NERSC supercomputers are used for scientific research by researchers working in diverse areas such as alternative energy, environment, high-energy and nuclear physics, advanced computing, materials science, and chemistry. The Knights Landing processor supports 68 cores per node, each supporting four hardware threads and possessing two 512-bit wide vector processing units. Perlmutter will have a mixture of CPU-only nodes and CPU + GPU nodes. Each CPU + GPU nodes will have 4 GPUs per CPU node. Named “Perlmutter,” in honor of Berkeley Lab’s Nobel Prize winning astrophysicist Saul Perlmutter, it is the first NERSC system specifically designed to meet the needs of large-scale simulations as well as data analysis from experimental and observational facilities.

Oct 30, 2018 Named “Perlmutter,” in honor of Berkeley Lab's Nobel Prize winning astrophysicist Saul Perlmutter, it is the first NERSC system specifically May 5, 2020 Another aspect of the Perlmutter design worth highlighting is that it is NERSC's first supercomputer with an all-flash scratch filesystem (35PB Titan (shutdown this summer). – Summit. ▫ ALCF. – Mira. – Theta. ▫ NERSC DOE – NERSC - Cori.

Perlmutter includes several tools available for profiling CPU and GPU applications. Nsight Systems : low-overhead sampling-based tool for collecting "timelines" of CPU and GPU activity. Nsight Compute : higher-overhead profiling tool which provides a large amount of detail about GPU kernels; works best with short-running kernels. Perlmutter (also known as NERSC-9) is a supercomputer scheduled to be delivered to the National Energy Research Scientific Computing Center of the United States Department of Energy in late 2020 as the successor to Cori.

Named “Perlmutter,” in honor of Berkeley Lab’s Nobel Prize winning astrophysicist Saul Perlmutter, it is the first NERSC system specifically designed to meet the needs of large-scale simulations as well as data analysis from experimental and observational facilities.

1) The Perlmutter GPU partition will have approximately 1500 GPU nodes, each with 4 NVIDIA A100 GPUs and 2) the CPU partition have approximately 3000 CPU nodes, each with 2 AMD Milan CPUs. You can find some general Perlmutter readiness advice here. Perlmutter will be deployed at NERSC in two phases: the first set of 12 cabinets, featuring GPU-accelerated nodes, will arrive in late 2020; the second set, featuring CPU-only nodes, will arrive in mid-2021. A 35-petabyte all-flash Lustre-based file system using HPE’s ClusterStor E1000 hardware will also be deployed in late 2020. NVIDIA A100 GPUs are available in the ThetaGPU extension of ALCF’s Theta and will power NERSC’s next-generation supercomputer, Perlmutter. NERSC supercomputers are used for scientific research by researchers working in diverse areas such as alternative energy, environment, high-energy and nuclear physics, advanced computing, materials science, and chemistry.

The A100 GPUs sport a number of new and novel features we think the scientific community will be able to harness for accelerating discovery. Perlmutter includes several tools available for profiling CPU and GPU applications. Nsight Systems : low-overhead sampling-based tool for collecting "timelines" of CPU and GPU activity.

ExaSystem. Oct 30, 2018 Perlmutter, featuring Nvidia GPUs, will be NERSC's first large-scale GPU system. Earlier in the year, the DOE unveiled Summit and Sierra, two Perlmutter - A 2020 Pre-Exascale. GPU-accelerated System for NERSC.
