1 . I am not sure as to how to set the full path in the cmake command line.
Do I need to use the export command to set the path ?
An example will be of great help. I am also searching the web but can not
find a satisfactory answer.
As highlighted in my step 5 ( trailing mail ) , I think install_prefix will
install the gromacs version in the specified directory or am I wrong ?
2. Yes , I understand it after reading the instructions. I think mdrun will
pick up MPI threading automatically.
I have also installed FFTW 3.0 in a local folder , how do I set its path in
the cmake command line and I also have gcc in the root folder , along with
Pardon my ignorance as I think these are very basic questions related to
the linux architecture.

Specify the full PATH of your cmake, otherwise the environment will just
pick up the default cmake on the cluster.
Also I would request the users to check my workflow of the installation

There is no point in compiling the whole suite of tools with MPI; nothing
makes use of MPI except mdrun. So if you want to compile all the tools
(preprocessing and analysis), don't set GMX_MPI. If you are using GMX_MPI,
then set -DGMX_BUILD_MDRUN_ONLY=ON to get MPI-enabled mdrun. Strictly
speaking, MPI is not required, but it depends on what you want to do
whether or not you need it.
