30th Annual Report 2017-18

156 Staff of the Computing Facility at IUCAA Datacentre. The High Performance Computing clusters are seen in the background. High Performance Computing The High Performance Computing facility houses some of the major IT assets of IUCAA. The services for general users are provided through the 1504 core 30Teraflop HPC system “Perseus”, which also has a 750Terabyte storage attached to it. The cluster was available for general use with Load Sharing Facility (LSF) as the job scheduler. The Perseus cluster was utilized by more than 35 high volume users from IUCAA and various Indian Universities, running applications for Molecular Scattering, Molecular Dynamics, Stellar Dynamics, Gravitational N-body Simulations, Cosmic Microwave Backgound Evolution, Fluid Mechanics, Magnetohydrodynamics, Plasma Physics and the analysis of diverse astronomical data. One major data analysis application has been to compute 35 statistical parameters from each of the 500 million optical light curves of astronomical sources observed in the Catalina Real-time Transient Survey (CRTS), by going through the entire repository collected over the years.
