Top500 Supercomputers: Who Gets The Most Out Of Peak Performance?

| 13 November 2023 | Timothy Prickett Morgan
The most exciting thing about the Top500 rankings of supercomputers that come out each June and November is not who is on the top of the list. That’s
fun and interesting, of course, but the real thing about the Top500 is the architectural lessons it gives us when we see new systems emerge on the Top500 and we get to see how choices of compute, memory, interconnect, storage, and budget all play out at a system level and across nations and industries.We would normally walk through the top ten machines on the list and then delve into the statistics...

Climate scientists push for access to world's biggest supercomputers to build better Earth models

Nature ^
| July 11, 2023 | by Jeff Tollefson
How quickly will Earth warm, and what will that mean for the planet? To
answer those questions, researchers have spent decades building increasingly sophisticated global-climate models — but those models are straining the limits of available computing power. Now a cadre of scientists is pushing for an ambitious solution: a network of next-generation modelling centres, dubbed Earth Visualization Engines (EVE), where hundreds of staff scientists would use the latest supercomputers to run ultra-high-resolution climate models at full scale. Such models are starting to come online, and many researchers think that they could markedly improve climate projections. Climate simulations model the...

Hackers turn supercomputers into cryptocurrency mining rigs

Hackers have managed to install cryptocurrency mining malware on multiple supercomputers across Europe that have now had to shut down as they investigate...After reviewing malware samples, the UK-based cybersecurity firm Cado Security believes that the attackers likely gained access to the supercomputer clusters by using compromised SSH credentials. These
credentials appear to have been stolen from university staff from Canada, China and Poland who were given access to the supercomputers to run demanding and complex computing jobs.

| 17 June 2019 | Topp500
BERKELEY, Calif.; FRANKFURT, Germany; and KNOXVILLE, Tenn.— The 53rd edition of the TOP500 marks a milestone in the 26-year history of the list. For
the first time, all 500 systems deliver a petaflop or more on the High Performance Linpack (HPL) benchmark, with the entry level to the list now at 1.022 petaflops. Top 10 rundownThe top of the list remains largely unchanged, with only two new entries in the top 10, one of which was an existing system that was upgraded with additional capacity.Two IBM-built supercomputers, Summit and Sierra, installed at the Department of Energy’s Oak Ridge National Laboratory (ORNL)...

| 12 November 2018 | Sean Michael Kerner
The semi-annual Top500 list of the world's most powerful supercomputers was released on Nov. 12, with the U.S holding down the top two spots overall.The IBM POWER9 based Summit system has retained its crown that it first achieved in the June 2018 ranking. Summit
is installed at the U.S. Department of Energy's Oak Ridge National Laboratory and now has performance of 143.5 petaflops per second, up from the 122.3 petaflops the system had when it first came online.The IBM POWER9 Sierra system also improved over the last six months and is now the second most powerful system on the plant...

China's supercomputers race past US to world dominance

| November 13, 2017 | Stephen Shankland
For years, China has claimed the top spot on a list of the 500 fastest supercomputers. Now
it dominates the overall list, too, pushing the United States into second place. For the first time, China has the most systems on the Top500 list, 202, up from 159 six months ago. The US dropped from 169 to 144. And in terms of the total performance of those machines, China also overtook the US, the Top500 supercomputer list organizers said. The news underscores the relentless ascent of China's supercomputing trajectory in recent years. It also marks a notable shift in the international...

The Steve Jobs of supercomputers: We remember Seymour Cray (at 90) Fast, cool, simple. Repeat.

| Oct 2, 2015 | Davin Clarke
Before Steve Jobs, there was Seymour Cray – father of the supercomputer and regarded as something close to a God in the circles he moved in. Jobs’
Apple Computer is reputed to have bought one of Seymour’s massive machines back in the day: a Cray, to design the brand-new Macintosh personal computer. This would have been a significant moment for a man of Jobs' character, not prone to flattering the inventions or ideas of others. In return, Cray is said to have quipped that he'd bought a Mac to design the next Cray. Cray – who would have been 90...

A new climate model, built on the idea that manmade CO2 is not causing runaway warming, proves to be more accurate than massive supercomputing. ___ The current climate models fueling belief in manmade global warming do have fairly good “fit” to the data on which they were tested. However,
the predictivity isn’t that great – see the recent warming “pause” or have a look at the figure above. They’re also hella complex, requiring thousands of hours of supercomputer computations. Early this year, Christopher Monckton of Brenchley, Willie Soon of the Harvard-Smithsonian Center for Astrophysics, David Legates of the University of...

Climate is complex.This is true both in the conventional “wow, this is hard to figure out!” sense, and in the technical sense that people mean when they talk about “complex systems theory.” It’s
so sensitive to the initial assumptions that it’s never feasible to compute exactly how the system will behave. Sometimes this is called “sensitive dependence on initial conditions,” or SDIC.This is basically why we can’t predict if it will rain on Monday, yet we can confidently predict that it’ll be colder in Boulder in December than it was in July.The difference here is between what is exactly true,...

In an effort to give the U.S. a leg up when it comes to supercomputers, the Department of Energy announced its plans to build two GPU-powered supercomputers that will bring the world closer to exascale computing. The
DOE is awarding $325 million to build “Summit” for the Oak Ridge National Laboratory in Tennessee and “Sierra” at the Lawrence Livermore National Laboratory in California while an additional $100 million will go into research for “extreme scale supercomputing” technology. The supercomputers are expected to be installed in 2017 using next-generation IBM POWER servers coupled with NVIDIA Tesla GPU accelerators and NVIDIA...
