Thanks for the answer, but I do not think setting OMP_NUM_THREADS is the
end of the story:
I did not set this variable myself before and when I launched my code in
a konsole I could get only 100% in agreement with the fact that it was
not set, but then why did I get 400 % when the same code (compiled and
linked identically with the same Makefile) was launched through eclipse ?
I think there is a default setting somewhere in eclipse that I would
like to find.
