    19 Although this makes me wonder about my hardware, I do recall having this kind of error (365 maps generated in parallel, and 1 or 2 rows in the entire set with corruption "discovered" by `r.series`) nearly every time I have used `r.sun` over the last 10 years. It just so happens that this time I am performing the same operation 54 times vs. the typical single run.

     21However, I recall having this kind of error (365 maps generated in parallel, and 1 or 2 rows in the entire set with corruption "discovered" by `r.series`) nearly every time I have used `r.sun` over the last 10 years. It just so happens that this time I am performing the same operation 54 times vs. the typical single run. In every situation I was using some version of Debian or Xubuntu on fairly common (multi-processor or multi-core) hardware.
