Timing test for nam1x1 zoom region

I'm going to test the run time for ten days of glb6x4+nam3x2+nam1x1 with coarsened meteo as a function of the number of threads, and archive the result here. Everything was run on a water-cooled ('normal') node of cartesius.

# of threads	Run time (over three runs)
1	0:03:52, 0:03:46, 0:03:48
2	0:02:49, 0:02:51, 0:02:51
3	0:02:28, 0:02:20, 0:02:19
4	0:02:02, 0:02:14, 0:02:11
5	0:02:05, 0:02:06, 0:02:05
6	0:02:02, 0:01:51, 0:02:03
7	0:01:48, 0:01:47, 0:01:48
8	0:01:44, 0:01:47, 0:01:45
