LiBRA -- A load balancing tool for a reconfigurable parallel computer

Authors: Tambwekar, Sanjay, Shukla, U. S., Paulraj, A.


Load balancing in MIMD message-passing parallel computers is essential to make efficient use of the system resources and reduce the program runtime. For parallel computers that also provide topological ^configurability, it is necessary for the load balancing strategy to not only find an optimum distribution of tasks to processors, but also to determine the best-suited interconnection pattern for the processors. In this paper, we present an off-line tool, LiBRA, that will assist in automating the process of load balancing. The user specifies his problem in terms of a computation graph and the machine characteristics. LiBRA uses simulated annealing with an automatic annealing schedule to generate the optimal configuration.
