Abstract

The Open Run-Time Environment (OpenRTE)-a spin-off from the Open MPI project-was developed to support distributed high-performance computing applications operating in a heterogeneous environment. The system transparently provides support for interprocess communication, resource discovery and allocation, and process launch across a variety of platforms. In addition, users can launch their applications remotely from their desktop, disconnect from them, and reconnect at a later time to monitor progress. This paper will describe the capabilities of the OpenRTE system, describe its architecture, and discuss future directions for the project.
