Introduction to the Dardel Inauguration

Dardel is an HPE Cray EX system that is one of the flagship supercomputers of the National Academic Infrastructure for Supercomputing in Sweden (NAISS). The system is hosted by the PDC Center for High Performance Computing at the KTH Royal Institute of Technology in Stockholm and has been installed in several steps. The CPU partition was deployed in 2021, and the installation of the GPU partition, plus several significant upgrades to the first phase, were completed recently, so now the complete Dardel system is up and running. The Dardel Inauguration marks this notable occasion.
