If you mean for your personal computer, you need a proper version of Linux (Either Ubuntu or Fedora). It is been a while that I am using Ubuntu (upgraded regularly) and I didn't have any problem. But I you are talking about a cluster or super computer that you want to use, most of them are running on Linux and for you to connect them there is no limit on your OS. Install a SSH program and you are good to go.
In my opinion, one of the best Operating Systems for you is Ubuntu. I have used Ubuntu to design a cluster and also used MPI. It worked perfectly. Since LAMMPS uses MPI, Ubuntu might be your perfect choice.
It works perfectly on any Unix or Linux based OS. Personally, I prefer Ubuntu for the PC and CentOS or Fedora for the HPC. Installing the fftw and mpi library are pretty straight forward in any of the above OS.
