Abstract

This paper describes an adaptive algorithm called ALBA (Adaptive Load Balancing Algorithm) for load balancing of irregular applications on parallel and distributed architectures. ALBA uses an adaptive centralized load information collection policy to maintain a global current load state in the machine. The transfer and location decisions are taken locally on each node of the architecture. A thread-based approach is used to implement ALBA on a farm of DEC/ALPHA processors. An application to a multithreaded IDA* program applied to the 15-puzzle problem is presented. An average speed-up of 14.8 has been obtained on the longest instances of the problem on a farm of 16 processors.
