Блин, надо же было такую путаницу устроить..

Потому что sse3 называется pni - Prescott New Instructions.

Всё-таки, почему в cpuinfo нету SSE3?

У меня там контейнер был.

Понятно. Короче я наделал функций с simd-инструкциями для вращения векторов, а вышло, что они работают медленнее, чем куча не-simd инструкций. При том, что на слабых телефоне и нетбуке ситуация с точностью наоборот. Подумал, может интеловские атомы, которые там стоят такие крутые, но я смотрю, у вас всё то же самое. Значит, я криворукий

Таки попробовал на нетпуке скомпилировать, говорит такое:

Re:Нужна помощь тестеров.

Sat, 19 Mar 2016 09:15:26 +0300

А как узнать поддерживается ли оно у меня? Согласно ВиКи, АМД Феном-2 и Штеуд Атом его должны поддерживать, но я хоть убей не вижу SSE3 в /proc/cpuinfo - есть всё что хошь: sse2, ssse3, sse4a но только не sse3.

Нужна помощь тестеров.

Sat, 19 Mar 2016 03:42:24 +0300

У кого процессоры Intel (любые, лишь бы sse3 поддерживали), можете помочь, запустив пару бенчмарков из моей библиотеки воксельной графики?

Зависимости там SDL1.2 и iniparser (во фряхе есть для последнего порт). Делать нужно так:

text

git clone git://github.com/shamazmazum/voxvision.git

cd voxvision

mkdir build

mkdir build-sse

cd build

cmake -DCMAKE_BUILD_TYPE=RELEASE ..

make

make run-benchmarks-voxrnd

cd ../build-sse

cmake -DCMAKE_BUILD_TYPE=RELEASE -DSSE_INTRIN=ON ..

make

make run-benchmarks-voxrnd

Нужно предоставить вывод make run-benchmarks-voxrnd из двух конфигураций. Там ещё можно поиграться с рендерером, но если у вас не фряха с GCD, то будет адово тормозить.
