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