We are facing some difficulties with the Stallo file system, and thus will delay access for users until this has been fixed. Possible tradeoff will be days in January with the old friendly gigant.
Access to Stallo has now been closed temporarily due to power testing tomorrow morning 07:00-09:00 in the housing building of Stallo. We will try to put it back into service a.s.a.p after tests have been run.
Note that probabel end-of life for the old monster will be Jan. 04th 2021.
Stallo downtime on Dec 16th is cancelled. Instead downtime on Dec 29th, due to work on power infrastructure. So you can run your calculations till after Christmas without us getting in the way. Regards this a Xmas present from all of us to all of you.
We need to move oldest limps of the faltering monster. In case of trouble, we have choosen to close the machine for users during maintenance time since we may have to power down the network switches on internal network. Downtime is scheduled for 08:00-15:00.
The reported issues related to Stallo file system are resolved. We apologise for the late update.
As published on Twitter; Stallo is now down due to necessary power infrastructure work in the hosting building at UiT. Due to this, and an overall work-load and risk consideration done by the operational team for Stallo, the oldest nodes – c1-c19; i.e. the 16 core nodes, will not be turned on again tomorrow. This includes the high mem partition on Stallo. Thus Stallo will be reduced by approximately 4800 cores from now. Expected downtime is 24 hrs from 12 today. from noon tomorrow only the 20 core nodes will be up, a total of approx 10k cores running out dec. 20.
Stallo is now up and running again. Unfortunately, the old lad lost two racks during hibernation. We are looking into it and will report when things are up and ok again. Please look into jobs that have been restarted and report back if they produce no output.
We need to take down Stallo for work on building infrastructure. Downtime will be from Tue June 2nd 12:00 until no later than Thu June 4th 12:00. We apologize for the inconvenience.
Due to the national and local measures to inhibit spreading of the non-digital virus COVID-19, HPC@UiT will have lower capacity to do on-site maintenance on Fram. You might expect longer response time on reported issues and hardware failure.
Please use version 5.4.4-intel-2018a instead.
