LLNL’s El Capitan Debuts on Top500 List of Most Powerful Supercomputers

Three new systems currently or soon-to-be sited at Lawrence Livermore
National Laboratory (LLNL) on Monday debuted on the latest Top500 list of
most powerful supercomputers in the world, including the first portion of the
exascale machine El Capitan.
Unveiled at the International Supercomputing Conference in Hamburg,
Germany, the June 2024 Top500 lists three systems with identical components
— one computing rack each from El Capitan’s “Early Delivery System”
(EDS), LLNL’s newest unclassified supercomputer RZAdams and its
unclassified “sister” system Tuolumne. All three registered 19.65
petaFLOPs (nearly 20 quadrillion floating point calculations per second) on
the High Performance Linpack (HPL) benchmark used by the Top500 organization
to determine the world’s fastest supercomputers. The scores ranked them
46th, 47th and 48th in the world, respectively.
LLNL brought the El Capitan EDS cabinet online as part of the overall
installation process of the National Nuclear Security Administration’s
first exascale supercomputer El Capitan, which is projected to exceed 2
double-precision exaFLOPs (2 quintillion operations per second) of peak
performance, making it likely the world’s most powerful supercomputer when
fully deployed.

… STARing into space
Terran Orbital, a global leader in satellite-based solutions primarily
serving the aerospace and defense industries, celebrates the 3rd anniversary
of its successful GEOStare SV2 mission. Launched May 15, 2021, from NASA’s
Kennedy Space Center in Florida, GEOStare SV2 has surpassed expectations,
delivering exceptional results for commercial satellite imagery.
GEOStare SV2 represents a groundbreaking collaboration between Terran Orbital
and Lawrence Livermore National Laboratory (LLNL). The space vehicle
integrates LLNL’s Monolithic Telescope (MonoTele) technology with Terran
Orbital’s expertise producing high-reliability space vehicles. Developed
through a four-year, $6 million cooperative research and development
agreement (CRADA), this mission demonstrates the power of collaboration in
advancing compact satellites for commercial applications.
Beyond capturing more than 60,000 Earth images and 94,000 deep space images,
GEOStare SV2 has served as a valuable testbed for Terran Orbital.

Lawrence Livermore placed in the top 50 best-led companies in Glassdoor’s
inaugural award.
… Leaders are best of the best

Glassdoor, the worldwide leader for workplace conversations and career
insights, has announced the winners of its inaugural award honoring the 50
Best-Led Companies 2024 across the United States and Lawrence Livermore is
one of them. This award honors companies with exceptional senior leadership
teams that go above and beyond to redefine the employee experience. Unlike
other workplace awards, Glassdoor’s awards rely on input over the past year
from employees who anonymously submit a company review on Glassdoor.
This new award comes at a time when a Glassdoor commissioned survey conducted
online by The Harris Poll found that 72% of those employed full/part time in
the U.S. feel confident in their organization’s current leadership team,
and yet, almost half (46%) of U.S. employees hold back their feedback to
management about their experience at work. Shining a light on companies that
excel in transparent and authentic leadership while receiving high praises
from their employees is just one of the many ways that Glassdoor is uniquely
positioned to help job seekers make more informed decisions throughout their
career journey.
When providing a company review, employees are asked to rate several factors
tied to their employment experience. These include rating sentiment around
their CEO’s job performance as well as around senior management, among
other factors.

… Making the impossible possible
https://phys.org/news/2024-05-optimized-high-explosives.html
When materials are subjected to extreme environments, they face the risk of
mixing together. This mixing may result in hydrodynamic instabilities,
yielding undesirable side effects.
Such instabilities present a grand challenge across multiple disciplines,
especially in astrophysics, combustion and shaped charges — a device used
to focus the energy of a detonating explosive, thereby creating a
high-velocity jet that is capable of penetrating deep into metal, concrete or
other target materials.
To address the challenges in controlling these instabilities, researchers at
Lawrence Livermore National Laboratory are coupling computing capabilities
and manufacturing methods to rapidly develop and experimentally validate
modifications to a shaped charge. This work, part of Project Darkstar, is
aimed at controlling material deformation by investigating the scientific
problems of complex hydrodynamics, shockwave physics and energetic materials.
“Like a hurricane, shock waves and the detonation of explosives are
typically deemed ‘uncontrollable’ events. But we have made it our goal to
control these complicated dynamical systems,” said DarkStar’s principal
investigator Jon Belof.
The team employed artificial intelligence (AI) and machine learning (ML) to
explore new, computationally optimized designs. The use of additive
manufacturing — 3D printing — made it possible for researchers to rapidly
realize even the most radical AI-designed components that would otherwise be
considered “impossible” to create using traditional manufacturing
methods.

… Quantum computing goes nuclear https://newsexplorer.net/z/78563.html
The nuclear reactions that power the stars and forge the elements emerge from
the interactions of the quantum mechanical particles, protons and neutrons.
Explaining these processes is one of the most challenging unsolved problems
in computational physics.
As the mass of the colliding nuclei grows, the resources required to model
them outpace even the most powerful conventional computers. Quantum computers
could perform the necessary computations. However, they currently fall short
of the required number of reliable and long-lived quantum bits.
In research published in /Physical Review A/, Lawrence Livermore researchers
and collaborators combined conventional computers and quantum computers to
significantly accelerate the prospects of solving this problem.
The researchers successfully used the hybrid computing scheme to simulate the
scattering of two neutrons. This opens a path to computing nuclear reaction
rates that are difficult or impossible to measure in a laboratory. These
include reaction rates that play a role in astrophysics and national
security.
