Help for Example ; ThreadPool threads ready and waiting for new task

[RahibeMeryem]

Hi,

I have a Eigen matrix around 10milliyon each 1024xfloat32. So I want to create threadPool and evenly distribute the matrix for threds and wait a new job for doing calculation and send back the result which is for a certain conditions complied.

function is :

        auto id = ( feat.row(x)- b_cmp ).squaredNorm();
        if (id < 0.5) {
            std::cout << std::endl << "Buldummm : " << x <<  "    " << distance <<std::endl;
            mutex1.lock();
            found_number.push_back(x);
            mutex1.unlock();

        }

So calculation heavy . feat and b_cmp is Eigen Vectors.

I need to create threadpool for above function each of them has own a pieces of huge data and ready to receive calculation matrix.

I didt find a proper good ThreadPool example.

is there any which is sutable such work ?

I want to

@RahibeMeryem Why do you want to create your own thread pool?
Qt already does it for you: https://doc.qt.io/qt-5/qthreadpool.html
