SUMMARY:Porting the astrophysical fluid dynamics application PROMPI to GPU

DESCRIPTION:PROMPI simulates convection and nuclear burning in stars. It i
 s a fully compressible\, Eulerian\, finite volume fluid dynamics stellar e
 volution simulator based on the piecewise parabolic method (PPM) hydrodyna
 mics scheme. It is based on the legacy astrophysics simulator PROMETHEUS a
 nd is fully parallelized using the domain decomposition method with messag
 e passing handled via the Message Passing Interface (MPI). In this softwar
 e engineering talk I shall describe the experience of porting PROMPI to us
 e GPUs and some early performance results from the new code. I will mostly
  present the initial state of the code and how I changed it to allow the a
 ddition of GPU code. This talk will not include any information about the 
 research and the physics background related to PROMPI.
