Question

Please help me to find some working application which is using openmpi. I need any name of application which have widely/worldwide usage and based on openmpi (using it). At least the name of that kind application will be enough.

Thanks

Answer 1

OpenMPI is an implementation of MPI. Applications are written using MPI (i.e. the code calls MPI routines), and they can be compiled/run using any MPI implementation (e.g. MPICH2, OpenMPI, LAM-MPI, etc).

So, to answer your question, strictly speaking there is no such thing as an “OpenMPI application”.

As for what applications use MPI, there are many. Here’s a few:

• AMBER (Molecular Dynamics)
• Gromacs (Molecular Dynamics)
• DL-POLY (molecular dynamics)
• FFTW (for parallel Fourier transform)
• MATLAB Parallel Computing Toolbox
• FLAME (Agent-based modelling)
• CASTEP (Materiam science)
• POLCOMS (Marine Ecosystem)
• WRF (Weather Forecast)
• NWCHEM (Computational Chemistry)

… and the list goes on and on.
