SUMMARY:Monthly maintenance October 4th, 2021 7am-11am
DESCRIPTION:\nRegular monthly maintenance will take place Monday October 4th, 2021 7-11am\nNOTICES\n\nUpdate to fairshare mechanism to help break ties within lab groups. No discernable change to the majority of cluster users. This small adjustment is weighted by a users individual usage, breaking ties internal to a group. https://docs.rc.fas.harvard.edu/kb/fairshare/#Nice ( https://docs.rc.fas.harvard.edu/kb/fairshare/#Nice )\nNew cluster hardware comes online Sept 30th, increasing overall computational power by 25%\n- new block of 18 water cooled GPU nodes, each with NVidia SXM4 (4x A100 cards)\n- new block of 36 water cooled “big mem” compute nodes, each with 2x Intel 8358 processors (64 cores total) and 512 GB of RAM\n- retirement of less-efficient gear including most AMD compute and K80 GPUs\n- gratis fairshare has been increased to 120 for all labs\nSee the blog post from Scott (or Sept 13th email) for more details: https://www.rc.fas.harvard.edu/blog/2021-cluster-upgrade/ ( https://www.rc.fas.harvard.edu/blog/2021-cluster-upgrade/ )\nHolyscratch cleanup will remove many retention exceptions - Owners of that data have been notified\nTraining sessions available: https://www.rc.fas.harvard.edu/upcoming-training/ ( https://www.rc.fas.harvard.edu/upcoming-training/ ) \nNew Storage Service Center launched FY22 (July 1st 2021).  See Billing FAQ https://www.rc.fas.harvard.edu/policy/billing-faq/ ( https://www.rc.fas.harvard.edu/policy/billing-faq/ ) and list of storage tiers https://www.rc.fas.harvard.edu/services/data-storage/ ( https://www.rc.fas.harvard.edu/services/data-storage/ ). Individual PIs will be contacted about setting up their billing.\nIf you have a 2021/2021 publication that made use of the FASRC cluster and you don't find it listed here, please do let us know: https://www.rc.fas.harvard.edu/cluster/publications/ ( https://www.rc.fas.harvard.edu/cluster/publications/ )\n\nGENERAL MAINTENANCE\n\n\n\nNCF VDI/OoD - Retire old Jupyter/Jupyterlab apps\n\nAudience: NCF VID/OpenOnDemand\nImpact: Removes old apps, existing/new apps not affected.\n\n\nhsphs10 fileserver will be decommissioned on October 1st\n\nAudience: Users of hsphs10\nImpact: Tenants have been notified, so no expected impact\n\n\nBoston and Holyoke Isilon upgrades\n\nAudience: Isilon (Tier1) shares in both data canters\nImpact: None expected. Upgrades should roll across redundant nodes with no downtime\n\n\nIQSS SID beta deployment  Deferred\n\nAudience: Beta testers\nImpact: None\n\n\nwww.rc.fas.harvard.edu and docs.rc.fas.harvard.edu upgrades\n\nAudience: Visitors to either website\nImpact: Both sites will be down for approximately 10 minutes each\n\n\n\n\nLogin node and VDI node reboots\n\nAudience: Anyone logged into a a login node or VDI/OOD node\nImpact: Login and VDI/OOD nodes will be unavailable while updating and rebooting\n\n\nScratch cleanup ( https://docs.rc.fas.harvard.edu/kb/policy-scratch/ ( https://docs.rc.fas.harvard.edu/kb/policy-scratch/ ) )\n\nAudience: Cluster users\nImpact: Files older than 90 days will be removed.\nReminder: Scratch 90-day file retention purging runs occur regularly not just during maintenance periods.\n\n\n\nThanks,\nFAS Research Computing\nhttps://www.rc.fas.harvard.edu ( https://www.rc.fas.harvard.edu )\nhttps://docs.rc.fas.harvard.edu ( https://docs.rc.fas.harvard.edu )\nhttps://status.rc.fas.harvard.edu ( https://status.rc.fas.harvard.edu )\nReminder: Scratch 90-day file retention ( https://www.rc.fas.harvard.edu/policy-scratch/ ) purging runs occur regularly not just during maintenance periods.\n\n\n\n
