ISRO builds India's fastest Supercomputer SAGA-220

Indian Space Research Organisation 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 supercomputer is named SAGA 220 which consist of the Graphic Processing Unit (GPU). SAGA 220 stands for Supercomputer for Aerospace with GPU Architecture-220 TeraFLOPS.

The computer is being used by space scientists for solving complex aerospace problems.



"SAGA-220" Supercomputer is fully designed and built by Vikram Sarabhai Space Centre using commercially available hardware, open source software components and in house developments. The system uses 400 NVIDIA Tesla 2070 GPUs and 400 Intel Quad Core Xeon CPUs supplied by WIPRO with a high speed interconnect. With each GPU and CPU providing a performance of 500 GigaFLOPS and 50 GigaFLOPS respectively, the theoretical peak performance of the system amounts to 220 TeraFLOPS. The present GPU system offers significant advantage over the conventional CPU based system in terms of cost, power and space requirements. The total cost of this Supercomputer is about Rs. 14 crores. The system is environmentally green and consumes a power of only 150 kW. This system can also be easily scaled to many PetaFLOPS (1000 TeraFLOPS).
