Inside India's fastest Super Computer

In simple terms, supercomputer is the mother of all computers. It can perform billions or even trillion of operations in a second or even less time. Presently, the supercomputer segment is dominated by U.S.A. Indian space research organization(ISRO) has recently developed a supercomputer named SAGA-220 making it the fastest super computer in India. It is being used by the space scientists to solve complex aerospace problems.



Technical Details


The rating of the supercomputer is based on PETA/Tera FLOPS. Higher the peta flops, faster and efficient is the supercomputer. The SAGA-220 as the name suggests,gives the theoretical peak performance of 220 peta flops(220 trillion floating point operations per second)
ISRO used commercially available hardware and open source software in building this supercomputer.
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).
