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.
