I have a function that I need to run twice with different data parameters. This function takes long time to run and does heavy computational job.

How I can do that, with which TBB mechanism? Or not even TBB, if I can do this with STL, please give me an example.

UPD:

For example I have a function that takes as a parameter image and does some processing to it:

int Compute(cv::Mat I) { /* computations */ return 0; } void callf(cv::Mat I1, cv::Mat I2) { // make call of this functions parallel Compute(I1); Compute(I2); }

  • Do you mean templates? Without knowing what exactly you are trying to do, it would be difficult to suggest any STL data structure. Commented May 12, 2016 at 10:25
  • So you mean threading? Maybe have a look at std::thread Commented May 12, 2016 at 11:30

You can use tbb::task_group or tbb::parallel_invoke in conjunction with lambda functions like here:

void callf(cv::Mat I1, cv::Mat I2) { // make call of this functions parallel tbb::parallel_invoke( [&]{ Compute(I1); }, [&]{ Compute(I2); } ); }
