C3SE is a centre for scientific and technical computing at Chalmers University of Technology in Gothenburg Sweden. C3SE is one of six centers in the national metacenter Swedish National Infrastructure for Computing

Current systems

  • PC-cluster Hebbe for national and local users.
  • PC-cluster Glenn for local users.

C3SE is also part of SNIC Science Cloud and Swestore

Full system stop on the 26th of June

On Tuesday 26th of June, starting at 08:00 Hebbe, Glenn, the centre storage and all other resources at C3SE will be stopped.

The main reason for the stop is statutory maintenance of the power distribution infrastructure in the building housing the C3SE computer room. No users will be allowed to be logged in on Glenn or Hebbe, and no jobs will be allowed to run during/over the stop.

The last item implies that jobs might get held from starting up to a week earlier, i.e. from 08:00 on June 19th! (Adjust your job-length so that jobs will finish before 08:00 on June 26th, and they should start.)

The stop is expected to last one day.
