Buna seara

Va prezint un program cu ajutorul caruia puteti vedea de cate ori ar merge un program mai repede daca ar folosi simultan mai multe thread-uri, pe PC-ul dumneavoastra. In cazul procesoarelor single core timpii ar trebui sa fie similari, in cazul celor dual-core ar trebui sa mearga de ~ 2x mai repede daca se folosesc 2 thread-uri, iar in cazul celor quad-core de ~ 4x mai repede daca se folosesc 4 thread-uri spre deosebire de unul singur.

Cine face publice rezultatele e rugat sa specifice si tipul de procesor impreuna cu sistemul de operare.

Sincer, ma asteptam la rezultate mai bune la testul multi-threading :P
Apropo, daca nu-s prea indistrect...ce computezi in testele astea? :D

Ma bucur ca va este de folos :)
Sunt curios cum arata rezultatele pe un quad-core.

Si care ar fi explicatia ca folosind 1 thread am timp mai bun decit un core 2 duo, iar folosind 2 threaduri am timp mai prost ?!

Cum se impart aplicatiile (neoptimizate, sa zicem) pe cele 2 core?

La procesoare single core apar timpi putin mai lungi cand se folosesc intens mai multe threaduri, procesorul tot "sarind" de la o chestie la alta.
De ce merge mai repede decat pe un core2duo s-ar putea sa fie legat de tipul de testare.

Din ce am observat, daca ruleaza o aplicatie consumatoare se foloseste doar un core la ~ 100%, celalalt core se ocupa de restul.

Am observat ca la single thread se ocupa in jur de 60-40% cele 2 core-uri... media e permanent 50
la 2 thread sta 100% lipit... ma intreb ce calculezi:P pi cumva? =))

am uitat sa zic ceva: AMD RULLZ !!!! ei au real dual core separat nu doar virtual ca pentium :P (acum probabil au dezvoltat si ei)
