Software Development Kaapi Kaapi is a C++ library that allows to execute multithreaded computation with data flow synchronization between threads. The library is able to schedule fine/medium size grain programon distributed machine.Contributions: Heterogeneous communications; Fault-tolerance mechanisms; Static scheduling module; Deployment organization; Dynamic reconfiguration concepts.http://kaapi.gforge.inria.frMVAPICH2 MVAPICH2 is a high performance MPI-2 implementation for InfiniBand, 10GigE/iWARP and RDMAoE based on MPICH2.Contributions: Fault-tolerance and migration mechanisms; Virtual filesystems for Checkpoint/Restart; Launcher evaluation and improvement http://mvapich.cse.ohio-state.edu/
DPM The Discrete Particle Method (DPM) is an advanced numerical simulation tool which deals with both motion and chemical conversion of particulate material such as coal or biomass infurnaces.Contributions: Parallelization for both conversion and dynamics modules; Improved designhttp://dpm.gforge.uni.lu/
