31.3 A CUDA Implementation of the All-Pairs N-Body Algorithm We may think of the all-pairs algorithm as calculating each entryfijin anNxNgrid of all pair-wise forces.[1]Then the total forceFi(or accelerationai) on bodyiis obtained from the sum of all entries in rowi. Each ent...

nbody_screen 这个示例展示了高效的全对全重力 n 体模拟。与 OpenGL nbody 示例不同,没有用户交互。 NV12toBGRandResize 该代码展示了两种使用 CUDA 将 NV12 帧转换并调整大小为 BGR 三平面帧的方法。方法 1,将 NV12 输入转换为 BGR @ 输入分辨率 1,然后调整大小到分辨率 2。方法 2,将 NV12 输入调整大小到...
Based on the research of parallel programming model based on SMP cluster hardware architecture and SMP cluster hierarchy, realization N-body algorithm in the design of hybrid programming model based on OpenMP+MPI+CUDA. Finally, the program test in dawning W580I cluster, and combined with the ...
其中，input代表输入的数组，即一个长度为N的数组，output代表输出数组，即第一阶段的结果，即长度为M的...
这个示例实现了归并排序(也称为 Batcher 排序),属于排序网络类算法。虽然在大序列上一般效率较低,但在对短至中等大小的(键,值)数组对进行排序时,可能是优选算法。参考 H. W. Lang 的优秀教程:http:///lang/algorithmen/sortieren/networks/indexen.htm ...
This example shows how to implement an existing computationally-intensive CPU compression algorithm in parallel on the GPU, and obtain an order of magnitude performance improvement. Supported SM Architecture SM 3.5, SM 3.7, SM 5.0, SM 5.2, SM 5.3, SM 6.0, SM 6.1, SM 6.2, SM 7.0, SM ...
在FlashAttention-3的工作中同样可以看到SASS指令调度的尝试。在其"B.3 3-Stage Pipelining Algorithm"章节中,尝试过将两个WGMMA和softmax部分进行更激进的overlap,但是第二个WGMMA却不能和softmax交叠。考虑到softmax中包含有FADD和FFMA指令,是不是也可以用和DeepGEMM中类似的做法来更好地控制呢?
This allows the user to write the algorithm rather than the interface and code. This section describes how to start programming CUDA in the Wolfram Language.
