WebSince the Cython bindings do not require the GIL, it is easy to run them in parallel using Cython’s prange function. For example, suppose that we wanted to compute the fundamental solution to the Helmholtz equation: Δ x G ( x, y) + k 2 G ( x, y) = δ ( x − y), where k is the wavenumber and δ is the Dirac delta function.
