Concurrent C++: Concurrent Programming with Class(es)

C++ and Concurrent C are both upward-compatible supersets of C that respectively provide dataabstraction and parallel programming facilities. Although data abstraction facilities are important forwriting concurrent programs, we did not provide data abstraction facilities in Concurrent C because we didnot want to duplicate the C++ research effort. Instead, we decided that we would eventually integrate C++and Concurrent C facilities to produce a language with both data abstraction and parallel programmingfacilities, viz., Concurrent C++. Data abstraction and parallel programming facilities are orthogonal.Despite this, the merger of Concurrent C and C++ raised several integration issues. In this paper, we will give introductions to C++ and Concurrent C, give two examples illustrating theadvantages of using data abstraction facilities in concurrent programs, and discuss issues in integrating C++and Concurrent C to produce Concurrent C++.
