I did as suggested adding the line
Parallelism().set(nproc=4)
before the contraction, but it behaves strangely: it works for a short while
with 4 processors, then with 3, then with 2 and finally it works for hours with
a single processor.
It seems that no new packages are distributed between the processors.
