Abstract

The design and implementation of a CORBA load distribution service for distributed scientific computing applications running in a network of workstations is described. The proposed approach is based on integrating load distribution into the CORBA naming service which in turn relies on information provided by the underlying WINNER resource management system developed for typical networked Unix workstation environments. The necessary extensions to the naming service, the WINNER features for collecting load information and the placement decisions are described. A prototypical implementation of the complete system is presented, and performance results obtained for the parallel optimization of a mathematical test function are discussed
