Modification of STORE access terms
[English version below]
Hello,
With the arrival of the H100 extension, a renewal of the storage spaces is also planned for the summer. The storage volume (in bytes) of WORK spaces will be increased on this occasion. In return, access to the STORE will have to be adapted. In particular, read and write access to the STORE will no longer be possible from the compute nodes. It will be maintained on the login nodes and on the "prepost", "visu", "compil" and "archive" partitions.
This change will take effect after the maintenance scheduled for Tuesday, July 9, 2024. We invite you to modify your jobs now if you access the STORE space directly from the compute nodes. To guide you, examples have been added at the end of our documentation on multi-step jobs: http://www.idris.fr/eng/jean-zay/cpu/jean-zay-cpu-exec_cascade-eng.html
As a reminder, the STORE is a space dedicated to the long-term storage of archived data. For now, the STORE provides redundant data storage on both rotating disks and magnetic tapes. The presence of data on rotating disks means that it can be read and written relatively quickly. In the future, data may only be stored on magnetic tape (with two copies on different tapes to maintain data redundancy), which would severely degrade the performance of your calculations when accessing the STORE directly.
Please do not hesitate to contact IDRIS support (assist@idris.fr) if you need any assistance.
Best regards,
The IDRIS support team
