The server thread (THREAD_PRIORITY_NORMAL, CPU 0) inherits the priority of the regulator thread (THREAD_PRIORITY_HIGHEST, CPU 1). Thread priority; Priority inheritance; and. As the threads within the server receive requests, they then inherit the priority (but not the scheduling policy) of the sending thread. Suppose there are 3 threads t1, t2 and t3 with priorities 4, 6 and 1. Because there is no activity on TCP from client to server I assume that the only function running on the server Thread is ProcessSystemEvents.
Note that if you were to close the handle to a worker thread before it terminated, this does not terminate the worker thread.
If a thread completes its quantum and there are no other threads at its priority, Windows permits the thread to run for another quantum. Block Memory Pools.
The locking protocols (e.g. By default, if a thread with a higher priority than the mutex owner attempts to lock a mutex, then the effective priority of the current owner is increased to that of the higher-priority blocked thread waiting for the mutex. In computer science, priority inversion is a scenario in scheduling in which a high priority task is indirectly preempted by a lower priority task effectively inverting the relative priorities of the two tasks. Elements that perform system interrupts have a higher priority than user processes. The thread priority aggregation for the home scheduler instance of a thread consists of at least one priority node, which is normally the real priority of the thread.
To create a thread, the Windows API supplies the CreateThread ( ) function.
Improper synchronisation or locking at the kernel can result in random crashes and unexpected results. Kernel synchronisation mechanisms such as semaphore and rt-mutex are also covered.
The calling thread blocks while it is waiting; to continue processing, a calling thread would use WaitForSingleObject and wait for each worker thread to signal its wait object. Priority inheritance in rt-mutex eliminates the priority inversion problem and hence improves real-time performance in the Linux environment.
The real-time operating system (RTOS) also implements priority inheritance. The priority of each thread is determined by the following criteria: The priority class of its process. Predictable synchronization. For more information, see Context Switches. Priority inheritance in rt-mutex eliminates the priority inversion problem and hence improves real-time performance in the Linux environment. Default priority for main thread is always 5, it can be changed later.
To avoid I/O priority inversion (in which a high-I/O-priority thread can be starved by a low-I/O-priority thread), the executive resource (ERESOURCE) locking functionality utilizes several strategies. The bottom line is that every process has a priority rating list, and thread base priority comes from the owning process.
When a lower-priority thread holds a shared resource needed by a higher-priority thread, the RTOS temporarily increases the priority of the thread holding the shared resource so that the resource can return promptly to the higher-priority thread.
This message-driven priority inheritance avoids priority-inversion problems. Some activities such as response to sudden power loss are always executed with higher priority.
Now, suppose both lower and higher priority tasks need to share a common resource (say access to the same file or device) to achieve their respective work. On Windows Vista, threads run by default for 2 clock intervals; on Windows Server systems, by default, a thread runs for 12 clock intervals. The priority level of the thread within the priority class of its process. In the preceding example, when thread 1 is blocked as it waits for thread 3 to complete, Windows CE boosts the priority of thread 3. To resolve the threading issue, Windows CE enables priority inheritance to a depth of one level. Application programs access hardware through the kernel code.
