[gmx-users] Installing gromacs 5.0.2 double precision with shared fftw libraries

[Johnny Lu]

Or, just let it build its own fftw3?

cmake ${SOURCE_DIR} \
 -DCMAKE_INSTALL_PREFIX=${INSTALL_DIR} \
-GMX_BUILD_OWN_FFTW=ON \
  -DCMAKE_PREFIX_PATH="/global/software/boost/gcc" \
 -DGMX_DOUBLE=on \
 -DGMX_CPU_ACCELERATION="SSE4.1"

What compilers and cpu are you using?
