high performance computing on graphics processing units: hgpu.org

Advection is the transport of a quantity due to fluid flow, and is an important, computationally intensive part of any fluid simulation. OpenACC GPU acceleration of the advection components of MONC, an atmospheric LES, was pursued. Although this yielded no speedup, the reasons for this are examined, and the conditions under which it may become achievable are considered. OpenACC’s usability is also evaluated.
