Streami: An MPI Data-Parallel Library to Compute Field Lines on GPUs

arXiv:2606.02627v1 Announce Type: new Abstract: We present Streami, an extensible GPU-accelerated library for the computation of field lines in fluid flows on high-performance computers. Streami acts as a thin layer used for both post-hoc or in-situ analysis and can interface with existing MPI applications. We discuss Streami's application programming interface, key design decisions that led to Streami's high performance and extensibility, as well as extensions to support different fluid...

Iterative convergence in phase-field brittle fracture computations: exact line search is all you need

Announce Type: replace Abstract: Variational phase-field models of brittle fracture pose a local constrained minimization problem of a non-convex energy functional. In the discrete setting, the problem is most often solved by alternate minimization, exploiting the separate convexity of the energy with respect to the two unknowns. This approach is theoretically guaranteed to converge, provided each of the individual subproblems is solved successfully.

Storm-Time Cusp Precipitation: Insights from TRACERS Multi-Crossing Observations

arXiv:2605.30620v1 Announce Type: new Abstract: The dayside cusp provides a direct pathway for solar wind plasma entry into the magnetosphere ionosphere system through magnetic reconnection. Using low altitude ion and electron measurements from TRACERS, together with upstream solar wind and geomagnetic conditions, we investigate the evolution of the cusp during a geomagnetic storm on 30 September 2025, spanning its rising, main, and recovery phases, and compare these with a quiet-time...

Ahoy, DECmate II the little PDP-8 that could

Now, that's a lot of word processing. But under the hood it's still at least PDP-8 adjacent, even considering its oddities and incompatibilities, and you can make it do many of the things a full-size Eight can. We'll take this basic unit, convert the floppy drives to solid state, tap the video output, and put it through its paces.

Microsoft's new quantum chip is 1,000 times more reliable than its predecessor — but why is this new chip so controversial?

Microsoft's new quantum chip is 1,000 times more reliable than its predecessor — but why is this new chip so controversial? The Majorana 2 quantum processor is built from topological qubits, and its creators claim it can sustain quantum coherence for an average of 20 seconds — orders of magnitude longer than the milliseconds that conventional chips last. Microsoft has revealed a new quantum computing chip with quantum bits (qubits) it says are capable of maintaining their quantum state for...

Voxel Space

Let us go back to the year 1992. The CPUs were 1000 times slower than today and the acceleration via a GPU was unknown or unaffordable. 3D games were calculated exclusively on the CPU and the rendering engine rendered filled polygons with a single color.

Nanomagnets control diamond qubits, pointing to more scalable quantum hardware

Nanomagnets control diamond qubits, pointing to more scalable quantum hardware Gaby Clark Scientific Editor Robert Egan Associate Editor Quantum computing, once only a theoretical possibility, promises to deliver faster, more energy-efficient computers—but only if scientists can build and scale the hardware needed to run the machines. New research from Virginia Commonwealth University brings scientists one small step closer to quantum computing at a practical scale, which could help...

Building user-driven climate adaptation products

Abstract Climate adaptation products have traditionally been developed using a supply-driven model reliant on available climate information, leading to usability gaps1,2,3,4. To better meet user needs, the climate services field has recognized a need to shift towards a demand-driven model emphasizing co-production, that is, user-driven, scientifically informed products created through shared knowledge practices1,2,3,4,5. However, co-production can be challenging, especially for researchers...
