Dear users, We are aware of an issue with volume quotas in the SOF storage system, affecting GWS volumes /gws/nopw/j04/* and CEDA Archive volumes. It appears that the system is permitting writes beyond the initial volume quota, then artificially increasing the quota reported by “df -H” up to a point where writes are no longer possible. The volume quota is initially set when a volume is created; this is recorded in the JASMIN Projects Portal and available to view in the GWS Dashboard at https://mon.jasmin.ac.uk (accounts portal credentials required). This is the true volume quota: it appears that the value reported by df -H has become unreliable in these cases. The suggested course of action for GWS managers is as follows: ...

On Tuesday 4th June the GWS public web access server ( https://gws-access.jasmin.ac.uk ) will be moved to a new platform. ...

The National Centre for Atmospheric Science (NCAS) recently hosted the first-ever symposium for the early career atmospheric science community - Harmony in the Skies: Bridging Horizons in Atmospheric Science. Two CEDA graduates, Jesse Alexander and Nicola Farmer, helped organise the event, which was designed to bring staff early in their atmospheric science careers together. ...

Scientists will soon have access to triple the processing power for analysing environmental data. A £5.7 million investment for expanding the parallel compute cluster, called LOTUS , on JASMIN has been secured. The improved infrastructure allows much greater volume of parallel computing tasks - where multiple streams of data analysis tasks are undertaken at the same time - whilst reducing the time that users have to wait for their analysis to complete. Capacity will be tripled and will be available to users from Summer 2024. ...

Moving to Rocky Linux 9 For the past few weeks and months we have been preparing for a change of operating system version on JASMIN. We are now sharing our plans and progress with you, so that you are aware of the remaining changes about to happen. We can then keep you up to date with further progress as the migration gets underway. ...

CEDA, on behalf of the EO DataHub, is delighted to announce the award of significant further contracts aimed at unlocking the potential of Earth Observation (EO) data and completing the team for this landmark project. These contracts represent a significant milestone in the collaboration between commercial technology providers, application developers and data sources to deliver a first digital national EO infrastructure. ...
