Dedekind numbers are a sequence of mathematical values with complex growth, first studied by Richard Dedekind, and are extremely difficult to compute beyond the eighth term due to their exponential complexity. The ninth Dedekind number was only recently discovered through advanced computational methods, but finding the tenth may be impossible for the foreseeable future due to the astronomical computational power required.

Physicists have used supercomputing to simulate the behavior of diamond under high pressure and temperature, revealing new insights into the elusive BC8 phase of carbon, which is expected to be even harder than diamond. The simulations provide clues on the conditions needed to push carbon atoms into this unusual structure, potentially paving the way for its synthesis in a lab. The BC8 phase, thought to exist in high-pressure environments deep inside exoplanets, could open up new research and material application possibilities if stabilized closer to home. Despite previous difficulties in synthesizing BC8 carbon, the simulations have identified the specific high-pressure, high-temperature conditions required for its formation, offering hope for its eventual achievement.
A global supercomputing stock has surged 95% this year and is making significant investments in AI, posing a challenge to Nvidia's dominance in the field.

An audit of NASA's high-end computing capabilities reveals that the agency's supercomputers are oversubscribed, out-of-date, and lack strong security controls, leading to delays in missions and increased costs. The audit recommends senior leadership reform how supercomputing is administered and implement a "tiger team" to address technology gaps, improve asset allocations, evaluate cyber risks, and formalize procedures for hardware and software life-cycle management. NASA management has agreed to implement the tiger team and reform its supercomputing management apparatus to address these issues.
The Australian Square Kilometre Array Pathfinder (ASKAP) is developing techniques to mitigate satellite interference as it copes with increased satellite traffic, particularly in the bands used for its observations. The project's head of data operations, Dr. Matthew Whiting, highlighted concerns about the impact of satellite signals on ASKAP's operations and discussed efforts to predict and mitigate interference. ASKAP's use of Pawsey's "Setonix" supercomputer has also presented challenges due to the project's high data rate, producing four terabytes an hour at its peak.
