q4os kde linux install sycl cpp (dpcpp)

I will show you how to install dpcpp/cpp sycl c++ compiler on q4os kde linux.

Find the dpcpp apt repo

Browse this url to find the link to get sycl:

https://software.intel.com/dpcpp

(click Get It Now at that page)

Select repo

Select operating system: Linux

Select distribution: APT Package Manager

Then you will see how to add the intel software repo to your q4os linux. I am using q4os kde.

Jut follow them and add the repo.

Install dpcpp/cpp

Install sycl c++ dpcpp/cpp.

Update

apt update

Install

apt install intel-oneapi-compiler-dpcpp-cpp

Before installing it, you can search it:

apt search intel-oneapi-compiler-dpcpp-cpp

Write sycl cpp program

Write sycl c++ pogram, using dpcpp/cpp

sycl-prog.cpp

#include <sycl/sycl.hpp>
#include <iostream>
#include <vector>

int main()
{
	sycl::queue queue{sycl::gpu_selector_v};
	std::vector<float> data(37);
	auto buffer = new sycl::buffer<float, 1>{data.data(), data.size()};
	queue.submit(
		[&] (sycl::handler & handler)
		{
			auto in_accessor = sycl::accessor{* buffer, handler, sycl::read_write};
			handler.parallel_for(
				sycl::range<1>{data.size()},
				[=] (sycl::item<1> item)
				{
					sycl::id<1> id = item.get_id();
					in_accessor[id] = sycl::sqrt<float>(id);
				}
			);
		}
	);
	delete buffer;
	for (const auto & x: data)
		std::cout << x << ' ';
	std::cout << std::endl;
}

Then you can compile and run sycl code

You can use both dpcpp or icpx to compile the code:

Compile with dpcpp :

dpcpp sycl-prog.cpp -std=c++23 -o sycl-prog

Compile with icpx :

icpx -fsycl sycl-prog.cpp -std=c++23 -o sycl-prog

cpp/c++

c++ std::exception:

std::cout.write(err.data(), err.size());

std::cout << std::endl;
