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...
了解std::vector的方方面面和底层实现 vector是动态扩容的,2的次方往上翻,为了确保数据保存在连续空间,每次扩充,会将原member悉数拷贝到新的内存块; 不要保存vector内对象的指针,扩容会导致其失效 ;可以通过保存其下标index替代。 运行过程中需要动态增删的vector,不宜存放大的对象本身 ,因为扩容会导致所有成员拷贝构...
int a = 0; //全局初始化区 char *p1; //全局未初始化区 int main() { int b; //栈 char s[] = "abc"; //栈 char *p2; //栈 char *p3 = "123456"; //123456在常量区,p3在栈上。 static int c =0; //全局(静态)初始化区 p1 = (char*)malloc(10); //堆 p2 = (char*)malloc...

定义:def groupBy[K](f: (T) ⇒ K): Map[K, Array[T]] 描述:按条件分组,条件由 f 匹配,返回值是 Map 类型,每个 key 对应一个数组 示例:把数组中小于 3 的元素分到一组,其他元素的分到另一组,返回 Map[String, Array[Int]] val a = Array(1, 2, 3, 4) val b = a.groupBy(x => x...
Thunk file, specified as the comma-separated pair consisting of 'thunkfilename' and a character vector. Overrides the defaultthunk filename. Output Arguments collapse all Names of functions found in header files but missing from the library, returned as cell array. ...
An array (vector) is a common-place data type, used to hold and describe a collection of elements. These elements can be fetched at runtime by one or more indices (identifying keys). A distinguishing feature of an array compared to a list is that they allow for constant-time random acce...
