dtrace	Use '-n' instead of '-np' option in documentation, examples, and tests Signed-off-by: Christoph Niethammer <niethammer@hlrs.de>	4 年前
Makefile	Remove the Open MPI Java MPI bindings The Java MPI bindings were always experimental, were never part of the MPI standard, and are no longer maintained. Remove them in their entirety. Deleted: - the ompi/mpi/java tree (Java sources and the JNI C glue) - the mpijavac wrapper compiler (mpijavac.pl.in) - the Java example programs (Hello/Ring/Connectivity.java) - the LANL macosx-dynamic-java contrib platform files, whose sole purpose was building the Java bindings Removed the Java build machinery: the --enable-mpi-java configure option, the ompi_setup_java / ompi_setup_mpi_java m4 macros, the OMPI_WANT_JAVA_BINDINGS automake conditional and preprocessor define, the libmpi_java shared-library versioning, and the related Makefile.am hooks. Removed the now-dead Java op-callback infrastructure from ompi/op (the java_data union member, the OMPI_OP_FLAGS_JAVA_FUNC flag, the ompi_op_set_java_callback() setter, and the reduction dispatch branch). The "Java bindings" line in ompi_info is retained but hard-coded to "no" so anything parsing that field keeps working. Updated all documentation to drop references to the Java bindings, and added a v6.0.0 changelog entry recording the removal. Signed-off-by: Jeff Squyres <jeff@squyres.com>	2 个月前

The files in this directory are sample MPI applications provided both as a trivial primer to MPI as well as simple tests to ensure that your Open MPI installation is working properly.

If you are looking for a comprehensive MPI tutorial, these samples are not enough. Excellent MPI tutorials are available here.

Get a free account and login; you can then browse to the list of available courses. Look for the ones with "MPI" in the title.

There are two MPI examples in this directory, each using one of six different MPI interfaces:

Hello world

The MPI version of the canonical "hello world" program:

C: hello_c.c
C++: hello_cxx.cc
Fortran mpif.h: hello_mpifh.f
Fortran use mpi: hello_usempi.f90
Fortran use mpi_f08: hello_usempif08.f90
C shmem.h: hello_oshmem_c.c
Fortran shmem.fh: hello_oshmemfh.f90

Ring

Send a trivial message around in a ring:

C: ring_c.c
C++: ring_cxx.cc
Fortran mpif.h: ring_mpifh.f
Fortran use mpi: ring_usempi.f90
Fortran use mpi_f08: ring_usempif08.f90
C shmem.h: ring_oshmem_c.c
Fortran shmem.fh: ring_oshmemfh.f90

Connectivity Test

Additionally, there's one further example application, but this one only uses the MPI C bindings to test the connectivity between all processes:

C: connectivity_c.c

Makefile

The Makefile in this directory will build as many of the examples as you have language support (e.g., if you do not have the Fortran use mpi bindings compiled as part of Open MPI, those examples will be skipped).

The Makefile assumes that the wrapper compilers mpicc, mpic++, and mpifort are in your path.

Although the Makefile is tailored for Open MPI (e.g., it checks the ompi_info command to see if you have support for mpif.h, the mpi module, and the use mpi_f08 module), all of the example programs are pure MPI, and therefore not specific to Open MPI. Hence, you can use a different MPI implementation to compile and run these programs if you wish.

Make today an Open MPI day!
