Kernel Threads

Some articles on kernel threads, kernel, kernel thread, threads, thread:

Light-weight Process - Kernel Threads
... Kernel threads are handled entirely by the kernel ... They need not be associated with a process a kernel can create them whenever it needs to perform a particular task ... Kernel threads cannot execute in user mode ...
Light-weight Process
... Unix System V and Solaris, a LWP runs in user space on top of a single kernel thread and shares its address space and system resources with other LWPs within the same process ... Multiple user level threads, managed by a thread library, can be placed on top of one or many LWPs - allowing multitasking to be done at the user level, which can have some performance benefits ... In some operating systems there is no separate LWP layer between kernel threads and user threads ...
Features New To Windows 7 - Other Features
... This facility is available in both kernel mode, via the KeSetCoalesableTimer API (which would be used in place of KeSetTimerEx), and in user mode with the SetWaitableTimerEx ... Windows operating systems, scheduling of threads inside a process is handled by the kernel ... threading requirements, such as a database server, can benefit from having a thread scheduler in-process ...
Thread (computing) - Processes, Kernel Threads, User Threads, and Fibers - Thread and Fiber Issues - I/O and Scheduling
... User thread or fiber implementations are typically entirely in userspace ... As a result, context switching between user threads or fibers within the same process is extremely efficient because it does not require any interaction with the kernel at all a context switch ... However, the use of blocking system calls in user threads (as opposed to kernel threads) or fibers can be problematic ...

Famous quotes containing the words threads and/or kernel:

    ‘Tis sweet to feel by what fine-spun threads our affections are drawn together.
    Laurence Sterne (1713–1768)

    All true histories contain instruction; though, in some, the treasure may be hard to find, and when found, so trivial in quantity that the dry, shrivelled kernel scarcely compensates for the trouble of cracking the nut.
    Anne Brontë (1820–1849)
