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.

El sesgo tecnológico actual es absurdo: muchas organizaciones prefieren el gasto recurrente y la dependencia de plataformas de terceros antes que gestionar su propia infraestructura.

Le tienen más miedo a asumir la responsabilidad técnica que al desperdicio financiero. La soberanía digital no solo ahorra recursos, expone la inercia del sector. ⚙️

La «repatriación de la nube» ya es una realidad. Pagar fortunas por servicios en AWS o Azure sin entender el motor debajo ya no es sostenible.

Cada vez más empresas están volviendo al hardware propio y a la administración Bare Metal: menor costo, cero dependencia y soberanía real sobre los datos.

El control volvió a la infraestructura propia. ⚙️

¿Docker o Bare Metal para un servidor de Minecraft? 📦 vs 🖥️

Docker (usando imágenes como itzg/minecraft-server) es ideal para aislamiento y despliegue rápido. Sin embargo, en servidores con cientos de plugins o modpacks pesados, el acceso directo en Bare Metal exprime cada ciclo de CPU al reducir el overhead de E/S.

La arquitectura manda. ⚙️

“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

Stop burning money on raw TFLOPS—Generative AI inference is memory-bound!

While NVIDIA H100 and H200 share identical compute, memory bandwidth changes everything:

• H200 (141GB HBM3e @ 4.8 TB/s) gives 1.9x faster LLM inference
• 1.1 TB node VRAM fits 70B parameter models without sharding
• Zero 84°C thermal throttling using high-density bare metal cooling
• No 10–15% cloud hypervisor tax for maximum token output speeds

🤖💻 Frame: Un nou server grafic X11 pentru Linux scris în întregime în Assembly

Într-o epocă în care industria Linux migrează masiv către Wayland și dezvoltă software complex în limbaje moderne, un proiect incredibil vine să zguduie status quo-ul prin tehnica pură: Frame. Acesta este un server grafic compatibil X11, scris de la zero în întregime în Assembly (ASM).

Proiectul reprezintă un tur de forță ingineresc, demonstrând ce se poate obține atunci când elimini complet straturile intermediare de cod, compilatoarele greoaie și dependințele masive, vorbind direct pe limba procesorului.

Iată caracteristicile uluitoare ale acestui proiect minimalist:

🔹 Performanță brută și latență zero
Deoarece codul este scris direct în Assembly, Frame ocolește toate optimizările (sau limitările) pe care un compilator de C sau C++ le-ar impune.

Latență minimă: Timpul de răspuns între input-ul utilizatorului (mouse/tastatură) și randarea pe ecran este redus la minimul absolut permis de hardware.

Fără supraîncărcare (Zero Overhead): Serverul nu încarcă biblioteci externe gigantice, scăzând drastic numărul de instrucțiuni executate de procesor pentru fiecare cadru (frame) randat.

🔹 Dimensiune microscopică a binarului
Spre deosebire de serverul clasic Xorg, care are nevoie de zeci sau sute de megabiți de biblioteci și dependențe pentru a funcționa, binarul executabil al Frame ocupă doar câțiva kilobiți. Întregul server grafic poate fi stocat pe o veche dischetă, fiind probabil cel mai mic server de afișare funcțional creat vreodată pentru Linux.

🔹 Compatibilitate cu protocolul X11
În ciuda naturii sale experimentale și a limbajului de nivel jos în care este scris, Frame implementează elementele de bază ale protocolului X11. Acest lucru înseamnă că poate, teoretic, să comunice cu clienți X standard, permițând rularea aplicațiilor grafice de bază din ecosistemul Linux direct pe această fundație ultra-ușoară.

🔹 Eficiență extremă a resurselor
Consumul de memorie RAM al serverului se măsoară în câțiva megabiți (sau chiar mai puțin în modul idle), făcându-l o opțiune fascinantă pentru:

Sisteme integrate (Embedded): Dispozitive cu resurse hardware extrem de limitate, unde fiecare octet de RAM contează.

Sisteme de restaurare și recuperare: Medii de boot minimale care au nevoie de o interfață grafică rapidă, fără a încărca RAM-disk-ul.

Frame este un proiect manifest dedicat programării retro-futuriste, o dovadă vie că optimizarea extremă nu a murit și că bătrânul protocol X11 poate fi reinventat în cel mai pur mod cu putință.

Как развивалась виртуализация в Авито

Всем привет! Меня зовут Ярослав Покрепов , я DevOps-инженер в Авито . Виртуализация — это технология создания изолированных и независимых виртуальных сред на базе физических ресурсов. Виртуализация в Авито — это неотъемлемая часть технического стека, как и во многих других IT-компаниях. На этапе основания Авито виртуализация уже была широко распространённой технологией. Проект нуждался в эффективных и гибких решениях для управления ресурсами, в возможности масштабироваться в будущем и в обеспечении стабильной работы при растущей нагрузке. В этой статье попробую провести читателя от истоков виртуализации в Авито до современных решений и показать, как эти изменения повлияли на архитектуру и возможности компании. Описать общую хронологию развития виртуализации без полного погружения в технические детали — об этом расскажу подробнее в следующих частях. Дисклеймер: ранняя история инфраструктуры компании восстановлена не по документации, а по воспоминаниям инженеров, которые работали в тот период. Это устная история — с допущениями, реконструкцией контекста и попыткой передать факты и логику решений.

🔹 Storage: Pure NVMe (SATA is a bottleneck).
🔹 Network: 10Gbps/100Gbps ports for those massive spikes.
🔹 Compute: Intel 14900k or AMD EPYC.
