Liste of hardware / configuration changes

Here is a changes journal of the HPC facilities. The lastest changes are on the top of the list.

2024-10-29

• Tania (process sniper) now kills greedy processes using too much MEMORY on dahu/bigfoot frontends (it used to kill processes using too much CPU, but now also monitors the MEMORY)

2024-10-22

• Eli and all instances where restarted due to a necessary firmware upgrade of all the servers' disks, recommended by Dell. The platform was stopped between 9:00 and 12:30.

2024-10-18

• Upgraded iRods clients (icommands) to 4.3.3 (Warning: configuration change is necessary and it is made automatically by the /applis/site/nix.sh script. The change occurs in the ~/.irods/irods_environment.json file where the string “PAM” should be replaced by “pam_password”)

2024-10-09

• Upgrade dahu-visu operating system to latest Debian version (Bookworm)

2024-10-08

• Added mounts ansible sync at boot time on Dahu and Bigfoot nodes
• CiGri: Bug Fix: uncleaned SQL connections

2024-10-01

• Replaced GPU #1 of bigfoot11 (Some user’s jobs failed on this GPU and DCGMI reported bad performances. Dell accorded a replacement after days of investigation)

2024-09-30

• Updated admission rules on Dahu: automatic redirection of “ljc” jobs to the long queue
• Updated admission rules on Bigfoot: prevent submissions on the devel nodes with full (/gpu=1) gpu

2024-09-09

• Upgraded OAR3 on dahu-oar3 with experimental packages 3.0.0dev14 (fixes scheduling issues, api compatability with oar2/cigri3.2 and performance issues)

2024-09-05

• Upgraded OS of Killeen, the grid server
• Upgraded CiGri to version 3.2: you have now support of OAR3 clusters (dahu-oar3 for instance) and a new efficient “temporal_grouping” option, and many bug fixed. More informations here: https://github.com/oar-team/cigri/blob/3.2/CHANGELOG.md and Here (for OAR3, you have to set up a JWT token; check the gridtoken command)
• Security updates of OS of the Luke frontend
• Security updates of OS of the Dahu frontend

2024-08-20

• Fixed Apptainer version to 1.3.2 and Singularity link to this version of Apptainer on all Dahu/Bigfoot nodes and frontends

2024-07-23

• Changed CMOS battery of a Mantis node during vetntitest service interruption

2024-06-13

• Dahu-oar3: fixed Energy-saving and scheduling

2024-05-30

• Updated and restarted Eli and all Elastic/Open-search instances

2024-04-22

• Bigfoot: Continued systemd OAR job manager adaptations : fixed Suspecting bigfoot-gh1 with users having a “-” in their login and confined GPU devices into the systemd slice

2024-04-15

• Bigfoot: OAR job manager has been modified to be able to manage the jobs with systemd on some particular nodes (as cgroupsv2 are required for bigfoot-gh1 to work properly) https://github.com/oar-team/oar3/commit/ecd174eb9

2024-04-12

• Bigfoot:
  • Doc update for AMD GPUS (rocm nix packages upgrade)

2024-04-10

• Bigfoot:
  • Upgraded bigfoot-gh1 kernel to 6.5.0-1014 and nvidia drivers to 550 —> fixed cpuset bug, so bigfoot-gh1 is back online into OAR
  • Upgraded AMD GPU firmwares on bigfoot13 as an attempt to fix some issues with inter-gpus communications
• Nix: added support for aarch64 (ARM64) architecture into /applis/site/nix.sh

2024-03-29

• Mantis:
  • fixed webdav protocol (https://mantis.univ-grenoble-alpes.fr/davrods)
  • !! The --ttl option of iinit is now mandatory for auth token to be available more than 1 hour !! Documentation has been updated accordingly: https://gricad-doc.univ-grenoble-alpes.fr/hpc/data_management/mantis/#authentification

2024-03-25

• Dahu and Bigfoot nodes:
  • Added packages (deps of apptainer): squashfuse, fuse2fs, gocryptfs
  • singularity is now a symbolic link to apptainer

2024-03-21

• Added a new queue long for jobs walltime between 48h and 160h on the Dahu cluster with a high priority on 2 nodes (dahu106 and dahu107, tagged with the long=YES OAR property)

2024-03-20

• Installed a new bigfoot-gh1 node: it’s an experimental node containing an Nvidia Grace-Hopper GH200 motherboard (72 cores ARM64 Grace + Hopper GPU). As the node is still unstable, it’s often in the “drain” mode. When not drained, you can submit jobs with the -t gh type from the bigfoot frontend.
