| Abstract: | Dynamic load balancing is an important technique when developing applications with unpredictable load distribution on distributed memory multicomputers. A tool, Dynamo, that can be used to utilize dynamic load balancing is presented. This tool separates the application from the load balancer and thus makes it possible to easily exchange the load balancer of a given application and experiment with different load balancing strategies. A prototype of Dynamo has been implemented in the C language on an Intel iPSC/2 Hypercube. Dynamo is demonstrated by two example programs. The first program solves the N queen problem using a backtracking algorithm and the second solves a 0-1 knapsack problem using a depth-first branch and bound algorithm. |
