Compiling distributed C++

Distributed C++ (DC++) is a language for writing parallel applications on loosely coupled distributed systems in C++. Its key idea is to extend the C++ class into 3 categories: gateway classes which act as communication and synchronization entry points between abstract processors, classes whose instances may be passed by value between abstract processors via gateways, and vanilla C++ classes. DC++ code is compiled to C++ code with calls to the DC++ runtime system. The DC++ compiler wraps gateway classes with handle classes so that remote procedure calls are transparent. It adds static variables to value classes and produces code which is used to marshal and unmarshal arguments when these value classes are used in remote procedure calls. Value classes are deep copied and preserve structure sharing. This paper shows DC++ compilation and performance.
