这里先放一段代码,它并发地执行一个有内存申请和释放操作的函数: #include <iostream>#include <tbb/parallel_for.h>#include <tbb/tick_count.h>#include <vector>usingnamespacetbb;voidalloctask(int) {//vector构造和析构时会申请和释放空间std::vector<int> data(100); }intmain() { tick_count t1 ...
tbb::task_scheduler_init init_parallel; if(!run_pipeline (0)) return 1; } } return 0; } 第二个程序,对应debug模式,带上tbb_debug.lib: #include "tbb/task_scheduler_init.h" #include "tbb/blocked_range.h" #include "tbb/parallel_for.h" ...

Solved: Usually we use tbb::parallel_for and std::for_each for the same goal. It is to applay some actions to all array elements. But what will
