 Implementing a Hardware-based Barrier in Open MPI

(In Proceedings of 2005 KiCC Workshop, Chemnitzer Informatik Berichte, presented in Chemnitz, Germany, ISSN: 0947-5152, Nov. 2005)


Open MPI is a recent open source development project which combines features of different MPI implementations. These features include fault toler- ance, multi network support, grid support and a component architecture which ensures extensibility. The TUC Hardware Barrier is a special purpose low la- tency barrier network based on commodity hardware. We show that the Open MPI collective framework can easily be extended to support the special purpose collective hardware without any changes in Open MPI itself.
