The context retrieved will be the last context remembered by WOW64; this is usually the last user-mode code executed by Thread. After this command is executed, the debugger will have access to the most important registers and the stack trace for this thread. (This behavior is the same as that of .cache forcedecodeuser. Process is called heavy weight process. In computing, a context switch is the process of storing the state of a process or thread, so that it can be restored and resume execution at a later point. This option can only be used if the target is in native machine mode. Context switch is the process of storing and restoring the state (context) of a thread so that execution can be resumed from the same point at a later time. Which thread gets scheduled is dependent upon a lot of factors both inside and outside your code. Context switching is the act of saving the current threads running state so that it can restore a different thread's state so that it can run on the process. (Live debugging only) If this option is included and Thread is nonzero, all transition page table entries (PTEs) for the process owning this thread will be automatically translated into physical addresses before access. This option can only be used if the target is in native machine mode. You can also reduce overhead from thread context switching by making sure you have at least one CPU for each process involved in handling the majority of requests: one CPU for your HTTP server, one for ATG, one for the database server. This sets the register context and enables you to examine the important registers and the call stack for this thread. During a context switch the operating system can do additional work that isn't strictly part of the context switch. ), /r The number of threads my system can run simultaneously at the same time is: Sockets * Core Per Socket * Threads Per Code = 4. The routine Switch (oldThread, nextThread) actually performs a thread switch. OS_Thread_ID: Indicates the Thread ID in Windows Operating System. In other words, extensions such as !thread and !teb will still default to the current thread if no arguments are used with them. When a processor becomes available, the system performs a context switch. The only thing you can do to prevent a particular thread from getting scheduled is to put it to sleep (deprecated as of v2) or block on some object. The async advantage also goes away in our benchmark if the program is pinned to a single core. Thread switching is a type of context switching from one thread to another thread in the same process. ), If the /p option is included and Thread is zero or omitted, this translation will be disabled. (64-bit kernel debugging only) Changes the active context for the thread to the WOW64 32-bit context. Process is isolated. The precise meaning of the phrase “context switch” varies. For more information about the register context and other context settings, see Changing Contexts. Until threads that are suspended or blocked become ready to run, the scheduler does not allocate any processor time to them, regardless of their priority. See Register Context for full details. The thread specified must be running in a process that has a WOW64 state. (This behavior is the same as that of .cache forcedecodeptes.). The .thread command instructs the kernel debugger to use the specified thread as the register context. Update the process control block and other important fields. The dispatcher can call thread switches for various reasons: The kernel dispatcher performs thread scheduling and context switching. Place the thread that just finished executing at the end of the queue for its priority. Remove the thread at the head of the queue, load its context, and execute it. Here is an example. Context switching allows for one CPU to handle numerous processes or threads without the need for additional processors. A thread with a higher priority has become ready to run. If this is omitted or zero, the thread context is reset to the current thread. A context switch takes around 0.2µs between async tasks, versus 1.7µs between kernel threads. But this advantage goes away if the context switch is due to I/O readiness: both converge to 1.7µs. (This behavior is the same as that of .cache noforcedecodeuser. The .thread command specifies which thread will be used for the register context. One common thing is calculating the amount of time the last thread/task/process used so that software (and the end user) can determine where all the CPU time is going.
