MIDAS Open version 202007 released More UK weather station data added
Last year the Met Office released the “ MIDAS Open ” dataset, a publically available version of the popular, but restricted, Met Office Integrated Data Archive System ( MIDAS ) Land and Marine Surface Stations dataset. Thanks to the efforts of the MIDAS Open team at the Met Office we’ve now published an updated version of MIDAS Open, bringing in new data for 2019 and updates for some existing years too. Though aimed at being of interest to everyone, we anticipate these new data will be particularly useful for service providers or members of the public who have previously been unable to use the restricted MIDAS dataset.

LOTUS/SLURM issues update
Dear all,
As you know we have recently seen some problems with the SLURM scheduler for the LOTUS batch processing cluster, with jobs remaining in the pending state for much longer than normal. This issue has been and remains a top priority for the JASMIN team to resolve. Here’s the current state of affairs:
• Today (Monday 5 Oct)
o Fair-share configuration has been adjusted to attempt to lower the priority of very large/long-running jobs (which were causing sections of the cluster to become blocked)
o An even mix of user ids is now being seen with running and pending jobs, implying that jobs are now starting to flow more normally, without being dominated by any one user.
o A fix to a storage client has been rolled out to some parts of JASMIN which fixes a write issue for some users (NB not necessarily related to scheduling issues)
