              <p class="">Hi everyone,</p>
              <p class="">I am currently debugging some code and have
                been printing out (using either CCTK_INFO and/or printf)
                debugging information at particular grid points (LOCAL
                mode).</p>
              <p class="">From what I can tell, Cactus only allows
                output from one process, say rank 0, to stop flooding of
                the output by printing everything once per process.
                However if I am wanting data from a particular grid
                point, and this grid point is not in the printing
                process, nothing will output.</p>
              <p class="">I have been getting around this by turning off
                MPI (fine for one iteration or so) but now I am doing
                longer runs I need to be able to print out this
                information with MPI.</p>
              <p class="">Thus my question:</p>
              <p class="">How can you force Cactus to print out a
                statement from any process?<br class="">
              </p>

          separate output and error files from each process.</div>
