JASMIN login services are available - issue resolvedPosted on February 28, 2023 (Last modified on October 19, 2023) • 1 min read • 137 words
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
