[Ilugc] Query on Gromacs Installation

[Gowriishankar Raju]

Dear friends,
I am using Ubuntu 9.10.
I want to work on Gromacs.
I have a query on installing the Gromacs on ubuntu.
How to choose the Gromacs version to be install in Ubuntu?
Is any special Gromacs versions available for ubuntu?
And what is the purpose to install FFTW?
Shall i use the latest version of FFTW to install?
Should the versions of FFTW and Gromacs be the same? (Like FFTW 3.2.2 V and
Gromacs 3.2.2V)

Please anybody help me to install as early as possible.
Waiting for your valuable suggestions.

Thanks in advance.

With Regards,
Gowriishankar Raju
