MPICH2 MPI with GNU compilers

MPI

For my understanding of what MPI is &/or does, please refer to this post.

Compiling MPICH2 (v1.3.1) with GNU Compilers (GCC v4.1.2)

1. mkdir $HOME/tmp/
2. Download MPICH2 from the Argonne National Laboratory
3. Save mpich2-1.3.1.tar.gz in $HOME/tmp/

4. cd $HOME/tmp/ tar -zxvpf mpich2-1.3.1.tar.gz cd mpich2-1.3.1   ./configure --prefix=$HOME/mpich2/1.3.1/gcc/4.1.2 --enable-f77 --enable-f90modules   make   make install

   cd $HOME/tmp/ tar -zxvpf mpich2-1.3.1.tar.gz cd mpich2-1.3.1 ./configure --prefix=$HOME/mpich2/1.3.1/gcc/4.1.2 --enable-f77 --enable-f90modules make make install

5. Once the make install} process is successfully completed, add the following lines to $HOME/.bashrc:

   export MPICH2="$HOME/mpich2/1.3.1/gcc/4.1.2" export PATH="${PATH}:${MPICH2}/bin:${MPICH2}/sbin" export MANPATH="${MANPATH}:${MPICH2}/man" export LD_LIBRARY_PATH="${MPICH2}/lib:${LD_LIBRARY_PATH}"   # Useful aliases/shortcuts alias mpicc="mpicc -g -Wall -lm" alias mpirun="mpirun -machinefile ${HOME}/machinefile"

   export MPICH2="$HOME/mpich2/1.3.1/gcc/4.1.2" export PATH="${PATH}:${MPICH2}/bin:${MPICH2}/sbin" export MANPATH="${MANPATH}:${MPICH2}/man" export LD_LIBRARY_PATH="${MPICH2}/lib:${LD_LIBRARY_PATH}" # Useful aliases/shortcuts alias mpicc="mpicc -g -Wall -lm" alias mpirun="mpirun -machinefile ${HOME}/machinefile"

6. Save and quit $HOME/.bashrc
7. Run the command. $HOME/.bashrc
8. Run the command:hostname > $HOME/machinefile
9. Parallel calculations can now be performed.
