How can I solve this problem?

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,
