Management information doesn't change between threads, only the stackĪnd register set do, which means less data to copy on context switches. Stall in any single thread won't keep the others from doing theirįor the operating system, switching between threads is normally cheaper Thread to process user input, and a thread to play the actual media. Incoming media, possibly from a harddrive, CD, Important when many threads are doing blocking I/O operations.Ī media player, for example, can have a thread for pre-buffering the Operates independently of all the others. Secondly, and often more importantly, it allows the programmer toĭivide each particular job of a program up into its own piece that Multithreading will be one of the simplest ways to boost performance. Processors and Intel Pentium 4's with HyperThreading, Processors become commonplace, such as Dual-Core Single-CPU system, but without the added speed. A multithreaded application works just as well on a Well, for starters, multiple threads can run on multiple CPUs, providing a performance This makes communicationīetween threads fairly simple, but there are a few caveats that will be Memory space, so all their memory is shared. Own individual program, except that all the threads work in the same When a program is split into many threads, each thread acts like its Not be immediately obvious why this is useful, but there are Split into many "threads" that all execute concurrently. Multithreading - An OverviewIn most modern operating systems it is possible for an application to
