Method for portable, scalable, and performant gpu accelerated simulation of multiphase compressible flow. This work presents a scalable and portable gpu accelerated computational framework for simulating multiphase flows with phase change. the solver addresses incompressible two phase flow by solving the navier–stokes equations and employs a direct fft based method for efficiently resolving the pressure field. It conducted the largest known public cfd simulation at 200 trillion grid points and 1 quadrillion degrees of freedom, scaling ideally to >43k amd apus on el capitan and >33k amd gpus on frontier.
