ICCSE Keynote Speech: Advances in Parallel Programming


While the Message Passing Interface (MPI) has been the dominant paradigm of choice for programming parallel applications, there has been much discussion about the inherent limitations of the message paradigm scheme. As a result, many new initiatives have been launched and initiatives have been taken. One promising directions has been that of the Partitioned Global Address Space (PGAS) programming model and its associated languages. This class of languages is characterized by its locality awareness and its one sided communications. Examples of the PGAS languages are Unified Parallel (UPC), Co-Array Fortran (CAF) and Titanium. In addition, the DARPA High-Productivity Computing Systems (HPCS) program is targeting systems, and consequently languages, that can minimize time-to-solution by 2010. Thus, both application development time and execution time are targeted for reduction. Two examples of the HPC languages are the X10, proposed by IBM, and Chapel, proposed by Cray. This talk will provide an overview of these new directions in parallel programming and will provide some insight into the benefits and challenges associated with these directions by examining some of the specifics of the UPC programming language.
