In the traditional meaning of the term, as used in 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. This means that user threads are implemented directly on top of kernel threads. In those contexts, the term "light-weight process" typically refers to kernel threads and the term "threads" can refer to user threads. On Linux, user threads are implemented by allowing certain processes to share resources, which sometimes leads to these processes to be called "light weight processes". Similarly, in SunOS version 4 onwards (prior to Solaris) "light weight process" referred to user threads.〔 ==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. LWPs (in systems where they are a separate layer) bind to kernel threads and provide a user-level context. This includes a link to the shared resources of the process to which the LWP belongs. When a LWP is suspended, it needs to store its user-level registers until it resumes, and the underlying kernel thread must also store its own kernel-level registers. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Light-weight process」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
