The integrated library approach to parallel computing

This paper describes preliminary work on the development of a language implementation technique that integrates the compilation of user level code with a special hierarchical library. To demonstrate this system, we have designed a Fortran77-based high level language (called MF) that does not permit the programmer to manage work or data distribution. For the system to be effective, the programmer must make calls to the library. At each call site, the compiler is provided with information about potential distributions for each of the variables involved. Our approach is intended to be used to gather empirical data about the portability and efficiency of specific programs written in MF and how their distribution requirements vary from machine to machine
