Decommissioned

Matter was decommissioned on June 12th, 2015 and replaced by the Gamma cluster.

Matter

Matter is a Linux-based cluster with 516 compute nodes and a combined peak performance of 37 TFLOPS.

Each compute node (HP SL170z) is equipped with two quad-core processors of type Intel® Xeon® E5520 and 36 GB RAM. There are also four "fat" nodes with two Intel® Xeon® X5570 CPUs and 144 GB RAM.

Computing services provided by Matter

  • Running traditional HPC batch jobs, submitted from the login node ("head node")
  • Interactive use of compute nodes (for e.g test, development or to run graphical applications)

Research performed with Matter

Kappa is open for users within Linköping University.

History

  • 2010 - Matter was installed (funded by the MATTER consortium)
  • November 1, 2014 - MATTER consortium funding for Matter ended
  • November 2, 2014 - Matter continues in operation as a LiU-funded system
  • June 12th, 2015 - Matter retired

Who can use Matter?

Access to Kappa is granted by NSC. Local researchers at Linköping university can apply for computing time on Kappa. See applying for a new project for details.
