MPICH/Madeleine: a true multi-protocol MPI for high performance networks

Abstract
This paper introduces a version of MPICH handling eficiently different networks simultaneously. The core of the implementation relies on a device called ch_mad which is based on a generic multiprotocol communication library called Madeleine .The performance achieved with tested networks such as Fast-Ethernet, Scalable Coherent Interface or Myrinet is very good. Indeed, this multi-protocol version of MPICH generally outperforms other free or commercial implementations of MPI.
