How can I solve this problem?

[Darius_Nicholas]

This is my code !

#include <vector>

#include <iostream>

#include <CL/sycl.hpp>  // DPC++ header

std::vector<std::vector<double>> filter2d(const std::vector<double>& b, double a, const std::vector<std::vector<double>>& x) {

    int rows = x.size();

    int cols = x[0].size();

    std::vector<std::vector<double>> y(x.size(), std::vector<double>(x[0].size()));

    sycl::queue q(sycl::gpu_selector{});

    sycl::buffer b_buffer(b);

    sycl::buffer y_buffer(x);

    sycl::buffer x_buffer(y);

    q.submit([&](sycl::handler& h) {

        sycl::accessor x_acc(x_buffer,h,sycl::read_only);

        sycl::accessor b_acc(b_buffer,h,sycl::read_only);

        sycl::accessor y_acc(y_buffer, h, sycl::write_only,sycl::no_init);

        h.parallel_for(sycl::range<2>(rows, cols), [=](sycl::id<2> idx) {

            int i = idx[0];

            int j = idx[1];

            y_acc[i][j] = 0.0;

            for (int k = 0; k < b.size(); k++) {

                if (i - k >= 0) {

                    y_acc[i][j] += b_acc[k] * x_acc[(i - k) ][j];

                }

            }

            y_acc[i][j] /= a;

        });

    });

    q.wait();

    return y;

}

Hi,

Thanks for posting on Intel communities.

Since this is a duplicate thread of https://community.intel.com/t5/Intel-oneAPI-Data-Parallel-C/oneapi/m-p/1508594#M3185, we will no longer monitor this thread. We will continue addressing this issue in the other thread.

Thanks & Regards,
