Description
An HTC cluster using HTCondor has been set up at Bonn University in 2017/2018.
All infrastructure is fully puppetised, including the HTCondor configuration.
Both interactive and batch jobs are run inside Singularity containers, and users only have to choose the desired OS via a job parameter from an offered collection of container images without setting up or building a container themselves.
The container images are rebuilt daily and are provided by a CernVM filesystem (CVMFS) along with various software packages. The data to be analysed is stored on a CephFS file system.
This talk presents the successful migration from a "classic" PBS cluster setup with separate login nodes providing an environment similar to the batch environment, causing many regular admin headaches, to a modern and flexible, HTCondor-based system offering the users several different environments both for interactive and batch usage. Both the successes and the several pitfalls and issues which were encountered will be discussed.
