GROMACS version:  
GROMACS modification: Yes/No  
Here post your question  
Hi, we will be using gromacs for MD simulation as our thesis. What will be the recommended system requirements to run a simulation. Thank you.

Hi Sandovalelj,

The minimum requirements to run GROMACS at all are _very_ low. You might find fulfilling software requirements to run a simulation harder to fulfill than to find hardware where to run GROMACS.

However, to achieve scientifically meaningful results, the hardware requirements can easily become huge. To get a feel for how much your computer has to work to run a simulation, I suggest you try the [Lysozyme in Water](http://www.mdtutorials.com/gmx/lysozyme/01_pdb2gmx.html) tutorial.

If you have ubuntu, installing gromacs to just play with it is easily done with entering `apt install gromacs` at a command line, though this will not give you the highest performance, it gives you something to start.

For optimal performance, follow the [Installation guide — GROMACS 2020.5 documentation](https://manual.gromacs.org/documentation/current/install-guide/index.html)  
and get the latest software version here: [Downloads — GROMACS 2020.5 documentation](https://manual.gromacs.org/2020.5/download.html)

For a small thesis project, a workstation with a recent nvidia consumer GPU should give you the compute power to draw some conclusions on a small protein.
