Collection Level Polymorphism : A path to High Performance C + + Applications Edward

In this paper we present a C++ implementation of a numerical solver for the Euler equations about rotating geometries (Turbomachinery). This implementation represents a working prototype C++ solver which obtains performances comparable to a reference Fortran application. We obtain this performance by providing abstractions at the level of collections of objects , thus minimizing the introduction of \mid-level" 3] code. In this abstraction we implement a collection level polymorphism that is applicable to a broad range of Finite Element/Finite Volume based numerical solution methodologies. In addition, we discuss a potential extension of this abstraction to optimization of memory hierarchy utilization.
