Introducing NVIDIA Ising, the world’s first open AI models to accelerate the path to useful quantum computers. Researchers and enterprises can now use AI-powered workflows for scalable, high-performance quantum systems with quantum processor calibration capabilities and quantum error-correction decoding.

Ian Buck, VP of Hyperscale and HPC Computing at NVIDIA, sat with @dariogila, Undersecretary for Science at @ENERGY, for a conversation on the future of scientific discovery. As the Undersecretary announced first-round DOE funding to support the Genesis Mission, Ian underscored what it takes to bring that vision to life: advanced computing infrastructure, strong public-private partnership, and close collaboration across national labs, industry, and universities. NVIDIA is excited to be an industry partner of the DOE Genesis Mission.
@tomascooking @tunguz GB200 has full rate FP64 GB300 is 1/64
Oh hey #SC25. We have a surprise for you...
To be chosen to participate in the design of the next iteration is a massive honor for us. Through this project, we target a scientific discovery ecosystem based on full integration of simulation and AI. We hope this will benefit not only Japan, but also researchers worldwide.
Those who have been around #HPC a while know the historical significance (and probably the names) of Japan's flagship supercomputers. They always push the boundaries of technology, but in ways that are driven uniquely by the needs of Japan. blogs.nvidia.com/blog/fugakunex…

@HatemLtaief @HPC_Guru @GeorgHager If you look at DFMA flops (and not GEMM/Tensor Core), the memory bandwidth for NV GPUs has actually grown relative to FLOPs in every generation since Volta. That's the ratio that matters for most simulations.

With this and the physics prize, the Nobel committee recognizes we are in a new era of 'AI for Science'
BREAKING NEWS The Royal Swedish Academy of Sciences has decided to award the 2024 #NobelPrize in Chemistry with one half to David Baker “for computational protein design” and the other half jointly to Demis Hassabis and John M. Jumper “for protein structure prediction.”
