SAGA Supercomputer Uses Tesla GPUs to Assist Indian Space Research

HAMBURG, Germany, Jun 19 -- NVIDIA today announced that the SAGA system, India's most powerful supercomputer(1) and the holder of the 85 position on the Top500 list released yesterday, is leveraging NVIDIA(R) GPUs to dramatically improve the design and analysis of the delivery vehicles critical to the nation's space program.

Developed by the Indian Space Research Organization (ISRO), one of the six largest space research agencies in the world, the SAGA supercomputer is used to tackle complex aeronautical problems. Harnessing the power of 640 NVIDIA Tesla(R) GPUs and providing up to 394 teraflops of peak performance, SAGA enables ISRO to accelerate and improve the design and analysis of new and existing satellite launch vehicles by enabling more complex and accurate design simulations.

"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 program, 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 optimize 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 finalize 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 $1 billion pledge to build a network of next-generation, petascale-class supercomputers throughout the country," said Sumit Gupta, senior director of 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."

About ISRO The Indian Space Research Organization (ISRO) is the primary space agency of the Indian government, and is among the six largest space research organizations in the world. Its primary objective is to advance space technology and use its applications for national benefit, including the development and deployment of communication satellites for television broadcast, telecommunications and meteorological applications, as well as remote sensing satellites for management of natural resources.

About NVIDIA Tesla GPUs NVIDIA Tesla GPUs are massively parallel accelerators based on the NVIDIA CUDA(R) parallel computing platform. Tesla GPUs are designed from the ground up for power-efficient, high performance computing, computational science and supercomputing, delivering dramatically higher application acceleration for a range of scientific and commercial applications than a CPU-only approach.

Exascale Computing: The View from Argonne

As a result of the dissolution of DARPA's UHPC program, the driving force behind exascale research in the US now resides with the Department of Energy, which has embarked upon a program to help develop this technology. To get a lab-centric view of the path to exascale, HPCwire asked a three of the top directors at Argonne National Laboratory -- Rick Stevens, Michael Papka, and Marc Snir -- to provide some context for the challenges and benefits of developing these extreme scale systems.

TOP500 Gets Dressed Up with New Blue Genes

The 39th TOP500 list was released today at the International Supercomputing Conference in Hamburg, Germany, with a new machine at the top. Sequoia, an IBM Blue Gene/Q machine, delivered a world record 16 petaflops on Linpack, knocking RIKEN's 10-petaflop K Computer into second place. The Japanese K machine had held the TOP500 title for a year.
