Multicast communication is one of the most significant collective communication operations and is highly demanded in data communications and scalable parallel and distributed computing systems. In this paper, we consider the issue of supporting multicast in the far and wide used well-known three-stage Clos network C(N, n, m; f2). We make use of Hwang??s unifying approach and Pattavina and Tesei??s...
The verification of termination is a difficult problem. While most of the recent work on automated termination proofs focuses on the construction of linear ranking functions for unnested loops, we present an algorithm based on region graphs to prove termination of nested loops. The method can prove the termination of terminating nested loops that may not have linear ranking function. For the programs...
