Chirurgia spinală minim invazivă
Chirurgia spinală minim invazivă oferă pacienților oportunitatea unui tratament eficient, permițându-le o recuperare ultra rapidă și nu în ultimul rând minimizând leziunile induse chirurgical. Echipa noastră utilizează un spectru larg de tehnici minim invazive, din care enumerăm câteva: endoscopia cu variantele ei (transnazală, transtoracică, transmusculară, etc), microscopul operator, abordurile trans tubulare și nu în ultimul rând infiltrațiile la toate nivelurile coloanei vertebrale. www.neurohope.ro |

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. |

Ma bucur ca va este de folos :)
Sunt curios cum arata rezultatele pe un quad-core. Legat de ce face procesorul in timpul testelor, calcule matematice. |

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. Legat de Quote Cum se impart aplicatiile (neoptimizate, sa zicem) pe cele 2 core? |
