Many large and complex HPC simulation system consists of semi-independent program components developed by different groups or for different purposes. For example, climate system consists of atmosphere, ocean, land, sea-ice components. It is desirable to let the semi-indenpendent components remain standalone executables.
On distributed memory parallel supercomputers, each executable needs to find who are the other components, what's their names, their sizes and needs to initialize communication channels between independent components. These are among the first critical steps in establishing a distributed multi-component environment.
MPH, a multi program-component handshaking library,
resolves these tasks in a convenient and consistent way.
MPH uses MPI for high performance.
It is simple and easy-to-use.
One may simply adop it in
developing practical codes; or
one may use it as a basis for larger
software tools/frameworks.
