CHARM

Abstract

CHARM is a machine independent parallel programming language. Programs written using this system will run unchanged on MIMD machines with or without a shared memory. It provides high-level mechanisms and strategies to facilitate the task of developing even highly complex parallel applications. Charm programs are written in C with a few syntactic extensions. It is possible to interface to other languages such as FORTRAN using the foreign language interface that C provides. Charm++ is the C++-based parallel object oriented language having all features of Charm, which supports multiple inheritance, late bindings, and polymorphism. Charm features include effficent portability, latency tolerance, and dynamic load balancing. The system provides support for both regular and irregular computations.
