Abstract

Sinkronizacijski mehanizmi važni su alati kojima osiguravamo konkurentnost dvaju ili više procesa ili dretvi. Potrebno je osigurati ispravno pristupanje resursima koje navedeni procesi ili dretve dijele istovremeno. Cilj ovog rada jest analizirati podršku sinkronizacijskih mehanizama u jezgri operacijskog sustava Linux. Proučava se osnova sinkronizacijskih mehanizama današnjice, tzv. futex, te implementacija sinkronizacijskog mehanizma mutex. Prikazuju se i napredne funkcionalnosti danog... More mehanizma i predlažu se promjene koje bi trebalo napraviti kako bi se cijela podrška poboljšala. Less

Abstract (english)

Synchronization mechanisms are used in order to ensure concurrency between two processes or between two threads belonging to a single process. Access to resources used by both the aforementioned threads or processes at the same time must be controlled lest race condition occur. The aim of this paper is to analyse the existing implementation of synchronization mechanisms on the Linux operating system. Futex, the kernel system call used as a basis for contemporary synchronization... More mechanisms, is thoroughly examined along with the mutex synchronization mechanism. Advanced mutex use cases are explained and ideas for improvement are put forth. Less
