How to install EoMPI
|
|
====================
|
|
|
|
Install OpenMpi
|
|
---------------
|
|
|
|
1) Download OpenMPI on their website or with the following command:
|
|
|
|
wget http://www.open-mpi.org/software/ompi/v1.6/downloads/openmpi-1.6.tar.bz2
|
|
|
|
2) Untar the downloaded archive in a directory and change working directory to there:
|
|
|
|
tar -xvjf openmpi*.tar.bz2
|
|
cd openmpi-X.Y
|
|
|
|
3) Use configuration script to indicate in which directory OpenMPI should be installed, and other options:
|
|
|
|
Simplest configuration:
|
|
./configure --prefix=/home/`whoami`/openmpi/
|
|
|
|
Only static libraries:
|
|
./configure --enable-static --disable-shared
|
|
|
|
Only static libraries, with prefix, disable build for Fortran77 and Fortran90, add support for SGE:
|
|
./configure --enable-static --disable-shared --prefix=/home/`whoami`/openmpi/ --disable-mpi-f77 --disable-mpi-f90 --with-sge
|
|
|
|
Other options are available in the README file.
|
|
|
|
4) Make it and install:
|
|
|
|
In sequential:
|
|
make all install
|
|
|
|
Or in parallel:
|
|
make -j 2 all
|
|
make install
|
|
|
|
5) Try to compile and run the sample program:
|
|
|
|
~/openmpi/bin/mpicxx -o sample mpi.c
|
|
~/openmpi/bin/mpirun -np 3 ./sample
|
|
|
|
Configure EO to use MPI
|
|
-----------------------
|
|
|
|
You only need to configure eo-conf.cmake so as to use MPI :
|
|
|
|
1) Put the WITH_MPI boolean to true:
|
|
|
|
SET(WITH_MPI TRUE CACHE BOOL "Use mpi ?" FORCE)
|
|
|
|
2) Indicate in which directories you have installed openmpi:
|
|
|
|
SET(MPI_DIR "/where/did/you/install/openmpi" CACHE PATH "OpenMPI directory" FORCE)
|
|
|
|
3) Recompile eo:
|
|
|
|
./distclean
|
|
./build_gcc_linux_release.sh
|
|
|
|
4) If you meet any issue, don't hesitate to contact the EO mailing list:
