Paris – June 22, 2023 – Eviden, the Atos business for advanced computing, today announced it was awarded a $100M contract with NCMRWF, on behalf of the India Ministry of Earth Sciences, to build two AMD- and NVIDIA-powered supercomputers for weather modelling and climate research for IITM and NCMRWF.

These systems, based on Eviden’s BullSequana XH2000, will have a combined power capacity up to 21.3 petaFLOPS and will rely on Eviden’s patented direct liquid cooling warm water technology.

Located in Noida, India, the NCMRWF supercomputer will have an 8.3-petaFLOPS computing capacity for weather and climate modelling, to support advanced numerical weather research across the country. This platform will bring together 2,100 CPU nodes with AMD EPYC 7643 processors, 18 GPU nodes using NVIDIA A100 Tensor Core GPUs, the NVIDIA Quantum InfiniBand networking platform, and high-performance memory provided by Micron. NCMRWF supercomputer will also have 2PB all flash and 20PB disk-based DDN EXAScaler ES400NVX2 parallel filesystem storage.

The supercomputer dedicated to the Indian Institute of Tropical Meteorology (IITM, Pune) will provide 13 petaFLOPS of power for atmosphere and climate research. It will integrate 3,000 CPU nodes using AMD EPYC 7643 processors and 26 GPU nodes through NVIDIA A100 Tensor Core GPUs. The system will utilize the NVIDIA Quantum InfiniBand networking platform with In-Network Computing, 3PB all flash and 29PB disk based DDN EXAScaler ES400NVX2 storage and Micron high-technology memory.

As part of the contract, the data centers on both sites will also be upgraded.

Dr. M. Ravichandran, Secretary, Ministry of Earth Sciences, said, “Weather and climate research requires massive computing power. This partnership with Atos Group will augment our current capacity to increase resolutions and accuracy of weather forecasts. We look forward to Atos Group in helping us achieve this goal.”

Jean-Philippe Poirault, CEO Big Data and Security, Eviden, Atos Group highlighted, “We are honored to support, through this prestigious contract, IITM and NCMRWF, on behalf of the Ministry of Earth Sciences, in their mission to continuously improve weather modelling and climate research. With a very dynamic growth and a high-quality technological ecosystem, India is a key country for the HPC industry, positioning itself as a frontrunner on the market. The expertise of IITM and NCMRWF combined with the experience of Eviden in delivering the most powerful HPC systems designed for Weather Modelling will provide a unique system ready to tackle the most difficult climate research challenges.”

Eviden designs the scope composed of Atos’ digital, cloud, big data and security business lines.
