WARASA: an enhanced C++ for concurrent programming on shared memory multiprocessor computers

The authors propose an object-oriented programming language called WARASA for writing concurrent object-oriented program on Mach-based shared memory multiprocessor computers. WARASA is an extension to C⁺⁺ to allow a programmer to develop concurrent programming. In designing WARASA, the parallel mechanisms on the Mach operating system are combined with the object-oriented paradigm. It enables users to develop concurrent programs easily and efficiently, because some implementation details such as locking and unlocking which programmers would have to know to write parallel programs are hidden. An overview of WARASA is given. The features of WARASA class models are discussed. Some applications are shown to demonstrate WARASA´s expressive power
