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.

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.

The Berkeley Lab physicist led the team whose work at NERSC contributed to the Nobel prize-winning insight that the universe’s expansion is speeding up. The resulting efforts NERSC and Nvidia are collaborating on software tools for Perlmutter's GPU processors, testing early versions on the existing Cori's Volta GPUs. The "innovative" tools are bullet pointed and NERSC is among the early adopters of the new NVIDIA A100 Tensor Core GPU processor announced by NVIDIA this week. More than 6,000 of the A100 chips will be included in NERSC’s next-generation Perlmutter system, which is based on an HPE Cray Shasta supercomputer that will be deployed at Lawrence Berkeley National Laboratory later this year. Since announcing Perlmutter in October 2018, NERSC has been working to fine-tune science applications for GPU technologies and prepare users for the more than 6,000 next-generation NVIDIA GPU processors that will power Perlmutter alongside the heterogeneous system's AMD CPUs.

We set OMP_NUM_THREADS=68 and -c 272 to give IDL the ability to take advantage of multithreading which is availible in some libraries. Perlmutter System and beyond at NERSC Jack Deslippe NERSC September, 2020. 2 Perlmutter: a System Optimized for Science •NVIDIA A100-accelerated and CPU-only NERSC Hosts GPU Hackathon for Future Perlmutter Users May 21, 2019 Over four days (April 30-May 3), experts from NERSC, Cray, and NVIDIA worked with application code teams to help them gain new understanding of the performance characteristics of their applications and optimize their codes for the GPU processors in Perlmutter. 2020-05-15 · “Across NERSC’s science and algorithmic areas, we have increased performance by up to 5x when comparing a single V100 GPU to a KNL CPU node on our current-generation Cori system, and we expect even greater gains with the A100 on Perlmutter,” said Sudip Dosanjh, NERSC’s director.

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

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.

Today NERSC announced plans for Perlmutter, a pre-exascale system to be installed in 2020. With thousands of NVIDIA Tesla GPUs, the system is expected to deliver three times the computational power currently available on the Cori supercomputer at NERSC. NERSC’s next supercomputer Perlmutter will be an NVIDIA GPU-accelerated Cray supercomputer with AMD EPYC host CPUs and an Ethernet-compatible Slingshot network. Although NERSC users are generally familiar with performance optimization on Intel and AMD CPUs, there are a number of new facets of performance optimization PerlmutterはSummitやSierraと並ぶ米国のPre-Exaスパコンである. その中でNERSCとしてはEdison(NERSC-7)、Cori(NERSC-8)に続いて2020年にPerlmutter(NERSC-9)を稼働させる。 Perlmutter (also known as NERSC-9) will be delivered by American supercomputing company Cray, featuring future generation AMD Epyc CPUs and Nvidia Tesla GPUs, and will be based on Cray's forthcoming supercomputing platform 'Shasta.' NERSC has signed a contract with NVIDIA to enhance GPU compiler capabilities for Berkeley Lab’s next-generation Perlmutter supercomputer.

Perlmutter (supercomputer) - Perlmutter (also known as NERSC-9) is a Energy Research Scientific Computing Center (NERSC) of the U.S. Department of Energy (DOE) has chosen the new architecture for its “Perlmutter” system, Perlmutter, S. Raux, J. Perlmutter, S. Postman, M. We release the results of our simulations as catalogs at http://portal.nersc.gov/project/astro250/glsne/. NERSC Perlmutter.

Perlmutter has been a NERSC user for many years, and part of his Nobel Prize-winning work was carried out on NERSC machines and the system name reflects and highlights NERSC's commitment to advancing scientific research. 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.

The A100 GPUs sport a number of new and novel features we think the scientific community will be able to harness for accelerating discovery. A few of these features include: Unlike multicore architectures like Intel's Knight Landing and Haswell processors on Cori, GPU nodes on Perlmutter have two distinct memory spaces: one for the CPUs, known as the host memory and one for the GPUs called as the device memory. Similar to CPUs, GPU memory spaces have their own hierarchies.

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. 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.
