Abstract	This paper presents a method for embedding arbitrary communication topologies into heterogeneous crossbar interconnection networks. Our methods extends and improves the method presented in [1] which is based on mathematical programming. It supports not only homogeneous but also heterogeneous networks with different interfaces. It has been applied to a crossbar network of parallel signal processor system consisting of 256 modules. It is shown that the optimization of the embedding algorithm leads to a considerable enhancement of the performance. Keywords: Configuration, embedding, parallel computing, heterogeneous networks. 1 INTRODUCTION The time to compute large scale applications on massive parallel computers depends crucially on the communication overhead caused by the data exchange between processors [2]. Thus a good match between the data dependencies defined by the application and the topology of the processor interconnection network is essential for an effective parallel proce...
