The Oak Ridge Leadership Computing Facility hosted Women in Computing's "Introduce Your Daughter to Code" for the second time on June 16, giving daughters of staff members at ORNL a chance to engage in fun programming activities and code on the Cray XK7 Titan supercomputer. This year, 25 girls ages 10 to 18 participated in the labwide event.
OLCF User Support Specialist Suzanne Parete-Koon kicked off the event with an introduction to parallel computing and Titan before ORNL intern Dasha Herrmannova and ORNL postdoctoral research associate Anne Berres walked the girls through the basics of coding in Python.
Katie Schuman, a Liane Russell Distinguished Early Career Fellow, helped the girls use a program called fractalName to generate colored fractals—repeating patterns that form shapes—based on their names and ages. The fractals were displayed on the visualization wall in the Exploratory Visualization Environment for Research in Science and Technology, or EVEREST. The girls also used Schuman's Birthday Pi code to find their birthdays in the first 100,000 digits of the number pi.
"It was really exciting to see the girls' enthusiasm and curiosity when they were coding," Katie says. "Seeing them already thinking creatively about the code is the most rewarding thing to me."
After they coded on the leadership-class machine, the girls explored the interactive Tiny Titan, which features eight Raspberry Pi processors and provides a visual simulation of a liquid in space. Tiny Titan demonstrates how additional nodes in a compute system can increase the speed of a simulation.
Katie says the feedback WiC continues to receive about the event will inform future coding activities. "Some of the parents have already said the girls wanted to download everything and keep playing with the code when they got home," she says. "There is already a desire for the next phase. We will definitely continue running the same curriculum and possibly expand it in the future."
The following staff members contributed to "Introduce Your Daughter to Code:" Berres, Harken, Herrmannova, Parete-Koon, Schuman, Megan Bradley, Kate Carter, Amy Coen, Katherine Engstrom, Megan Fielden, Shang Gao and Ashley Nguyen.

Chip dilemma will buy Beijing precious time
The latest U.S. trade rules effectively make ultra-high-performance microprocessors used in supercomputers off limits to Chinese buyers; as are software and equipment required to make semiconductors above certain technological thresholds, including high-end memory chips from China’s YMTC.
Last year, Chinese imports of integrated circuits and related equipment topped $466 billion.
The outlook for China-dependent players in South Korea, Japan and the Netherlands is more uncertain. Memory giants Samsung Electronics (005930.KS) and SK Hynix (000660.KS) have factories inside the People's Republic and won’t be able to maintain them without a U.S. licence. Both have secured a one-year waiver from the restrictions, but what happens afterwards is unclear.
Washington policymakers are pressuring their Dutch and Japanese counterparts to also ban less sophisticated tools from ASML and Japanese peers. Both governments have agreed in principle to adopt “at least some” of the U.S restrictions, Bloomberg reported on Dec. 12. But the devil is in the details. Dutch Trade Minister Liesje Schreinemacher already said in November her government "will not copy the American measures one-to-one".
Curbs would be painful for the Veldhoven-based company: 2.7 billion euros, or 15% of total revenue, came from the People's Republic in 2021. Rival Nikon (7731.T) made sales of over 153 billion yen ($1.1 billion) in China, some 28% of total.
Slowing demand is another worry: Total chip sales will shrink 4% to $557 billion in 2023, a sharp reversal from the 26% growth in 2021, according to World Semiconductor Trade Statistics.
That will probably make companies wary of quickly and fully embracing Washington's requests. The hesitancy will play in China’s favour. It will buy it time to stockpile on foreign components and tools and help President Xi Jinping court trade partners. As Beijing knows, wars are seldom fought and won unilaterally.

