Date: Tue, 17 Jul 2007 10:11:00 -0000	[thread overview]

------- Comment #2 from theodore dot papadopoulo at sophia dot inria dot fr  2007-07-17 10:11 -------
And to reply to myself, it needs either to use thread local storage to hold the
counters and then to add some piece of code to fuse the values of the various
counters at the end of a thread (which might not be easy ?) or to use atomic
operations (which existence depends on the architecture, but I hope that all
multi-core processors have such instructions).
