Abstract

Cross-cluster load distribution of a parallel job has been studied in this paper. Two TeraGrid sites was pooled as a single resource to run 128 and 512 mesh blocks of a CFD problem having 18M mesh elements. Blocks were evenly distributed across the Grid clusters. Random block distribution was compared with two different distributions of graph partitioning. Interface size and block size were considered as weighting factors to group ...
