SAGA-220 is a supercomputer built by the Indian Space Research Organisation (ISRO). As of May 2011, it is the fastest supercomputer in the nation with a maximum theoretical speed of 220 TFlops.
It was unveiled on May 2, 2011 by Dr K Radhakrishnan, Chairman, ISRO.
The name SAGA-220 stands for Supercomputer for Aerospace with GPU Architecture-220 teraflops.
It is located at the supercomputing facility named Satish Dhawan Supercomputing Facility at Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram.
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 supplied by WIPRO. 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.
The system is being used by scientists to complex aeronautical problems. It has been hinted that it will be used to design future space launch vehicles.
 Top 500 rank
As of 11 May 2012, SAGA-220 was ranked 86th on the Top500 list.
