% ./jx fe2.scfout jx.config > jx.logThe first argument should be a
scfoutfile generated by OpenMX. The second argument is the configuration file explained above.
Also, 'jx' supports the MPI parallelization for periodic calculations.
% mpirun -np 2 ./jx fe2.scfout jx.config > jx.logNote that MPI parallelization of `jx' is supported only for the eigenvalue solver `band' and not for `cluster'. We also have to note that the parallelization is done only for the vector, and when the parallelization number becomes larger than the total number of -points it would result in unnecessary consumption of computational resources.
