AdaptiveCpp: Eigen not working on hipSYCL sample code

I have tried to run a very simple SYCL code that uses EIgen, but fails to compile with cuda backend.

Code is the following:

#include <Eigen/Core>

int main() {
  Eigen::Vector4d a = Eigen::Vector4d::Random();
  Eigen::Vector4d b = Eigen::Vector4d::Random();
  Eigen::Vector4d c = Eigen::Vector4d::Random();

  cl::sycl::default_selector deviceSelector;
  cl::sycl::queue queue(deviceSelector);
  {
    cl::sycl::buffer<Eigen::Vector4d, 1> a_sycl(&a, cl::sycl::range<1>(1));
    cl::sycl::buffer<Eigen::Vector4d, 1> b_sycl(&b, cl::sycl::range<1>(1));
    cl::sycl::buffer<Eigen::Vector4d, 1> c_sycl(&c, cl::sycl::range<1>(1));

    queue.submit([&](cl::sycl::handler& cgh) {
      auto a_acc = a_sycl.get_access<cl::sycl::access::mode::read>(cgh);
      auto b_acc = b_sycl.get_access<cl::sycl::access::mode::read>(cgh);
      auto c_acc =
          c_sycl.get_access<cl::sycl::access::mode::discard_write>(cgh);

      cgh.single_task<class vector_addition>(
          [=]() {});  // c_acc[0] = a_acc[0] + b_acc[0]; });
    });

    // sycl buffers go out of scope and content is copied to host data
    // Are they copied also for a and b which havent changed?
  }

  std::cout << "  A { " << a.x() << ", " << a.y() << ", " << a.z() << ", "
            << a.w() << " }\n"
            << "+ B { " << b.x() << ", " << b.y() << ", " << b.z() << ", "
            << b.w() << " }\n"
            << "------------------\n"
            << "= C { " << c.x() << ", " << c.y() << ", " << c.z() << ", "
            << c.w() << " }" << std::endl;

  return 0;
}

and it fails with the following compilation errors

To my understanding, Eigen supports clang cuda (https://gitlab.com/libeigen/eigen/-/issues/1173), and in my test code, I dont even use eigen types in a kernel (kernel is empty).

Right. If there’s no code inside a kernel, then I’m not sure how hipSYCL could trigger those CUDA issues. I would still recommend checking if you can compile a CUDA version of the same code with clang to narrow down the issue. It might be that clang is not as well tested and there’s a regression in Eigen, or that it used to work and only newer clang versions cause trouble etc…

If Eigen also supports SYCL backend, could it be that is trying somehow to enable both CUDA backend and SYCL backend for Eigen?

I think this is exactly what is happening. See https://gitlab.com/libeigen/eigen/-/blob/master/Eigen/src/Core/util/Macros.h

The assumption inside Eigen that code is either SYCL or CUDA is not correct, since a SYCL implementation might sit on top of CUDA, as hipSYCL odes.

I am not sure your workaround is a good idea, since Eigen defines vectors with different padding depending if it detects CUDA compiler or not, so trying to tweak it may open a can of worms.

I would say, our goal should be to have it treat the vector like a SYCL vector and not like a CUDA one, hence my workaround. It seems you can also disable CUDA in Eigen with the macro EIGEN_NO_CUDA, so this might also be worth a try.
