Madeleine II: a portable and efficient communication library for high-performance cluster computing

This paper introduces Madeleine II, a new adaptive and portable multi-protocol implementation of the Madeleine communication library. Madeleine II has the ability to control multiple network interfaces (BIP, SISCI, VIA) and multiple network adapters (Ethernet, Myrinet, SCI) within the same application session. Moreover it includes advanced mechanisms to dynamically select the most appropriate transfer method for a given network protocol according to various parameters such as data size or responsiveness user requirements. We report on performance measurements obtained using BIP/Myrinet and SISCI/SCI and we present preliminary results about our Nexus/Madeleine II and MPICH/Madeleine II ports.
