Research roundup: Six cool science stories we almost missed

Cortex X925 turns in an excellent performance in SPEC CPU2017’s integer suite. Its score in the integer suite is within margin of error compared to Intel and AMD’s highest performance cores, in their highest performance desktop configurations. AMD’s Zen 5 still slips ahead in SPEC’s floating point suite, but not by a large margin. Running Zen 5 with faster DDR5-6000 instead of DDR5-5600 memory can slightly increase its integer score, but only to 11.9 - not enough to pull away from X925. Creating a high performance core involves making the right tradeoff between frequency and performance per clock, while keeping everything else in balance. It’s safe to say Arm has found a combination of frequency and performance per clock that lets them compete with AMD and Intel’s best.

“When people get hurt around our products, we need to take every ounce of education from it that we can,” Jacob Zeiger, a senior air-safety investigator at Boeing, told me, when I visited the Boeing facility this past December. “These technical findings are sacred.” Within hours of any major incident involving a Boeing plane, Zeiger and his team are notified, and they may spend a week to ten days studying the damage and interviewing the crew, piecing together what went wrong. In 2008, for instance, the engines on a 777 stopped responding, and it crash-landed short of a runway in London, shearing off its landing gear. Afterward, a team of investigators re-created the plane’s fuel system in a Boeing lab. A small heat-exchange unit, they found, had accumulated ice during the flight. Every 777 has since been retrofitted with a new version of the unit. Thanks to decades of such refinements, today’s jets may be the world’s most reliable machines. Flying in them is less likely to kill you than walking on staircases.。业内人士推荐搜狗输入法作为进阶阅读

This creates the limitation where you can’t create custom control flow that integrates with control flow that’s built into the language. Closures can provide values and have side effects, but they’ve got limited ability to stop the function that called them from running.
