Interaction between MPI and TCP in grids. (2009)

Hablot, Ludovic, Glück, Olivier, Mignot, Jean-Christophe, Guillier, Romaric, Soudan, Sébastien

As MPI applications are more and more resource consuming, they need to be executed on grids. The communications on the WAN interconnecting clusters mostly use TCP which suffers from WAN features:...

Towards a User-Oriented Benchmark for Transport Protocols Comparison in very High Speed Networks (2007)

Guillier, Romaric, Hablot, Ludovic

Standard TCP faces some performance limitations in very high speed wide area networks, mainly due to a long end-to-end feedback loop and a conservative behaviour with respect to congestion. Many TCP...
