比如 [5 ✖️ i32] %0 可以理解为 vector<int> %0(5)。Vectors类型和Arrays类型类似 Label 类型用来表示基本块。C语言中“函数“是最小课调用的单元,通过函数名调用;LLVM IR中最小课调用单元是基本块,所以需要一个类型来表明基本块,也需要一个名称来调用基本块,这种类型就是Label。 其他类型,比如浮点数...

Ascend C分别针对Vector、Cube编程设计了不同的流水任务。开发者只需要完成基本任务的代码实现即可,底层的指令同步和并行调度由Ascend C框架实现,开发者无需关注。 2.2 矢量编程范式 矢量编程范式把算子的实现流程分为3个基本任务:CopyIn,Compute,CopyOut。CopyIn负责搬入操作,Compute负责矢量计算操作,CopyOut负责搬出操作...
使用std::vector或者std::array来替代传统的数组 其它适合使用场景的对象 智能指针 自C++11开始,STL中引入了智能指针(smart pointer)来动态管理资源,针对使用场景的不同,提供了以下三种智能指针。 unique_ptr unique_ptr是限制最严格的一种智能指针,用来替代之前的auto_ptr,独享被管理对象指针所有权。当unique_ptr对象...
Mapping chromatin loops from noisy Hi-C heatmaps remains a major challenge. Here we present DeepLoop, which performs rigorous bias correction followed by deep-learning-based signal enhancement for robust chromatin interaction mapping from low-depth Hi-C
int sum_integers(const std::vector<int> integers) { auto sum = 0; for (auto i : integers) { sum += i; } return sum; } 对于这个例子,无论这是否是最优雅的向量求和实现方式都无关紧要。接口被导出到我们的示例库中的sum_integers.hpp,如下所示: ...
In3.4.4 Reduction Variables, the loop computes the vector product of two arrays into a common variable calledsum. This loop cannot be parallelized in a simple manner. The compiler can take advantage of the associative nature of the computation in statement S1 and allocate a private variable call...
