Oui, mais bon je répondais à Olivier, qui dit que freeMiNT n'est pasProcess: en gros une application avec son espace mémoire réservé.>Le parallélisme c'est le multi-threading pour Windows.>

"Process" et "threads" sont deux concepts différents, et les deux sont des concepts purement *software*. Et les deux existent aussi bien sous Windows que sous les OS de type Unix. Un process a son espace mémoire propre, inaccessible par les autres process (sauf à mettre en oeuvre explicitement des fonctions de partage de mémoire, par exemple avec mmap() sous Unix), alors que les différents threads lancés depuis un process donné partagent tous le même espace mémoire. Un thread est toujours attaché à un process.

Quand à l'hyperthreading c'est le nom commercial chez Intel de la technologie SMT (Symmetric MultiThreading) et qui consiste à assigner 2 threads (au lieu d'un) sur un seul coeur physique à un instant T pour optimiser le remplissage du pipeline d'instructions. Malgré son nom, cette technologie est indépedante du threading de l'OS, et fonctionnerait tout aussi bien avec un OS qui n'aurait pas de notion de thread.
Si tu comprends ce qui est écrit, peux tu en faire un résumé digeste ?
Thread: un morceau d'application qui s'exécute en parallèle et qui partage l'espace mémoire du process.
Ces deux existent sous Win et Unix.
Hyperthrading: technologie qui assigne deux threads logiques à un seul coeur physique.
Ça te va?
Guillaume.
