          • Definition(s)
            • Multithreading typically refers to sharing a single CPU between multiple tasks (or "threads") in a way designed to minimise the time required to switch threads. This is accomplished by sharing as much as possible of the program execution environment between the different threads so that very little state needs to be saved and restored when changing thread. Multiple threads can be executed in parallel on many computer systems. This multithreading generally occurs by time slicing, wherein a single processor switches between different threads--in which case the processing is not literally "simultaneous", for the single processor is only really doing one thing at a time. On a multiprocessor system, threading can be achieved via multiprocessing, wherein different threads can run simultaneously on different processors. www.NetworkDictionary.com
          • Example sentence(s)
            • The design of the Java language makes multithreading essential for all but the simplest applets. In particular, IO and GUI programming both require multithreading to provide a seamless experience for the user. - IBM by
            • On a multi-processor computer, multithreading is implemented with a mixture of time-slicing and genuine concurrency – where different threads run code simultaneously on different CPUs. - O'Reilly Media by
            • Multithreading requires careful programming. For most tasks, you can reduce complexity by queuing requests for execution by thread pool threads. - Microsoft Corporation by

          • Additional fields of expertise
          • Definition(s)
            • Wielowątkowość (ang. multithreading) – cecha systemu operacyjnego, dzięki której w ramach jednego procesu może wykonywać kilka wątków lub jednostek wykonawczych. Nowe wątki to kolejne ciągi instrukcji wykonywane oddzielnie. Wszystkie wątki tego samego procesu współdzielą kod programu i dane. Wikipedia - by Michał Kaczyński
          • Example sentence(s)
            • Wielowątkowość może być więc zdefiniowana następująco: jeśli ze względu na opóźnienia w komunikacji między procesorem a pamięcią, pojedyncze zadanie nie będzie w stanie całkowicie wykorzystać zasobów procesora, jednoczesne przetworzenie wielu zadań trwałoby krócej niż wykonanie ich sekwencyjne. Innymi słowy, wielowątkowość oznacza możliwość uruchomienia więcej niż jednego ciągu instrukcji (wątku) w tym samym czasie. W tym celu procesor powinien mieć więcej niż jeden licznik i zbiór programowalnych rejestrów. Powielenie tych zasobów jest dużo mniej kosztowne niż wymiana całej jednostki obliczeniowej. - Elektronika2b by Michał Kaczyński

            • višenitnost
          • Additional fields of expertise
          • Definition(s)
            • Višenitnost omogućava programeru da unutar svog programa pokrene više niti izvršavanja i time ubrza rad programa. Primjerice, jedna nit može u pozadini obavljati složena preračunavanja, dok druga već prikuplja nove podatke od korisnika. Višenitno izvršavanje programa donosi i veću učinkovitost procesora, jer jedna nit može koristiti njegove resurse u trenucima dok je druga nit besposlena. FER, Zagreb - by Ivan Nekic
          • Example sentence(s)
            • Višenitnost (višedretvenost, eng. multithreading): Višenitni program sastoji se od 2 ili više dijelova koji se mogu istovremeno izvršavati (pseudo-paralelizam). Svaki dio takvog programa naziva se nit ili dretva (eng. thread). Ime dolazi od ‘thread of execution’. Svaki proces ima barem jednu nit. Primjer: tekst procesor, web server, matrični kalkulator... Prednost: Bolja iskoristivost procesorskog vremena, posebno kod programa koji imaju sporiji I/O. - Auditorne, FER, Zagreb by Ivan Nekic
            • Podržava li Linux višenitnost ili lakše procese? Uz Unixov model višezadaćnosti koji uključuje teže procese, što je naravno dio standardnog kernela Linuxa, ima nekoliko implementacija lakših procesa ili niti. Noviji kerneli koriste model niti kthreads. - Linux često postavljana pitanja (FAQ) by Ivan Nekic
            • Java programi mogu se izvoditi na svakoj arhitekturi na kojoj je implementiran Java virtualni stroj. Implementacija je relativno jednostavna ukoliko ciljna platforma zadovoljava neke osnovne preduvjete, kao što je npr. podrška za višenitni rad (multithreading). [...] U Java platformi višenitnost je sadržana u definiciji jezika, dok se u jeziku C / C++ višeprocesni rad i višenitnost ostvaruju preko sistemskih poziva operacijskog sustava (npr. UNIX fork – exec mehanizam). Java također uključuje definicije sinkronizacijskih primitiva. Nadalje, sistemske biblioteke napisane su tako da budu “thread safe”, tj. omogućuju paralelno izvođenje funkcija (metoda!) u različitim nitima. - Programski jezici, ETF, Osijek by Ivan Nekic
