Abstract
This paper describes a first approach to implement MPI-2’s Extended Collective Operations. We aimed to ascertain the feasibility and effectiveness of such a project based on existing algorithms. The focus is on the intercommunicator operations, as these represent the main extension of the MPI-2 standard on the MPI-1 collective operations. We expose the algorithms, key features and some performance results. The implementation was done on top of WMPI and honors the MPICH layering, therefore the algorithms can be easily incorporated into other MPICH based MPI implementations.
