context switch การใช้

• These registers also allowed the 8051 to quickly perform a context switch.
• Conceptually, multithreading is equivalent to a context switch at the operating system level.
• This system architecture greatly improves context switches between TSO users or batch regions.
• VBScript that is embedded in an ASP page is contained within context switches.
• This provides a significant performance improvement in thread creation time and context switches.
• A context switch entailed the saving and restoring of only the hard registers.
• This fast context switch is sometimes referred to as a " thread switch ".
• The processor must effectively perform a rapid context switch before executing a different thread.
• The overhead of repeated context switches and underutilization of scheduling quanta degrade overall performance.
• The caller first traps into the kernel, causing a context switch and memory mapping.
• For example, when the operating system's latency and busy-waits by using queuing and context switches.
• With hundreds of threads, a context switch time of 10ms produces a latency in seconds.
• Because of that the context switch in the DioneOS system was optimized for short time.
• Protothreads are also stackless, which means global variables are needed for preserving variables across context switches.
• It seems to be suggesting that a context switch saves registers on " the stack ".
• Using this mechanism a different instruction set could be selected each time a context switch occurred.
• It is expensive to park and unpark a thread, and a slow context switch may occur.
• Context switches require from microseconds to milliseconds, while the Map's own basic operations normally take nanoseconds.
• Having the scrum master also multitasking may result in too many context switches to be productive.
• In the case of GHC Haskell, a context switch occurs at the first allocation after a configurable timeout.
