Enabling essential climate science research
Climate Change is a defining issue of our time. The UK’s top 10 warmest years have all occurred since 2002, and July 2019 saw the UK’s hottest ever recorded temperature (38.7 °C). Whilst many are enjoying the unusually non-rainy British weather, it doesn’t come without costs. Extreme weather events, such as heatwaves and flash flooding, are expected to increase in severity and frequency as our climate continues to change. Extreme weather can adversely affect the way we live our lives. Loss of food production, damaging wildlife habitats, and endangering human life are just a few impacts associated with climate change. Predicting global climate change is complex and requires vast amounts of data processing capabilities. Steps must be taken to improve the accuracy of future climate models. That’s where JASMIN - a data intensive supercomputer - comes in. ...

Update on JASMIN Maintenance 21 April 2020
Following scheduled maintenance on parts of the JASMIN system yesterday, please note the following:
Servers were patched and rebooted where necessary to apply important updates. There were nearly double the number of hosts to update this time, as we transition from RHEL6 to CentOS7 operating systems, so this took longer than usual.

GWS (/gws/nopw/j04/) performance issue
Dear JASMIN users,
We are aware that users are experiencing difficulties with performance and access to some resources on JASMIN at present. This is due to a problem with one of the storage servers.
This will affect the performance of Group Workspaces under the path /gws/nopw/j04 - we believe that small files (<64KB) and symbolic links are more likely to be affected.

JASMIN Migration to CentOS7 & LSF replacement with SLURM UPDATE 5
We are pleased to announce that the two new scientific analysis servers, “ sci1.jasmin.ac.uk ” and “ sci2.jasmin.ac.uk ” are now available with the CentOS7 systems and the new software environments1. These two VMs are available for testing and they are listed in the table of available “sci” servers shown when you log in to any of the login servers. [Please note that the domain name of the new “sci” servers has changed from “ .ceda.ac.uk” to “ .jasmin.ac.uk ”].

COVID-19 lockdown- impact on CEDA and JASMIN operations
As we are sure you are already aware, the latest government restrictions on travel mean that any issues requiring physical intervention to the JASMIN infrastructure (e.g. a visit to the machine room by a member of the technical team) could now take up to a day or more to resolve. Strict procedures are in place to keep our key members of staff safe whilst they visit the RAL site - but these procedures take time to organise, hence the anticipated delays. ...
