Vienna Scientific Cluster is the name of a series of four supercomputer clusters at the location of the Technical University of Vienna which are used by various Austrian universities as of 2018. VSC is a joint project of the Vienna University of Technology, the University of Vienna and the University of Natural Resources and Life Sciences Vienna . While the first expansion stage VSC-1 was only available to universities in Vienna, the second and third expansion stages, VSC-2 and VSC-3, were also made available to other Austrian universities: the Technical University of Graz , the University of Graz and the University of Innsbruck . At the time of their commissioning, all four clusters were in the TOP500 list of the world's fastest supercomputers; the fourth cluster was 82nd in the world at the time of commissioning (July 2019).

VSC-1

VSC-1 was put into operation in 2009 in the Freihaus of the TU Wien in the 4th district of Vienna. It consisted of:

  • 18 racks with 436 computing nodes, each with two 4-core processors Intel Xeon X5550 and 24 GB of RAM
  • 40 computing nodes with two Intel Xeon X5650 6-core processors each
  • The networking took place via Infiniband QDR with 40 Gbps
  • With a total of 3,968 computing cores and 12.3 TB of RAM, it achieved a maximum performance of 35.5  TFLOPS and at that time was system number 156 in the TOP500 list from November 2009

VSC-2

VSC-2 was put into operation in May 2011 at the then newly founded Science Center of the Vienna University of Technology in Arsenal Vienna and consisted of:

  • 30 racks with 1,314 compute nodes, each with two 8-core processors of the type AMD Opteron 6132 and 32 GB of RAM
  • Networking took place via 80 Infiniband switches with QDR 40 Gbps
  • Water-cooled rack doors were used to support the cooling
  • The total electrical output was 420 kW
  • With a total of 20,776 Opteron cores, 42 TB of RAM and 152.9 TFLOPS, it was 238th in the Top500 in June 2013

VSC-3

VSC-3 is also housed in the Science Center in Arsenal Vienna and consists of:

  • 2,020 compute nodes each with two 8-core processors of type E5-2650 v2 and 64 to 256 GB of RAM
  • A total of 32,768 cores with a total of 130 TB of RAM and Infiniband networking
  • As of November 2014, the VSC-3 was the fastest Austrian supercomputer with 596.01 TFLOPS and took 85th place in the TOP500
  • It uses a liquid cooling system consisting of paraffin oil in which the individual computer modules are immersed in order to efficiently transport away the heat loss . With this cooling system, it ranks 86th in the Green500. Compared to its direct predecessor, the VSC-2, it consumes 30 kW more with an output of 450 kW, but achieves more than three times the computing power than its predecessor

VSC-4

VSC-4, with a performance of 2.73 PFlops, was put into operation at TU Wien in July 2019.