Biden’s China tech crackdown leaves Xi with few ways to hit back
The U.S. has sharpened its assault on China’s technology industry with a flurry of export bans and stifling restrictions on companies, an escalation that leaves Beijing with few options to retaliate.
Washington’s moves are part of a longer-term strategy to prevent China from dominating the industries of the future and arming its military with advanced weaponry, while also securing its tech supply chain by enticing chipmakers to set up shop in the U.S..
President Joe Biden’s administration this week escalated those efforts to hobble its main geopolitical competitor, blacklisting dozens of Chinese tech firms, while signs emerged Japan and the Netherlands are aligning with U.S. restrictions on selling crucial chipmaking equipment to China, a major blow to Beijing’s ambitions to produce advanced semiconductors.
In response, China has accused the U.S. of protectionism, lodged a complaint with the World Trade Organization and courted chip-making powerhouse South Korea, a key U.S. ally. Beijing is also reportedly preparing a multibillion-dollar aid package for its semiconductor industry, a crucial sector for the global economy given the widespread use of chips in everything from cars and mobile phones to guided missiles.
But China doesn’t have many options, or incentives, to go further.
Similar to Beijing’s actions during the trade war with former President Donald Trump’s administration — when it failed to follow through on threats to add U.S. companies to a so-called unreliable entities list — any moves to block American investment threatens an economy already reeling from President Xi Jinping’s zero-tolerance COVID-19 policies, which are only now being rolled back.
"China’s lack of good options is precisely why the U.S. is striking hard and fast now with export controls,” said Reva Goujon, a director at the Rhodium Group who advises corporate clients on U.S.-China relations and industrial policies.
The tech battle comes as U.S.-China relations have eased since hitting a low point earlier this year following a visit to Taiwan by House Speaker Nancy Pelosi. After Biden and Xi met at the Group of 20 summit in Bali last month, the U.S. watered down a legislative proposal that would’ve named Taiwan a "major non-NATO ally,” a sign that Washington is trying to avoid another showdown that risks derailing the relationship.
The U.S. has "abused” export controls and import restrictions, while the new sanctions on Chinese companies "violate the commitment” that Biden made to Xi in Bali, Liu Pengyu, the spokesman for China’s embassy in Washington, said in a Friday briefing.
"From the U.S. side, they are now building walls and barriers, pushing for decoupling and severing supply chains,” Liu told reporters. "We call on the U.S. side to stop disrupting the trade of high-tech products and maintain normal China-U.S. economic and trade exchanges.”
Yet Beijing’s response to the recent U.S. moves on semiconductors has been "very reserved,” according to Henry Wang Huiyao, founder of the Center for China and Globalization, a policy research group in Beijing. The Biden-Xi talks and an upcoming visit to China by U.S. Secretary of State Antony Blinken have laid the groundwork for more understanding and hopefully some relaxation of sanctions, Wang added.
‘Major blow’
The new actions unveiled this week — which follow export controls announced in October aimed at preventing China’s access to machines and know-how to make high-end chips — placed a number of Chinese companies on a so-called entity list, requiring suppliers to get difficult-to-obtain U.S. government licenses.
Among the most notable firms on that list is emerging chip equipment-maker Shanghai Micro Electronics Equipment Group (SMEE), which could stifle Beijing’s efforts to create next-generation semiconductors. The machines that make semiconductors are among the most complicated devices produced by humans and defy reverse engineering, making it difficult for China to develop its own domestic capabilities if it can’t get the equipment elsewhere.
"Having SMEE on the entity list is a major blow for China’s chip sector,” said Martijn Rasser, a former analyst at the Central Intelligence Agency who’s now a senior fellow at the Center for a New American Security think tank.
"It’s the one company that Beijing saw as having potential to produce advanced chipmaking machines, which is essential for China to be a competitive force in the global semiconductor ecosystem,” he said. "Those hopes are now greatly diminished, if not dashed altogether.”
Courting allies
Under the Biden restrictions, China is severely limited in its ability to buy those chipmaking machines from abroad. The critical American gearmakers Applied Materials, Lam Research and KLA can no longer sell their advanced equipment to Chinese customers. But a complete blockade requires cooperation from Japan’s Tokyo Electron and Dutch lithography specialist ASML Holding.
Those U.S. efforts gathered momentum this week with Japan and the Netherlands nearing an agreement to join Washington in tightening controls over the export of up-to-date chipmaking machinery to China. The two governments are considering a ban on the sale of machinery capable of fabricating chips that are at least three generations behind the latest advances available on the market, in line with the rules Washington set out in October.
Also on the blacklist is China’s leading memory chipmaker, Yangtze Memory Technologies, which was once close to a deal to supply Apple, and is a competitor to Samsung Electronics and Micron Technology for mobile phone and personal computer components.
China response
Even if China wins the WTO case, the U.S. can veto any ruling by bringing it to the trade organization’s appellate body, which the Trump administration paralyzed in 2019.
China’s best option may be to pour money into developing its own high-tech chips. Beijing is preparing to unleash a $143 billion aid package for its chip industry, according to Reuters. But it’s not clear how much impact this will have, given the mixed results from the tens of billions that China has already funneled into the sector.
"They can invest more, but the issues right now are not really a lack of resources,” Adam Segal, chair in emerging technologies and national security at the Council on Foreign Relations. "It’s these technological chokepoints they are still vulnerable to.”
There’s a risk that unilateral actions could eventually alienate key U.S. partners, said Jon Bateman, a senior fellow at the Carnegie Endowment for International Peace. As well, Beijing hasn’t yet shown a willingness to leverage its dominance of rare earth minerals or its role as a manufacturing hub because it "has more to lose than to gain,” he said, but that could change.
"China has a lot of capability to retaliate but very limited willingness to do so thus far,” he said. "We may be surprised when that finally happens.”

