[gmx-users] compiling paralel version

[Andre Farias de Moura]

Hi Andrei,

I just asked the same question and managed to compile mdrun
parallel version with the help from Oliver and David. The
script I used was as follows:

export  LAM_D=/usr/local/;
export FFTW_D=/usr/local/;

tar -jxvf lam-7.0.6.tar.bz2
cd lam-7.0.6
./configure --prefix=${LAM_D} --with-tcp-short=524288 --with-rpi=usysv
--with-rsh=ssh --with-shm-short=524288
make
make install

cd ..
tar -zxvf fftw-2.1.5.tar.gz
cd fftw-2.1.5

export PATH=${LAM_D}/bin:${PATH}   # so mpicc gets found

CPPFLAGS="-I${LAM_D}/include" \
LDFLAGS="-L${LAM_D}/lib" \
./configure --prefix=${FFTW_D} --enable-type-prefix --enable-mpi
--enable-float
make
make install

make distclean

./configure --prefix=${FFTW_D} --enable-type-prefix --enable-mpi
make
make install

cd ..
tar -zxvf gromacs-3.2.1.tar.gz
cd gromacs-3.2.1

CPPFLAGS="-I${LAM_D}/include -I${FFTW_D}/include" \
LDFLAGS="-L${LAM_D}/lib -L${FFTW_D}/lib" \

./configure
make
make install
make links

make distclean

./configure --without-x --enable-mpi --program-suffix=_mpi
make mdrun
make install-mdrun
make links

(end of script)

you just have to download lam-mpi and fftw from their
homepages and run a script like this (edit it to your
needs).

I hope it helps,

best regards,

andre'
