    4647This memory information shows only the memory required by a single filter processes. In the example codes, this is the process with `mype_world=0`. One can also display the overall allocated memory by adding
    4748{{{
    48   IF (mype_world==0) CALL PDAF_print_info(11)
     49  CALL PDAF_print_info(11)
    4950}}}
    5051to the routine `finalize_pdaf`.
    … …  
    7576This timing display is particularly aimed at distinguishing the time spent in call-back routines from the time spent in PDAF-internal routines or PDAF-OMI internal routines. This timing information indicate those call-back routines that need particularly much time.
    7677
     78The timing information is for a single process. In the example codes, this is the process with `mype_world=0`. Without checking for `mype_world` one can let each process display its timing information.
     79
    7780Less detailed information cab be obtained using a value of 1, and more detailed information can be obtained using a value of 4 in the call to `PDAF_print_info`.
