Description
Summary:The paper presents a communication model of a set of heterogeneous processors interconnected via a switch-enabled Ethernet network. The goal of the model is to accurately predict the contribution of communication operations into the total execution time of parallel applications running on the platform. The presented model takes into account the impact of the heterogeneity of processors on the performance of communication operations. In this paper, we give analytical models for a single point-to-point communication, multiple independent point-to-point communications, multiple one-to-many point-to-point communications, and for a broadcast. Experimental results are presented demonstrating the accuracy of the analytical models
