Hi Taavi, I finally fixed pypy-stm with signals. Now I'm getting again results that scale with the number of processors.
Note that it stops scaling up at some point, around 4 or 6 threads, on machines I tried it on. I suspect it's related to the fact that physical processors have 4 or 6 cores internally, but the results are still a bit inconsistent. Using the "taskset" command to force the threads to run on particular physical sockets seems to help a little bit with some numbers. Fwiw, I got the maximum throughput on a 24-cores machine by really running 24 threads, but that seems wasteful, as it is only 25% better than running 6 threads on one physical socket. The next step will be trying to reduce the overhead, currently considerable (about 10x slower than CPython, too much to ever have any net benefit). Also high on the list is fixing the constant memory leak (i.e. implementing major garbage collection steps). A bientôt, Armin. _______________________________________________ pypy-dev mailing list pypy-dev@python.org http://mail.python.org/mailman/listinfo/pypy-dev
