The supercomputer 'Perlmutter' equipped with 6159 GPUs 'NVIDIA A100' for data centers is in operation, and the mission is to analyze the mystery 'dark energy' of the universe.

On May 27, 2021, the

National Institute of Energy Science and Technology Computing Center (NERSC) in the United States held a virtual unveiling ceremony for the supercomputer ' Perlmutter ' equipped with 6159 GPUs 'NVIDIA A100 ' for data centers. Perlmutter will run more than 20 applications across disciplines such as astrophysics and climate science.

The newly launched Perlmutter includes 6159 GPUs 'NVIDIA A100' for data centers that first adopted the next-generation architecture ' Ampere ' announced in 2020, and the CPU 'AMD EPYC 7763' (commonly known as AMD EPYC 7763) for servers announced in March 2021. Milan) 'is equipped with about 1500 units and achieves a performance of 60 PFLOPS in high performance computing (HPC) using double precision floating point numbers (FP64). In addition , certain programs such as Quantum Espresso and Berkeley GW can achieve double peak performance. In addition, in the second half of 2021, a CPU node consisting only of 'AMD EPYC 7763' will be added.

Perlmutter bears the name of 2011 Nobel Prize in Physics award-winning astrophysicist

Saul Perlmutter, a hypothesis behind his specialty of ' accelerating expansion of the universe.' It will be used for the analysis of the above existence ' dark energy'. Kitt Peak National Observatory's Dark Energy Spectrometer (DESI) data processing, which can capture as many as 5,000 galaxies with a single exposure, has been reduced from weeks to months to just days. To do. In addition, it will run more than 20 applications across fields such as astrophysics and climate science, and will be used in materials science for complete simulation of atoms in batteries.

So far, NERSC has operated a supercomputer 'Cori ' with a peak performance of about 30 PFLOPS equipped with 2388 'Intel Xeon Haswell' and 9688 'Xeon Phi', but Cori has been operating 'until 2022'. The situation that is said to 'continue'. It is unclear how supercomputers bearing the name of female Nobel laureate Gerty Cori will be treated after 2022.
