Hi Andrew, Please look at the latest documentation: https://bitbucket.org/pypy/pypy/raw/stm-thread/pypy/doc/stm.rst
You should be able to use such a "thread.atomic" in stackless.py. You need to create N threads and run the tasklets in these threads. As long as each tasklet's user code is protected by a "thread.atomic", then they will *appear* to be run serially. You probably need to call "thread.atomic.__enter__" and "__exit__" explicitly for your use case; if you do, then I could also move the functionality as normal built-in method. You also have to handle issues like tasklets not being always allowed to switch threads. As a first approximation, on CPython you can implement a dummy "thread.atomic" by acquiring and releasing a single lock. It is only an approximative equivalent because other non-atomic threads will be allowed to run concurrently; but for this kind of experiment where *all* threads should be "atomic", it should not make a difference. A bientôt, Armin. _______________________________________________ pypy-dev mailing list pypy-dev@python.org http://mail.python.org/mailman/listinfo/pypy-dev
