Nvidia said that supercomputer SAGA system, which holds 86th position on the Top500 list, is leveraging its GPUs. Developed by the Indian Space Research Organisation (ISRO), the SAGA supercomputer is used to tackle complex aeronautical problems.

The SAGA is leveraging 640 Nvidia Tesla GPUs and providing up to 394 teraflops of peak performance.

"GPUs enabled us to reduce the time to create, simulate and verify a new launch vehicle design from weeks to days, while improving the overall quality and durability of the design dramatically," said sources at ISRO. "This level of supercomputing power has made a huge difference in our space programme, by enabling us to continually refine and improve our prediction capabilities."

ISRO leverages the SAGA system and the PARAS-3D application to run compute-intensive, detailed computational fluid dynamics (CFD) simulations that optimise the launch vehicle design for improved performance under a range of flow conditions.

"With GPUs, ISRO is able to run more complex simulations 7-8 times faster than with a CPU-based system, reducing the time to create, test and finalise new designs by the same factor. In addition, the higher compute density in a GPU-based system enables better application scalability while requiring a much lower investment in communication infrastructure."

"The Indian government has jumped into the global supercomputing race in a big way, with its recent Rs.5,464.48 crore ($1 billion) pledge to build a network of next-generation, petascale-class supercomputers throughout the country," said Sumit Gupta, senior director, Nvidia's Tesla business. "India joins the US, China, Germany, Japan, Russia, and other leading nations who are applying supercomputing resources to solve some of the world's most pressing computational, scientific and engineering problems."
