Service Desk holiday Monday 6th May
The ARCHER2 Service desk will be closed on Monday 6th May 2024.
It will reopen as normal on Tuesday 7th May at 08:00.
ARCHER2 maintenance
There will be a full ARCHER2 maintenance on Wednesday 8th May from 0900 - 2100. This is to allow an essential system update to take place.
During this maintenance, users will not be able to connect to the login nodes, jobs will not run and users will be unable to access data.
We will notify users once ARCHER2 is returned to service.
HPC Summer School
Apply for the High Performance Computing Summer School at EPCC in Edinburgh! This 2-week long programme, taking place at EPCC in Edinburgh University, Scotland from 22nd June, will give around a dozen undergraduate students at UK universities the opportunity to learn and practise HPC technologies. Travel, accommodation and subsistence will all be covered.
2024 Educational Award For Outstanding Contribution to Computational Science Education
The ACM SIGHPC Education Chapter is seeking nominations for candidates for the 2024 Educational Award For Outstanding Contribution to Computational Science Education. We are seeking candidates who have led projects or programs that have made significant contributions to computational science education defined broadly to include all disciplines and all education levels.
The award will be presented at SC24. The recipient will receive a $2,000 cash award and travel support to attend the SC24 conference. Nominations will include a statement endorsing the nominee, and up to three letters of endorsement. Applications are due by Friday June 28, 2024, by end of day anywhere on earth. The chapter will choose up to one award winner and up to two honorable mentions.

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.
- When close to storage quota, jobs may slow down or produce corrupted files (Added: 2024-02-27)
For situations where users are close to user or project quotas on work (Lustre) file systems we have seen cases of the following behaviour:
- Jobs run very slowly as IO slows down
- IO calls seem to complete successfully but not all data is written (so output is corrupted)
- No “disk quota exceeded” error is seen
If you see these symptoms: slower than expected performance, data corruption; then you should check if you are close to your storage quota (either user or project quota). If you are, you may be experiencing this issue. Either remove data to free up space or request more storage quota.
