Hi Moritz,
Terracost runs in two modes: in memory (when numtiles=1), and in
external memory, using streams (when numtiles>1). When run without a
value for numtiles, it sets numtiles to the optimal value. In all your
tests numtiles was set to 1. The algorithms in the 2 cases are
different, so you also need to test with numtiles>1.
Trying to run with numtiles>1, I get:

And the same, if I change all occurrences of /var/tmp in main.cc to /tmp
