Jut follow them and add the repo.

Install 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>

int main()
{
	sycl::queue q{sycl::gpu_selector_v};
	
	float * data = sycl::malloc_shared<float>(37, q);
	
	q.parallel_for(
		37,
		[=] (sycl::item<1> item)
		{
			sycl::id id = item.get_id();
			data[id] = sycl::sqrt<float>(id);
		}
	);
	q.wait();
	for (int i=0; i<37; ++i)
		std::cout << data[i] << ' ';
	std::cout << std::endl;
	
	sycl::free(data, q);
}

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
