    MGHPCC will be performing power upgrades on Pod 8A in order to increase density and allow more nodes to be added in that Pod's rows.  Similar to the May 13th work, this means that we will be idling half the nodes in 8A on two dates: June 17 and June 24th.

    These are all day events, meaning that the nodes in question will not be available for the 24 hours of that day.  This is being accomplished via reservations. So no jobs will be canceled but nodes will be drained and users may notice that their jobs may pend longer than normal as the scheduler idles these nodes.

    Where possible, please use or include other partitions in your job scripts and plan accordingly for any new or long-running jobs during that period: https://docs.rc.fas.harvard.edu/kb/running-jobs/#Slurm_partitions

    This affects the Cannon cluster. FASSE is not affected.

    Dear All,

    NESE Tape system upgrade is currently in progress. While IBM hardware
    team works on TS4500 library tape frame expansion and IBM software team
    works on ESS and Archive software and firmware upgrades, the work
    progress has been slowed down due to unforeseen hardware issues.We now expect to bring the tape service back into production this Monday
    morning. We apologize for any inconvenience caused by the delay.

    DOWNTIME COMPLETE

    The annual multi-day power downtime at MGHPCC (https://www.rc.fas.harvard.edu/blog/2024-mghpcc-power-downtime/) is complete (with any exceptions noted below). Normal service resumes today (Friday May 24th) at 5pm.

    The cluster has been updated to Rocky Linux 8.9. Several network, InfiniBand, computer, and storage firmware updates were installed. Available security updates were also installed.

    CANNON NODES

    More than 90% of nodes are up and all partitions are enabled. If your specialty partition has a downed node, we will attend to this on Tuesday.

    FASSE OOD

    Some updates are still propagating. If your FASSE Open OnDemand/VDI session does not work initially, please wait or retry your job/session.

    POST-DOWNTIME SUPPORT

    If you have any further concerns or unanswered questions please submit a help ticket (https://portal.rc.fas.harvard.edu/rcrt/submit_ticket) and we will do our best to respond quickly. Please bear in mind it is a long weekend, so lingering issues may not be dealt with until Tuesday.

    Also, have a good long Memorial Day weekend!

    Thanks,

    The 2024 MGHPCC data center annual power downtime will take place May 21-24, 2024.

    We will begin our shutdown on Tuesday May 21st and expect a return to service by 5PM Friday May 24th.

    - Jobs: Please plan ahead as all still running jobs on the morning of May 21st will be stopped and canceled and will need to be resubmitted after the downtime. Pending jobs will remain in the queue until the cluster returns to regular service on May 24th.

    - Access: The cluster, scheduler, login, and OoD nodes will be unavailable for the duration of the downtime. New lab and account requests should wait until after the downtime.

    - Storage: All Holyoke storage will be powered down and unavailable for the duration of the downtime. Boston storage will remain online, but your ability to access it may be impacted and network changes may briefly affect its availability.

    Further details, an explanation for this year's change in scheduling, a visual timeline, and a list of maintenance tasks overview can be found at:

    https://www.rc.fas.harvard.edu/blog/2024-mghpcc-power-downtime/

    Progress of the downtime will be posted here on our status page during the event. Note that you can subscribe to receive updates as they happen. Click Get Updates in the upper right.

    MAJOR TASK OVERVIEW

    • OS upgrade to Rocky 8.9 - Point upgrade, no code rebuilds will be required. Switch from system OFED to Mellanox OFED on nodes for improved performance

    • Infiniband (network) upgrades

    • BIOS updates (various)

    • Storage firmware updates

    • Network Maintenance

    • Decommission old nodes (targets contacted)

    • Additional minor one-off updates and maintenance (cable swap, reboots, etc.)

    We are still unable to resolve the issue with these nodes and are working with the facility, networking, and our staff to find a solution. The affected partitions (noted in previous update below) will be resource-constrained and continue to be slow or unable to queue new jobs.


    If you are using a partition that cannot queue new jobs, please consider adding additional partitions to your job: https://docs.rc.fas.harvard.edu/kb/running-jobs/#Slurm_partitions

    Also, a reminder that the data center power downtime will begin Tuesday morning. So any new jobs scheduled for more than 3 days will not complete: https://www.rc.fas.harvard.edu/blog/2024-mghpcc-power-downtime/

    holynfs01 has experienced a hardware failure. We have set all shares to read-only mode while we retrieve data from this server.

    If your group requires a writable space in the interim, please reach out and we will set one up for you or use scratch space for now.

    This only affects a handful of NCF shares, most inactive. But we are notifying all to cast a wide net.
