ISRO has built a supercomputer, which is to be India’s fastest supercomputer in terms of theoretical peak performance of 220 Teraflops (220 Trillion Floating Point Operations per second). The new Graphic Processing Unit (GPU) based supercomputer named “SAGA-220” is being used by space scientists for solving complex aerospace problems. The supercomputer SAGA-220 was inaugurated by Dr K Radhakrishnan, Chairman, ISRO on 23 JUNE’2012.
It was built using commercially available hardware, open source software components and in house developments. The system uses 400 NVIDIA Tesla C2070 GPUs and 400 Intel Quad Core Xeon CPUs . Each NVIDIA Tesla C2070 GPU is capable of delivering 515 gigaflops compared to the Xeon CPU’s more modest contribution of 50 gigaflops. The system cost about INR 140,000,000 to build. The system consumes only about 150 kW.
