The Vagn-Ekman Case Study at SNIC-NSC
Johan Raber, Lundqvist, Per, Bengt L Persson · Zenodo (CERN European Organization for Nuclear Research) · 2012
Vagn-Ekman is a dual cluster setup with specialized functionality of the two parts. Ekman is a large compute cluster located in Stockholm, and Vagn is a storage and post-processing cluster located at NSC in Linköping. To an extent, the Vagn and Ekman clusters resemble future PRACE operations in the sense that from a large data production facility there will be a need to conveniently transfer the produced data to the researchers, potentially scattered across Europe, in a safe manner with respect to data integrity. The experiences and tools developed during the Vagn-Ekman project can serve as an example for how this data flow can be carried out.
