چکیده

Though data-parallelism addresses a wide variety of problems in scientiic computing, this model in inadequate for general adaptive applications. Coir is our object-oriented thread-based model for data and task parallelism 25, 22, 24]. In this paper we brieey discuss the Coir objects-thread objects for control-parallelism and groups of thread objects, called ropes, for data-parallelism. Using an example from the CMU-task-parallel suitee5], we discuss the eeectiveness of our model in terms of expressibility and eeciency.

Coir: A Thread-Model for Supporting Task- and Data- Parallelism in Object-Oriented Parallel Languages

Dataand task-parallelism are two important parallel programming models. Object-oriented paradigm in parallelism provides a good way of abstracting out various aspects of computations and computing resources. Using an object-oriented language like C++, one can compose data and control representations into a single active object. We propose a thread model of parallelism that addresses both data a...
