Design Space Exploration of DMA based Finer-Grain Compute Communication Overlap
arXiv:2512.10236v2 Announce Type: replace Abstract: Modern ML workloads demand distributing training and inference across multiple GPUs. However, these parallelization techniques often suffer from exposed critical-path communication, leaving a potential 1.7x speedup on the table through compute-communication overlap. Prior overlapping methods harness the fact that ML model state and inputs are already sharded into the number of GPUs, and overlap the compute and communication at shard...

WSL 2 is getting faster Windows file system access
WSL 2 is getting faster Windows file system access From DrvFs in WSL 1 to Plan 9 to virtiofs, cross-OS file access in WSL 2 has improved with each generation. A new change gives each virtio device its own dedicated DMA pool, removing the last major contention point on the virtiofs path. If your workflow crosses the Windows/Linux boundary, file I/O performance in WSL 2 has been getting steadily better.
Emerging Amines reshape the paradigm of urban atmospheric particle formation
Announce Type: replace Abstract: New particle formation (NPF) contributes to more than half of global aerosol number concentrations, with profound implications for human health and climate change. Observational studies have shown that the frequency of NPF events in urban Beijing during summer exceeds the global average. The prevailing paradigm attributes urban NPF primarily to sulfuric acid-base nucleation involving dimethylamine (DMA).

No tech rule exemption for Apple, EU regulators say amid spat over Siri AI delay
No tech rule exemption for Apple, EU regulators say amid spat over Siri AI delay BRUSSELS, June 9 : EU regulators on Tuesday slammed Apple for blaming EU tech rules for its decision not to roll out its upgraded assistant Siri AI in the European Union for now, saying they had rejected the company's request for an 18-month exemption from its obligations. The iPhone maker on Tuesday said Siri AI would not be available initially in the EU on iPhones or iPads and faulted the European Commission...
EU court partially sides with Meta in a blow to the European Commission
The EU's General Court has annulled Facebook Marketplace's gatekeeper designation under the Digital Markets Act — but the ruling is largely procedural, as the Commission had already stripped the platform of that status a year earlier. The General Court of the European Union annulled the European Commission's "gatekeeper" designation for Facebook Marketplace, finding that the EU executive failed to adequately justify the designation. The court's ruling, issued on Wednesday in Luxembourg,...
Apple tells everyone 'loud and clear': We are deeply disappointed by Europe
Apple has announced that its “Siri AI” upgrade will be indefinitely delayed on iPhones and iPads within the European Union. The tech giant unveiled the entirely reimagined, Apple Intelligence-powered assistant at its annual conference, WWDC 2026. The company said that regulatory gridlock means users in Europe will be left out when Siri AI on iOS 27 and iPadOS 27 launch later this year.
Apple blames EU rules as it withholds new Siri AI from European devices
BRUSSELS — Apple has said it would not ship its overhauled AI assistant on its devices in the EU, pinning the holdout squarely on Europe’s Big Tech market dominance rules. The iPhone maker on Monday announced its redesigned AI-enabled assistant, branded Siri AI, at its developer conference in Cupertino, California. Shortly afterwards, Apple confirmed that EU users will not get Siri AI on iPhones and iPads when its latest update ships this fall, with no timeline for when or whether that...
Meta loses challenge against EU gatekeeper label for Messenger
Meta loses challenge against EU gatekeeper label for Messenger BRUSSELS, June 3 : Meta Platforms lost its fight on Wednesday against the EU's labelling of its Messenger app as a powerful 'gatekeeper', which places obligations on tech companies with significant influence. Europe's second-highest court upheld the European Commission's finding that Messenger is an important gateway for businesses to reach users, triggering obligations under the bloc's Digital Markets Act. "The Commission did...
