SIMD – neboli Single Instruction, Multiple Data – znamená, že procesor může jednou instrukcí zpracovat více datových prvků najednou. Typicky to znamená, že místo sčítání dvou čísel přičtete dvě sady čísel paralelně. To může přinést výrazné zrychlení například při zpracování obrazu, audia nebo numerických výpočtů.

Pokud již SIMD znáte, tato tabulka je vše, co budete potřebovat. A pokud s SIMD teprve začínáte, tabulku pochopíte do konce tohoto článku

#KaiXian #KX7000 is #Zhaoxin’s latest #CPU, featuring a #x86_64 architecture. The core dubbed #CenturyAvenue is 4wide, #AVX2 capable with an out-of-order execution window on par with Intel CPUs from 2010.
Single-threaded performance is close to AMD’s Bulldozer #FX8150 which leads by 13.6% there. In Multithreaded Performance the KX-7000 is soundly beaten even by Bulldozer.
Zhaoxin is part of #China’s effort to build domestic chips in case western ones become unavailable.

Update for Windows PCs with ARM chips could improve compatibility with x86 games and applications

Qualcomm’s Snapdragon X processors are the fastest ARM-based chips available for Windows laptops to date, making PCs with ARM chips competitive with their Intel and AMD-powered counterparts for the first time.

But hardware is only part of the puzzle. Most PC applications are designed for systems with x86 processors. So Microsoft developed an emulator called Prism that allows you to run x86 […]

AVX2 tip! `PANDN(x, PCMPEQB(y, 0))` where the MSB of `y` is always unset can be transformed into `PSIGN(y, x)`. If you want to mask some elements `x` based on whether an input `y` is non-zero, and the MSB of `y` is always unset, you can multiply `x` by the sign of `y` (which will be 0 or 1) in 1 cycle using `PSIGN`. I think this is actually a pretty common pattern, but compilers can't really see it because of the MSB check.

Hmpf. #AbletonLive 12 braucht mindestens eine CPU der 5. Generation mit #AVX2-Befehlssatz.

Как оптимизировать код на С для x86-процессоров: подсистема кэша и памяти, инструкции AVX-512

Меня зовут Андрей Бакшаев, я ведущий инженер-программист в YADRO. Моя команда занимается разработкой и оптимизацией математических библиотек под архитектуру x86. До этого я 15 лет работал в Intel. Значительная часть моих задач заключалась в том, чтобы реализовывать некоторые алгоритмы обработки изображений и сигналов в довольно известной математической библиотеке IPP, максимально эффективно используя возможности процессоров. Я также исследовал производительность этих алгоритмов в процессорах на ранней стадии проектирования. В статье я поделюсь своим опытом оптимизации низкоуровневого кода на языке C. Рассмотрим подсистему кэша и памяти процессоров и новые инструкции AVX-512. Разберем пример ускорения копирования байтового массива данных и посмотрим, как векторизованный код позволяет сократить время работы широко используемого алгоритма замены байтов по таблице с 619 до 34 мс, то есть примерно в 18 раз.

Some of y'all to let those Ivy bridge and Sandy bridge systems retire. So close to ubiquitous support for #AVX2, but not quite high enough to make it the de facto minimum across programs.

What do people use to analyze #SIMD code these days? I've got some #AVX2 code targeting Zen2 that I want to profile or statically analyze. AMD's uProf only samples at 1ms intervals, and I don't think microbenching is going to be much help.
