Depressing performance on a cross-correlation benchmark
by Yury V. Zaytsev 06 May '14

06 May '14

Hi folks, Yesterday, I was able to make my simple cross-correlation script to work with PyPy / NumPy at all with the valuable help of bdk, however, I ended up being quite disappointed about the performance. I stripped out everything I could and ended up with something like this: Python 3: $ time python corrbench.py 0 1 2 real 0m2.225s user 0m1.980s sys 0m0.240s PyPy from hg / NumPy from hg (3581f7a906c9+): $ time python corrbench.py 0 1 2 real 1m2.928s user 1m2.460s sys 0m0.270s What this script does, it basically generates two time series of ~5 000 elements and bins them into 3 000 000 buckets, which it then multiples element-wise and sums up the result. I expected a huge performance boost, of course :-) I think I'll be running this with plain Python for now, but I hope that's a valuable benchmark for you guys! -- Sincerely yours, Yury V. Zaytsev

PyPy 2.3 alpha release
by matti picus 05 May '14

You have been chosen by an advanced algorithm to participate in the alpha release of PyPy 2.3. Well, not so advanced, but please try it out, I want to release over the next few days. The remaining issues are: - rumors of the python 3.4 ensurepip module appearing in pypy - the macos build has a test failure in the openssl app-level version test Please let me know ASAP if your favorite feature is missing http://buildbot.pypy.org/nightly/release-2.3.x I would also appreciate help with the release notice, the name "Easier Than Ever" is as lame as this email but that's the best I could do. http://doc.pypy.org/en/latest/release-2.3.0.html Matti

release 2.3 and macos stdlib test failure
by Matti Picus 02 May '14

02 May '14

The macos buildbot, names xerses, has a consistent test failure. It appears to be a configuration error of the buildbot. The owner of the buldbot has not responded on IRC. Could someone else build a macos version off the release branch release-2.3.x that does not exhibit this failure and ships the same OpenSSL as cpython on macos? The failing test is in lib-python.2.7.test.test_ssl, http://buildbot.pypy.org/summary/longrepr?testname=unmodified&builder=pypy-… Matti
