Thursday 28 March 08:00 EET (09:00 CET)

• LUMI Cooling Distribution Unit flush

  • LUMI cooling needs maintenance and this requires an estimated 2-day downtime per cooling group in addition of the first one which needs a longer maintenance (see calendar below). While cooling groups are under maintenance, 3 compute cabinets are out of production which will cause reduced computing capacity in some of the partitions.
  • The maintenance will start on Wednesday 3 April until Sunday 21 April.
  • The following partitions will have reduced capacity during this period of time (1 cabinet includes 124 nodes):
    • Wednesday 3 April to Sunday 7 April
      • ju-standard-g: 2 cabinets
      • standard-g: 1 cabinet
    • Monday 8 April to Tuesday 9 April
      • standard-g: 3 cabinets
    • Wednesday 10 April to Thursday 11 April
      • standard-g: 3 cabinets
    • Friday 12 April until end of lustre maintenance break (see below)
      • standard-g: 3 cabinets
