ToImmutableArray<TSource>(IEnumerable<TSource>) Creates an immutable array from the specified collection. ToImmutableDictionary<TSource,TKey>(IEnumerable<TSource>, Func<TSource,TKey>, IEqualityComparer<TKey>) Constructs an immutable dictionary based on some transformation of a sequence. ToImmutable...
Because it processes two elements per thread, the maximum array size this code can scan is 1,024 elements on an NVIDIA 8 Series GPU. Scans of larger arrays are discussed in Section 39.2.4.Figure 39-4 An Illustration of the Down-Sweep Phase of the Work-Efficient Parallel Sum Scan ...
// Tasks will be queued in this collection private BlockingCollection<Task> _tasks = new BlockingCollection<Task>(); // Maintain an array of threads. (Feel free to bump up _n.) private readonly int _n = 2; private Thread[] _threads; public TwoThreadTaskScheduler() { _threads = new ...
ToArray<TSource>(ParallelQuery<TSource>) 从ParallelQuery<TSource> 中创建数组。 ToDictionary<TSource,TKey,TElement>(ParallelQuery<TSource>, Func<TSource,TKey>, Func<TSource,TElement>) 根据指定的键选择器和元素选择器函数,从 Dictionary<TKey,TValue> 创建一个 ParallelQuery<TSource>。 ToDicti...
We divide the large array into blocks that each can be scanned by a single thread block, scan the blocks, and write the total sum of each block to another array of block sums. We then scan the block sums, generating an array of block increments that that are added to all elements in...
In turn, once a set of chunks has been processed, partial results can be collected to form the final result. This is the “reduce” phase. An easy example would be a huge array of integers for which you would like to compute the sum (see Figure 1). Given that addition is commutative...
array<int, 5> values = { 1, 2, 3, 4, 5 }; parallel_for(0U, values.size(), [&values] (size_t i) { values[i] *= 2; }); 但這種方法的是過的詳細資訊,需要陣列本身要擷取的 Lambda 運算式,並,視容器 (Container) 的類型,可能會沒有效率。 parallel_for...
In3.4.2 Private Scalars and Private Arrays, different iterations of the outer loop modify the same elements of arrayx, and thus the outer loop cannot be parallelized. However, if each thread executing the outer loop iterations has a private copy of the entire arrayx, then there would be no...
MeanReward=MeanReward+(sum(reward_list)-MeanReward)/i batch_obs = np.array(obs_list) batch_action = np.array(action_list) #通过backup的方式计算G(t),并进行归一化处理 batch_reward = calc_discount_norm_reward(reward_list, GAMMA) #学习 ...
