Implementing MPI-2 Extended Collective Operations



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
