        Hi,

        I want to make the Rosetta 3.4 paralleled. But I have installed the ordinary one previously.

        Do I need to uninstall it and then install the MPI one? If so, is there a command to uninstall Rosetta, or I just need to delete the rosetta folder?

        I know I just need to add “extras=mpi” in the command.

        Thanks for your help!

          All you need to do is recompile. Rosetta will compile the MPI version into a different, independent location in your build folder and add “mpi” to the executables in the bin/ folder so you know which to use. The old, single-threaded ones will still work, and say “default” instead of “mpi”. For example, you’ll have fixbb.default.linuxgccrelease, and fixbb.mpi.linuxgccrelease. (The version with no “default” or “mpi” is whichever was built most recently).
