Abstract

This paper presents an MPI implementation that allowsan easy and efficient use of the interconnection of severalclusters, of potentially heterogeneous nature (as far as thenetwork is concerned).We describe the underlying communicationsubsystem used.The mechanisms within MPI thatinform the user of the underlying topological structure aredetailed.The performance figures obtained with this MPIimplementation are discussed and advocate for the use ofsuch a solution on this particular type of architecture.
