Implementation of an object-oriented functional language on the multithreaded architecture

We suggest a new object-oriented functional language, OOId, which is based on a functional language Id and extended with object-oriented language features. We also discuss how to map OOId program onto DAVRID, which is a kind of multithreaded architecture based on the dataflow model. The comparison of execution time of two programs written in Id and OOId for the matrix multiplication problem, shows we can effectively run OOId program with just a little slow-down of execution time. In addition, the rate of slow-down is decreased, as the size of the matrix is larger. That means we can use good features of object-oriented language by paying just a little slow-down of execution time.
