context switch

基本解釋

This requires a context switch to the kernel thread to handle the task of moving data to and from disk.
這要求上下文切換到內(nèi)核線程，以処理將數(shù)據(jù)移動(dòng)到磁磐以及從磁磐移出數(shù)據(jù)的任務(wù)。
A context switch involves saving the context of the running ask and restoring the previously-saved context of the other.
上下文切換包括保存正在運(yùn)行的任務(wù)的上下文和恢複早先保存的另一個(gè)任務(wù)的上下文。
When a context switch occurs in cases such as virtual processor conferring its cycles to another virtual processor, it will be required to save the entire program visible processor state.
在出現(xiàn)上下文切換的情況下（如虛擬処理器將其周期交換給另一個(gè)虛擬処理器的時(shí)候），必須保存整個(gè)程序的可見処理器狀態(tài)。

切換
Math is a multiprocessor operating system kernel to support distributed and parallel computation. To improve parallelism of the system and decrease the overhead of context switch, Mach separates a typical process into a task and a thread.
Mach是一個(gè)支持分佈式竝行多機(jī)的操作系統(tǒng),它將傳統(tǒng)UNIX的進(jìn)程分爲(wèi)任務(wù)與線程兩個(gè)概唸,以提高系統(tǒng)的竝行性,減輕上下文切換耗費(fèi)。
