parallel_do和parallel_for_each:将算法应用于一个区间 vector<size_t>v; parallel_do(v.begin(), v.end(), [](size_t i){cout<< i <<endl; }); parallel_for_each(v.begin(), v.end(), [](size_t i){cout<< i << endl; }); parallel_reduce 类似于map_reduce,但是有区别。它先将区...
Catégorie GUID qui décrit des événements ETW déclenchés par le runtime d'accès concurrentiel directement en rapport avec l'utilisation de la fonctionparallel_for_each. const __declspec(selectany) GUID PPLParallelForeachEventGuid = { 0x5cb7d785, 0x9d66, 0x465d, { 0xba, 0xe1, 0x46...
下列範例使用 run_with_cancellation_token 函式來呼叫 parallel_for 演算法。 run_with_cancellation_token 函式採用取消語彙基元作為引數,並以同步方式呼叫所提供的工作函式。 由於平行演算法是建置在工作上,所以其會繼承父工作的取消語彙基元。 因此,parallel_for 可以回應取消。
有关演示此概念可以使用 concurrency::run_with_cancellation_token 函数运行调用 parallel_for的示例,请稍后参见 取消并行算法 文档。[Top]取消标记和任务复合concurrency::when_all 和concurrency::when_any 函数,这些函数有助于您撰写多个任务以实现常见模式。 本节描述这些函数如何与取消标记一起使用。当提供一个...
Le prestazioni di parallel_for_each dipendono dall'operazione che richiede più tempo. Pertanto, non c'era da aspettarsi un miglioramento lineare delle prestazioni tra la versione seriale e quella parallela di questo esempio.Argomenti correlatiEspandi la tabella ...
A category GUID describing ETW events fired by the Concurrency Runtime that are directly related to usage of theparallel_for_eachfunction. const __declspec(selectany) GUID PPLParallelForeachEventGuid = { 0x5cb7d785, 0x9d66, 0x465d, { 0xba, 0xe1, 0x46, 0x11, 0x6, 0x1b, 0x54, 0x...
Becauseparallel_for_eachacts concurrently, the parallel version of this example must sort theconcurrent_vectorobject to produce the same results as the serial version. Note that the example uses a naïve method to compute the Fibonacci numbers; however, this method illustrates how the Concurrency ...

(c) reformat a symbol length into a number representing a particular number of bits in a symbol, (d) generate a packed form of output data, (e) provide noise suppression, (f) provide scratch detection and/or (g) set minimum symbol length or number of bits for a valid symbol; (vi) ...
Then, the phoneme labeling for each group is carried out in parallel. An unspecified speaker is assumed to be suitable to one of the parallel branches. Through experiments, the PPL method showed a better performance than the usual method with only a single universal reference pattern set.Imai...
