Expand description

GPU-accelerated SPH density summation.

Simulates a GPU kernel where each “thread” computes the density contribution from all neighbours within the smoothing radius h. In a real GPU implementation this would be launched as one thread per particle pair with atomic accumulation. Here we use a parallel-style double loop and write results into a temporary buffer first to keep the interface identical to a real GPU dispatch.
