Fibers are instead a form of cooperative multitasking, meaning that a running thread will continue to run until it signals that it can yield to another. It means that it is our responsibility for the fibers to co-operate with each other. This puts us in direct control over when the fibers...
In computer science, a daemon is a process that runs in the background. Python threading has a more specific meaning for daemon. A daemon thread will shut down immediately when the program exits. One way to think about these definitions is to consider the daemon thread a thread that runs ...
An important feature of Monitor.Pulse is that it executes asynchronously, meaning that it doesn't itself block or pause in any way. If another thread is waiting on the pulsed object, it’s unblocked. Otherwise the pulse has no effect and is silently ignored....
task parallelism tends to be unstructured, meaning that parallel work units may start and finish in places scattered across your program. Structured parallelism is simpler and less error-prone and allows you to farm the difficult
In addition to the wait handle and delegate, RegisterWaitForSingleObject accepts a “black box” object that it passes to your delegate method (rather like ParameterizedThreadStart), as well as a timeout in milliseconds (–1 meaning no timeout) and a boolean flag indicating whether the request ...
A hint to a TaskScheduler to schedule a task in as fair a manner as possible, meaning that tasks scheduled sooner will be more likely to be run sooner, and tasks scheduled later will be more likely to be run later. LongRunning 2 Specifies that a task will be a long-running, coarse-gr...
Parallel programming Code that performs intensive calculations can execute faster on multicore or multiprocessor computers if the workload is shared among multiple threads in a “divide-and-conquer” strategy (seePart 5). Speculative execution
Shared memory (using the memory area known in programming as theheap) is a common way to pass information between threads.All threads in an application can access the same address space within the process. Hence, if one thread writes a value on a variable in the shared memory, it can be...
The repented and endIsNigh fields can be cached in CPU registers to improve performance, meaning a delay before their updated values are written back to memory. And when the CPU registers are written back to memory, it's not necessarily in the order they were originally updated....
The .NET compiler is allowed to alter the order of reads and writes in any way which does not change the meaning of the original program. For example, as pointed out in Dr Dobb’s articled (see reference section) it’s legal for the compiler to transform: ...