The subarachnoid space of the optic nerve features trabeculae that bridges the meningeal layers. The function of such structures remains poorly understood and is thought to play a central role in the physiology and pathophysiology of the eye. Synchrotron-radiation micro-computed tomography at PSI, together with the most accurate computational schemes running on the supercomputer at EPFL, hold the promise of shedding light on the mystery concealed by this tract of the white matter.

(Sigh. You never learn, do you, Andy? Have them tilt the circuit board a little so that it isn't completely blown out by the flash.)
I say this completely without sarcasm or a trace of self-consciousness: I think circuit boards from big old computers are legitimately beautiful. Provenance on this one is uncertain. I believe it's a controller board from a CDC 6600. If it is, it's a historically cool item: the 6600 was designed by Seymore Cray himself and is considered to be possibly the world's first supercomputer.
If not, it was definitely the first influential one. Cray set up something like a "skunk works" operation at Control Data and a small team of a few dozen engineers knocked the whole thing out. It was a revolutionary approach to computing and was several times faster than the next most powerful thing on the market.
So. Yes, I came home with this. I held it in my hands lovingly, appraising its form and lines like a work of art.
Very cool sellers, incidentally: they were big wheels at both DEC and the Computer Museum. I think if I hadn't shown up so early -- this was taken a few minutes before the Flea opened -- I would have missed out completely. They had already sold most of their cool stuff by the time I'd come along.
(When someone at the Flea has core memory for sale...that information does not stay private for very long.)
The board is now sitting on my mantlepiece while I ponder a more permanent location and system of hanging. It might just stay where it is.
To get a molecular-level understanding of nanobubble collapse near a solid surface, Priya Vashishta and his colleagues at the University of Southern California used Argonne's supercomputers to simulate and unravel the complex mechanochemistry problem. The goal of this nanobubble collapse simulation, which was run on 163,840 cores, was to improve both the safety and longevity of nuclear reactors.

Retrocomputing (a portmanteau of retro and computing) is the use of early computer hardware and software today. Retrocomputing is usually classed as a hobby and recreation rather than a practical application of technology; enthusiasts often collect rare and valuable hardware and software for sentimental reasons. However some do make use of it.[1] Retrocomputing often gets its start when a computer user realizes that expensive fantasy systems like IBM Mainframes, DEC Superminis, SGI workstations and Cray Supercomputers have become affordable on the used computer market, usually in a relatively short time after the computers' era of use.
en.wikipedia.org/wiki/Retrocomputing
Con il termine retrocomputing si indica una attività di "archeologia informatica" che consiste nel reperire, specialmente a costi minimi, computer di vecchie generazioni, che hanno rappresentato fasi importanti dell'evoluzione tecnologica, ripararli se sono danneggiati, metterli nuovamente in funzione e preservarli.

One of the most iconic designs of all computers has to be the round cray-1 supercomputer with the usefull seating around the computer
Made as a series of virtual experiments, Quantum Fluctuations shows the complexity and transient nature of the most fundamental aspect of reality, the quantum world, which is impossible to observe directly. In the laboratory, elementary particles are observed by measuring the spoils of a proton collision and comparing the findings with data collected from supercomputer simulations. It is perhaps the most indirect method of observation imaginable, a non-representational form of observation mediated by computer simulations.
