常用的并行计算方法中,有一种SPMD(Single-Program Multiple-Data)数据并行的方法,简单说就是将数据分片,每片数据经过完整的一个数据处理流程。这个就能和昇腾AI处理器的多核匹配上了,我们将数据分成多份,每份数据的处理运行在一个核上,这样每份数据并行处理完成,整个数据也就处理完了。Ascend C是SPMD(Single-Program...
printf("Address of Parameter: %p\n", ¶m);printf("Pointer is pointing to: %32.30Lf\n", *ptrp); printf("Address of pointer is: %p\n", &(ptrp)); printf("Address of pointer's pointer is: %p\n", &(ptrpp)); printf("Address of pointer's pointer's pointer is: %p\n", &(...
Ascend C是SPMD(Single-Program Multiple-Data)编程,多个AI Core共享相同的指令代码,每个核上的运行实例唯一的区别是就是block_idx(内置变量)不同,这样我们就可以通过block_idx来区分不同的核,只要对Global Memory上的数据地址进行切分偏移,就可以让每个核处理自己对应的那部分数据了。 算子被调用时,所有的计算核心都...

其中,a 是[no%]indirect_array_access。 使用此选项可以确定编译器是否以为直接内存访问生成预取的方式为由选项 -xprefetch_level 指示的循环生成间接预取。 如果不指定 -xprefetch_auto_type 的设置,编译器会将其设置为 -xprefetch_auto_type=no%indirect_array_access。 类似-xalias_level 的选项可以影响计算候选...

The use ofmallocandfree(and related dynamic memory APIs) has many pitfalls as a cause of memory leaks and exceptions. To avoid these kinds of leaks and exception problems, use the pointer and container classes provided by the C++ Standard Library. These includeshared_ptr,unique_ptr, andvector...
