JASMIN login services are available - issue resolved

Dear JASMIN user,

 

We believe that the recent issue that affected the PURE storage system that hosts the home users directories and some small-files group workspaces is now resolved and JASMIN login services are operational.

 

The PURE storage system that hosts the home users directories exhibited issues related to parallel-write/read locks with some impacts to system performance as a whole. The relevant processes were identified and modified to avoid this happening.

 

Users are reminded that processes which require parallel write access to a file, particularly at scale (for example, if many LOTUS jobs need to update the same file), should make use of PFS storage such as the /work/scratch-pw[2,3] volumes, and should be tested before large-scale execution. 

Please see https://help.jasmin.ac.uk/article/176-storage for information about types and location of storage.

 

Thank you for your patience and cooperation 

JASMIN team
