-Note the use of ''mpirun -np 4'' together with the cp2k.popt executable. This tells the machine to run it using the MPI parallelization system on 4 cores, which should speed up your calculations. The prefix ''nohup'' lets the command continue even if you log out and the ampersand ''&'' makes it run in the background. Remember that tcopt2 is shared among you and that there is only a limited number of cores. You can use the command "topto check if there are enough cores available for your calculation.+Note the use of ''mpirun -np 4'' together with the cp2k.popt executable.
