Sun 30 Jun 30 2019 The SOSCIP BGQ and P7 systems were decommissioned on June 30th, 2019. The BGQdev front end node and storage are still available.

Wed 19 Jun 2018, 1:20:00 PM: The BGQ is back online.

Wed 19 Jun 2018, 10:00:00 AM: The BGQ is still down, the SOSCIP GPU nodes should be back up.

Wed 19 Jun 2018, 1:40:00 AM: There was an issue with the SOSCIP BGQ and GPU Cluster last night about 1:42am, probably a power fluctuation that took it down.

Wed 12 Jun 2019, 3:30 AM - 7:40 AM Intermittent system issues on Niagara's project and scratch as the file number limit was reached. We increased the number of files allowed in total on the file system.

Thu 30 May 2019, 11:00:00 PM: Niagara maintenance finished. Some action on the part of users will be required when they first connect again to a Niagara login nodes or datamovers. This is due to the security upgrade of the Niagara cluster, which is now in line with currently accepted best practices. The details of the required actions can be found on the SSH Changes in May 2019 wiki page.

Fri 5 Apr 2019 Software updates on Niagara: The default CCEnv software stack now uses avx512 on Niagara, and there is now a NiaEnv/2019b stack ("epoch").

Thu 4 Apr 2019 The 2019 compute and storage allocations have taken effect on Niagara.
