495. Briefly: gromacs 4.6 on ROCKS 5.4.3

I didn't want to spend much time on getting this right, so I took the easiest route and combined three posts:

Firstly, I compiled cmake:

Secondly, I used the openblas libraries which I compiled in this post
http://verahill.blogspot.com.au/2013/05/421-nwchem-63-on-rocks-543centos-56.html

Thirdly, I looked at this post which deals with gromacs 4.6 on debian:

gromacs 4.6 can download and build its own fftw libs, so you don't need to do that separately.

First make the target directory, e.g.

sudo mkdir /share/apps/gromacs
sudo chown $USER:$USER /share/apps/gromacs

Single precision:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/openmpi/lib:/share/apps/openblas/lib
export LDFLAGS="-L/share/apps/openblas/lib -lopenblas"
export CPPFLAGS="-I/share/apps/openblas/include"

export CC=/usr/bin/gcc44
export CXX=/usr/bin/g++44
cmake -DGMX_FFT_LIBRARY=fftw3 -DGMX_BUILD_OWN_FFTW=On -DGMX_DOUBLE=off -DCMAKE_INSTALL_PREFIX=/share/apps/gromacs/gromacs4.6_single -DGMX_EXTERNAL_BLAS=/share/apps/openblas/lib ../gromacs-4.6
make
make install

Double precision:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/openmpi/lib:/share/apps/openblas/lib
export LDFLAGS="-L/share/apps/openblas/lib -lopenblas"
export CPPFLAGS="-I/share/apps/openblas/include"

export CC=/usr/bin/gcc44
export CXX=/usr/bin/g++44
cmake -DGMX_FFT_LIBRARY=fftw3 -DGMX_BUILD_OWN_FFTW=On -DGMX_DOUBLE=on -DCMAKE_INSTALL_PREFIX=/share/apps/gromacs/gromacs4.6_double -DGMX_EXTERNAL_BLAS=/share/apps/openblas/lib ../gromacs-4.6
make
make install

In my particular case I've got all users as members of the compchem group:

chown $USER:compchem /share/apps/gromacs -R 
chmod g+rwx /share/apps/gromacs -R
