This is probably wrong...

In

  void finish_distribution(const uint64_t n, particle_t p[const n])

you could just use particle_t p[] or if you are courageous sycl::span from SYCL 2020.

d = sycl::default_selector{}.select_device();

is the old weird Java-like factory from SYCL 1.2 which has been removed. Now you can just use

d = sycl::device { sycl::default_selector_v };

or probably in the case of the default selector which select the default device, just:

d = {};
