Abstract

While software architectures have been shown to aid developers in maintenance, reuse, and evolution as well as many other software engineering tasks, there is little language-level support for these architectural concepts in scientific programming languages such as Fortran and C. Because many existing scientific codes are written in legacy languages, it is difficult to integrate them into architected software systems. By wrapping scientific codes in architecturally-aware interfaces, we are able to componentize legacy programs, integrating them into systems built with first-class architectural elements while meeting performance and throughput requirements of scientific codes.
