NewMadeleine is the fourth incarnation of the Madeleine communication library. The new architecture aims at enabling the use of a much wider range of communication flow optimization technics. Its design is entirely modular: drivers and optimization strategies are dynamically loadable software components, allowing experimentations with multiple approaches or on multiple issues with regard to processing communication flows. The optimizing scheduler SchedOpt targets applications with irregular, multi-flow communication schemes such as found in the increasingly common application conglomerates made of multiple programming environments and coupled pieces of code, for instance. SchedOpt itself is easily extensible through the concepts of optimization strategies (what to optimize for, what the optimization goal is) expressed in terms of tactics (how to optimize to reach the optimization goal). Tactics themselves are made of basic communication flows operations such as packet merging or reordering.
NewMadeleine is available on various networking technologies:
- Infiniband (ibverbs)
- Myrinet (MX and GM)
- TCP (sockets)
- legacy: SCI, Quadrics QsNet-2
It has been tested with Linux on IA32, IA64 and x86-64 architectures, and with MacOs/X on PowerPC architectures.
This library is developed and maintained by Alexandre Denis, Nathalie Furmento and Raymond Namyst. The software is freely available under the terms of the GNU General Public License version 2 as part of the PM2 project on INRIA Gforge.
