This is the workbench of the Institute for Material Simulation. It is intended to be a common source of information for the members of the Institute, Scientists, students and others.

This is a working site and will change and grow.


The IT - Incidents and Maintenance

WW8Cloud 4. April. 2019, 15:00

The failures in our Cloud-system have been identified. A bigger update- and migration-process has been necessary.

During this process the cloud has been moved to its own separate server. WW8Cloud

We recommend switching all configurations where you use our WW8Cloud to this new server.

There still are some problems, but we will solve them in the days ahead.

WW8Cloud 29. March. 2019, 11:00

Our Old Cloud server WW8Cloud) is not responding any more.

No Login possible.

Calendar and File-sharing will be not available for an undetermined period (I don't know)

No data is lost (not now).

Maintenance SimLab 20. Feb. 2019, 15:00

Our git-repository-server ( will be offline during a bigger update and maintenance period on Wednesday the 20. Feb. 2019.

Data synchronized during the update process could be lost.

Maintenance successful - ηὕρηκα

  1. New certificate employed. Now external use will be much easier.
  2. Database updated.

historic machines

For running old simulations we keep some old systems. They can be activated instead of the current simulation nodes.

sim32 cl1 \~8 cores, \~4 GB RAMFedora 32 (2021) \~ maintenance
sim30 cl1 \~8 cores, \~4 GB RAMFedora 30 (2020) \~ on demand

If you have demand for some special configurations, more cores more memory on one of the simulation nodes, or you want to try some historic machines just ask the IT to reconfigure the systems
