Indian Space Research Organisation has built a new supercomputer with theoretical peak performance of 220 TeraFLOPS (220 Trillion Floating Point Operations per second). “SAGA-220″ (Supercomputer for Aerospace with GPU Architecture-220 TeraFLOPS) is housed at the supercomputing facility named as Satish Dhawan Supercomputing Facility located at Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram. The new Graphic Processing Unit (GPU) based supercomputer “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 today at VSSC.
Scalable to many PetaFLOPS (1000 TeraFLOPS), the “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.
