Using choreography of actors and rewriting rules to adapt legacy fortran programs to cloud computing

Abstract

We propose an approach to the semi-automatic transformation of legacy Fortran applications for execution on cloud computing platforms. The architecture is based on the choreography concept implemented as actor model, which allows to improve the scalability of the system and reduces overhead on message passing. The rewriting rules technique is used to formally define certain transformation steps. The approach is tested on an example program from the quantum chemistry field. The main contribution of this chapter is (1) using rewriting rules technique to automate transformation steps and (2) using service choreography to optimize resource allocation on the cloud.
