data”.
The abstract, further details, and calendar invite can be found on the website
There is no registration needed, please re-share this event with your contacts.
ARCHER2 Capability Days: 17-19 June 2025
The fourth ARCHER2 Capability Days session will run from 17-19 June 2025. ARCHER2 Capability Days are a mechanism to allow users to run large scale tests on the system free of charge. The motivations behind Capability Days are:
- Enhancing world-leading science from ARCHER2 by enabling modelling and simulation at scales that are not otherwise possible.
- Enabling capability use cases that are not possible on other UK HPC services.
- Providing a facility that can be used to test scaling to help prepare software and communities for future exascale resources.
Capability Days are made up of two parts:
- 0800-2000 BST, 17 June 2025 - pre-Capability Days session (pre-capabilityday QoS) to allow users to test scaling and job setup ahead of full Capability Day
- Supports jobs 256-1024 nodes, 20 min maximum run time
- Jobs are uncharged
- 2000 BST, 17 June - 1400 BST, 19 June 2025 - Capability Days session (capabilityday QoS)
- Supports jobs 512-4096 nodes, 1 hour maximum run time
- Jobs are uncharged
Advanced Computing Facility (ACF) Power Outage: Friday 29th August - Monday 15th September
Due to a significant Health and Safety risk, associated with our power supply to the site, that requires action at the ACF, there will be a full power outage to the site from Friday 29th August - Monday 15th September. Specialised external contractors will be working on a 24/7 basis for the outage period replacing switchgear.
ARCHER2 User Impact
ARCHER2 will be completely powered off for the duration of this period.
Users will not be able to connect to ARCHER2 and will not be able to access data on any of the ARCHER2 file systems. The system will be drained of jobs ahead of the power outage and jobs will not run during this period. Any queued jobs will remain in the queue during the outage and jobs will start once the service is returned.
SAFE and the ARCHER2 website will be available during the outage period so users can continue to contact us and we will be providing updates during the outage on the Status page.
We will notify users once the service is available and we expect this to be on Monday 15th September.
We apologise for the inconvenience of this essential outage. Please contact support@archer2.ac.uk if you have any questions.
Recently added known issues
The “Known Issues” page of the ARCHER2 Documentation https://docs.archer2.ac.uk/known-issues/ lists all current open known issues including a description of the issue, its symptoms and any work-arounds.
No recent issues.
