We have scheduled a regular maintenance for all the clusters in our supercluster infrastructure on Tuesday, Feb 12th from 9:00 am to 5:00 pm. We are in need of taking this downtime to address some stability issues with our job scheduler which has impacted our users.

User logins and access to the data on the cluster filesystems will be blocked. Job scheduler reservations will be put in place such that there will not be any jobs running in the cluster queues for the duration of the downtime. If you are submitting jobs to your clusters before the downtime make sure you request proper wallclock time such that your job will finish before 9:00 am on Feb 12th or else your job will stay queued until after the downtime and then starts to run. User access to the data transfer node will also be turned off.

All the clusters in our supercluster including Alsacc, ARES, Baldur, Cumulus, Explorer, Hbar, JBEI, JCAP, Lawrencium (Lr1, Lr2 & Lr3 nodes) with Co2seq, Matgen, Ganita, Nanotheory, Esd1, Esd2 condos, MHG, Musigny, Nano, Natgas, Voltaire, Vulcan & Yquem all are affected by this downtime. We request all our users to save their work and close their login shell before 9:00 am on Feb 12th.

We apologize for any inconvenience. After the downtime all cluster services will be restored as before. Email us at [email protected] if you have any questions or concerns.
