Suitable use

Throughput clusters, an amalgamation of older point-of-presence and throughput clusters, suitable for serial applications, and small-scale low latency demanding parallel MPI applications.

Cluster is back up after the Sunday power outage. Any jobs that were running on the bul nodes at the time have been lost.

Kraken, goblin and monk are partially or fully down after a suspected power outage on Sunday. We are working to recover them.

Starting yesterday afternoon, /global/b has returned to service on all Sharcnet clusters. We apologize for the extended outage, and believe that there was no loss of data. In recognition of how this outage was disruptive to 1/3 of users, affected users will be given higher inter-cluster fairshare/priority.

If you notice problems, please report via the ticket system: help@sharcnet.ca or https://www.sharcnet.ca/my/problems/submit

Several UWO-based systems may have limited service due to cooling failures, including some global work systems, goblin and kraken. We hope to keep service disruption to a minimum.

Our apologies, but some of the “bul” nodes have been shut down due to more cooling problems in the data centre. Jobs on those nodes have been lost.
