| Abstract: | This paper provides a status report on the progress of research and development on the functional language Sisal. This project focuses on providing a highly effective method of writing large scientific applications that can efficiently execute on a spectrum of different multiprocessors. The paper includes sections on the language definition, compilation strategies, and programming techniques intended for readers with little or no background with Sisal. The section on performance presents our most recent results on execution speed for shared-memory multiprocessors, our findings using Sisal to develop codes, and our experiences migrating the same source code to different machines. For large programs, the execution performance of Sisal (with minimal supporting advice from the programmer) usually exceeds that of the best available automatic, vector/parallel Fortran compilers. Our evidence also indicates that Sisal programs tend to be shorter in length, faster to write, and dearer to understand than equivalent algorithms in Fortran. The paper concludes with a substantial discussion of common criticisms of the language and our plans for addressing them. Most notably, efficient implementations for distributed memory machines are lacking; an issue we plan to remedy. |
