In 2004, in the Institute for Informatics and Automation Problems of NAS RA (IIAP) the first high Performance computing cluster (Armenian Cluster - Armcluster) in Armenia had been developed, which consists of 128 Xeon 3.06 GHz (64 nodes) processors. Myrinet high bandwidth and Gigabit networks interconnect the nodes of the cluster. The Myrinet network is used for computation and Gigabit for task distribution and management. The cluster achieved 523.4 GFlops performance by HPL (High Performance Linpack) test. Many intellectual software packages to support the advance in the field of modeling and analysis of quantum systems, signal and image processing, theory of radiation transfer, calculation of time constants for bimolecular chemical reactions, a system of mathematically proved methods, fast algorithms and programs for solving of certain classes of problems in linear algebra, calculus, algebraic reconditibility, test-checkable design of the built-in control circuits have been developed. In addition, user friendly tools and scientific gateways have been developed for Armcluster.
