Productivity prediction of MPI programs based on models

A model of parallel program that can be effectively interpreted on the development computer guaranteeing the possibility of a sufficiently precise prediction of real run time for a simulated parallel program at the prescribed computer system is studied. The model is worked out for parallel programs with explicit message passing written in the Java language with MPI library access and is included into the composition of ParJava environment. The model is obtained by transforming the program control tree that can be constructed for Java programs by modifying the abstract syntax tree. To model communication functions, the model LogGP is used which allows taking into consideration the specific character of the communication network of the distributed computer system.
