Optimal transport (OT) has emerged as a fundamental tool in modern machine learning, yet its computational cost remains a significant bottleneck for large-scale applications. While harnessing the massive parallelism of modern GPU hardware is critical for efficiency, the de facto standard Sinkhorn algorithm, despite its ease of parallelization, often suffers from slow convergence in challenging problems. More recently, the sparse-plus-low-rank quasi-Newton method offers a balance between convergence rate and per-iteration complexity; however, its efficiency on GPUs is severely hindered by the serial nature of sparse matrix symbolic analysis and irregular memory access patterns. To bridge this gap, we present cuRegOT, a high-performance GPU solver tailored for entropic-regularized OT. We introduce a suite of algorithmic and architectural optimizations, including an amortized symbolic analysis strategy to mitigate CPU bottlenecks, an asynchronous Sinkhorn iterates generation mechanism, and a fused kernel for bandwidth-efficient gradient evaluation. These strategies are backed by rigorous theoretical guarantees ensuring algorithmic convergence. Extensive numerical experiments demonstrate that cuRegOT achieves significant speedups over state-of-the-art GPU-based solvers across a variety of benchmark tasks.

Has Trump failed to sell the Iran war to the world? Are US-Israeli attacks against Iran legal? As anticipated, it ended up being One Battle After Another's night at the 98th annual Academy Awards, with the political thriller carting away six Oscars out of a total of 13 nominations. But while Paul Thomas Anderson's magnum opus continued its march towards awards-season domination, there were moments of genuine surprise and subversion in Sunday's ceremony. Host Conan O'Brien and his fellow presenters deftly avoided mentioning President Donald Trump by name, but their barbs took direct aim at his policies since returning to office.

The filmmaker behind "One Battle After Another" specializes in stories about people who are cut off, adrift, desperately seeking connection. His films are studies of American loneliness. The director plunges us into the physical realization of experience with a thoroughness that can be unsettling. What is the sound of a needle entering fabric? Something more significant, it seems, than the sound of one hand clapping. You hear a tiny pop followed by the rustle of violated muslin--a shudder in the silence of the universe. Scrupulous directors make sure that the sound of their movies is grossly efficient, so that the dramatic meaning of a scene is apparent even in the worst theatre or home system in the country. They also layer in, for those who care about such things, a secondary level of sound--think of the swishing skirts in Martin Scorsese's adaptation of Edith Wharton's "The Age of Innocence." In " Phantom Thread " (2017)--the needle-and-fabric movie--the director, Paul Thomas Anderson, uses such details to build an exquisitely perceptible epic of minute events.

Windshield wipers' overlooked female inventor On November 10, 1903, Birmingham businesswoman Mary Anderson was issued U.S. Patent No. 743,801 for her "Window-Cleaning Device."

Before cars and buses became ubiquitous features of the modern cityscape, many cities installed streetcars to shuttle residents from neighborhood to neighborhood. In the summer months, the journey was a sweltering one, with dozens of sticky, sweaty passengers crammed together in the heat. The biggest problem wasn't that trolleys were unheated--that advancement came with their electrification in the 1890s--it was that sleet and snow made it impossible for streetcar drivers to see.

Over 11 years, citizen scientists collected billions of data signals for the SETI@home project. Breakthroughs, discoveries, and DIY tips sent six days a week. After reviewing almost 30 years of signals, University of California Berkeley researchers have identified 100 mysterious, deep-space radio blips they want to review for signs of extraterrestrial life . And they couldn't have done it without 11 years of volunteer work from millions of PC owners around the world. Even with today's advanced computers, the world's most complex data problems can't be solved by a single machine.

The evergreen trees give kangaroos, bison, lions, and more extra shelter and fun. Capybaras use donated Christmas trees as wind breaks to protect their habitats. Breakthroughs, discoveries, and DIY tips sent every weekday. The presents are unwrapped, the cookies are crumbs, and that real Christmas tree will become a fire hazard soon enough. Most of us haul it out to the curb for our local sanitation departments to take care of, but some lucky trees make it into the paws of animals living in zoos.

Drone detection technology has led to an increase in airborne smuggling operations over U.S. prisons, putting authorities in a tough spot as federal regulations prevent drones from being brought down.

'Many of these female boobies are really freewheeling it when it comes to sexual behavior.' Breakthroughs, discoveries, and DIY tips sent every weekday. A Galápagos bird species is stunning behaviorists with their "freewheeling" lifestyles.

Players walk clockwise in a circle. When the music stops, everyone sits in a chair. Big Tech is setting in motion its plans for the next gen of lead designers, engineers, AI chiefs, and even CEOs. In Cupertino, Apple execs with familiar faces are retiring or reducing responsibilities. Well, chief operating officer Jeff Williams retired in November, and the speculation is that CEO Tim Cook could follow in the near term. Lisa Jackson, who has led Apple's sustainability efforts since 2013, is now set to retire in January too.

Elon Musk, already the world's richest man, is now on the path to becoming its first trillionaire. Tesla's shareholders recently approved a massive pay package for the CEO, including some $1 trillion in stock options. But the payout will happen only if certain targets are met--including Musk's successful deployment of 1 million Optimus robots. Named after a character, because of course it is, Optimus is a humanoid machine that's supposed to be able to complete boring and dangerous work in place of humans. The robot was unveiled in 2021, when Tesla held an "AI Day" event detailing its future plans.
