high performance message passing library -- header files

 Open MPI is a project combining technologies and resources from several other
 projects (FT-MPI, LA-MPI, LAM/MPI, and PACX-MPI) in order to build the best
 MPI library available. A completely new MPI-2 compliant implementation, Open
 MPI offers advantages for system and software vendors, application developers
 and computer science researchers.
 This package contains the header files and compiler wrappers which are needed
 to compile and link programs against libopenmpi.
