   I just killed the process after 125 minutes; most of that time was stuck
on 0% completion at the stage, "Local TPS interpolation with 58 points ..."
on a fast workstation.

   The module command line included the input and output file names and the
column name with the precipitation data to be interpolated.

   What running time can I expect? How can I find why it's so slow?
