Retired systems

MACH-2

MACH-2 was a massively parallel shared memory supercomputer that implemented a global shared memory model. It was installed in 2017 and was operated by the Johannes Kepler University (JKU) Linz until 2023.

VSC-3

VSC-3 retired in May 2021. Its extension VSC-3+ went out of service in October 2022.

VSC-3 was a throughput-oriented general-purpose Linux cluster with approximately 2800 compute nodes and a few special-purpose nodes such as GPUs. It was renowned for its innovative oil cooling and unparallelled energy efficiency. It ranked 86th in the November 2014 TOP500 list. VSC-3 was installed in summer 2014 at the Arsenal TU building in Vienna and got a significant extension called VSC-3+ in June 2018. The main oil-cooled nodes had 2 processors each (Intel Xeon E5-2650v2, 8 cores) and 64GB RAM (some nodes with 128/256GB), connected via dual-rail QDR Infiniband. The extension consisted of nodes with faster CPUs, several GPU partitions, and a high-memory partition aimed at Bioinformatics applications.

VSC-2

VSC-2 went out of service by the end of December 2018.

VSC-2 was installed in May 2011 at the Arsenal TU building in Vienna and ranked 71st in the June 2011 TOP500 List. It consisted of 1314 nodes, each with 2 processors (AMD Opteron 6132 HE, 8 cores) and 32GB RAM, connected via QDR InfiniBand.

VSC-1

VSC-1 went out of service by the end of March 2015.

VSC-1 was set up in 2009 with in the Freihaus building of TU Wien and ranked 156th in the November 2009 TOP500 list. It consisted of 476 nodes with 2 processors each (Intel Xeon X5550, 4 cores) and 24GB RAM, connected via QDR Infiniband.
