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

How about [gromacs](http://www.gromacs.org). From `apt-cache rdepends libopenmpi1.3` on Debian system, which lists quite a lot. – Flexo Sep 19 '11 at 16:34

Applications are written to the MPI standard, not a particular implementation of MPI, of which Open MPI is but one. If you have misunderstood what Open MPI is, i.e. confused it with the MPI standard, then please submit a new question that is more appropriate. – Jeff Hammond Dec 23 '14 at 01:51

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.

The point I'm making is an application uses **MPI**, it doesn't use OpenMPI (which is simply an implemenation of OpenMPI). Unless you mean [OpenMP](http://openmp.org/wp/)? – Shawn Chin Sep 19 '11 at 16:48

AMBER, Gromacs is what I want. I mean OpenMPI(www.open-mpi.org) – Davit Siradeghyan Sep 19 '11 at 16:53

AMBER, GRomacs, etc are parallelised using MPI. They can be run using any of the MPI implementations (MPICH2, OpenMPI, LAM-MPI, ScaliMPI, Intel MPI, ... ) – Shawn Chin Sep 19 '11 at 16:55

Well, you could search for MPI benchmarks. There are several popular ones such as NAS, PALLAS, SPEC, etc.
