Decommisioned CoolMUC-2
End of Life
After 9 years of operation the hardware of CoolMUC-2 can no longer offer reliable service. The system is targeted to be turned off latest Friday 13.12.2024. This will also affect all housing systems attached to CoolMUC-2. Due to network degradation we can only support single node jobs on a best-effort basis until then. In case of further hardware problems, the shutdown date might be much earlier.
