Оценка скорости реакции RTOS на события
продолжение темы RTOS, начало см. https://habr.com/ru/posts/1060466/ https://habr.com/p/1062346/ Получив результат, а именно, запуск SMP версии RTOS, задался вопросом, а какая же плата в виде ухудшения временнЫх характеристик взимается за межъядерное взаимодействие сервисов RTOS? Достал из пыльного чулана давно написанный тест производительнсти сервисов RTOS и причесал с целью использования в одно- и много-ядерном режиме.

RTT без JLINK
“Обнаруженный в кустах рояль” под названием IAR i-Jet TRACE позволяет полноценную отладку SMP (Symmetric Multiprocessing) приложения, запущенного на нескольких ядрах многоядерного процессора, в данном случае это Allwinner T113. Полноценная это значит: возможность старт-стоп отдельно каждого ядра, установка breakpoints для каждого ядра, просмотр регистров каждого ядра

Пишем свою OS на Zig: Первый релиз с многоядерностью, FAT32 и скриптами
11 000 строк кода, 95% Zig, 0% стандартной библиотеки: история создания NovumOS с поддержкой SMP, FAT32 LFN и Huge Pages. Привет, Хабр! 👋 Меня зовут Антон, и я хочу поделиться историей создания своей собственной операционной системы. Это моя первая статья и первый серьезный релиз системы ( v0.20 ). Многие разработчики мечтают написать свою операционную систему. Обычно этот путь заканчивается на выводе "Hello World" в VGA-буфер. Я тоже начинал с малого (C# COSMOS), потом уходил в Ассемблер, бросал, возвращался... Но в этот раз я решил пойти до конца. Моей целью было не просто запустить ядро, а создать современную, масштабируемую архитектуру на современном языке. Встречайте NovumOS ...

🐢 Oh, goody—a #tutorial on writing fault-tolerant #multicore programs with #actors, because programming isn't hard enough already! 😂 Just sprinkle some AI fairy dust from GitHub, cross your fingers, and hope your app doesn't combust. 🔥

Настройка ToolChain-a для программирования MCU FlagChip FC7300F8MDT
FC7300F8MDT - это микроконтроллер компании FlagChip as FlagShip . В этом тексте я показал, как можно запрограммировать микроконтроллер FC7300F8MDT, буквально на пустом компьютере.

The #IT industry is staring down #Moore and #Dennard; we are playing chicken with these immovable physical laws. That is reckless, at best.
The "modern miracle" #multicore is but a temporary fix, not a permanent solution. Indeed, most modern programmes are still stubbornly sequential, blithely letting those additional cores sit idle, sip power, and seep heat.
Meanwhile, coders continue to dish out AI-generated JavaScript and Python, with no mechanical sympathy for the von Neumann machine beneath. AI is no panacea; it is but statistics—which dates back to Pascal's days and even earlier—performed by "multicore".
This "if it ain't broke" trend cannot continue, for "it is broke"—now.

Earlier, I wrote a #blog post comparing the standard library sorts in different languages.
I gave an accompanying #talk to the Open Source Connector which is now available online! The talk includes demos of #ChapelLang and #Arkouda and is intended to be accessible to #python programmers. It includes demonstration of #ChapelLang on a #multicore system, showing simple #gpu programming, and running on an #hpc system.
