pypy-stm: not dead
by Armin Rigo June 16, 2014

June 16, 2014

Hi all, Just a quick note to tell you sorry: although the 2.3 release of PyPy said the release of PyPy-STM would occur very soon, it's still delayed. We have found some real use cases in which it is several times slower than PyPy (both with the JIT) and so we're busy setting up a few missing things with the GC, notably the card marking scheme, which we think is causing it.

wierd test failure when running tests in parallel
by Matti Picus June 15, 2014

June 15, 2014

on windows own build, tests that call ctypes2lltype with an Unsigned failed last night's build, for instance http://buildbot.pypy.org/summary/longrepr?testname=test_connect_ex&builder=… Running this test alone passes. Two questions 1. Should there be a fastpath like elif T is lltype.Unsigned: llobj = cobj 2. how can ctypes2lltype(Unsigned, 784L) fail? Note: I have started running two test processes in parallel, which may be creating many more open file handles. Matti

--sandbox woes. H ow do I install modules?
by Barry, John June 14, 2014

June 14, 2014

Hoping someone here can point me in the right direction. I'm attempting to create a sandbox, load it up with our requirements via pip, and start figuring out how to execute this from our codebase. It all falls down every single time when I attempt to install distribute.py, because import time fails within the sandbox. So the question is twofold: (1) How can I get import time working (as we call datetime.datetime.utcnow() with astonishing regularity) (2) How do I install additional packages … [View More]

PYPYLOG and colon as a special character
by Matti Picus June 13, 2014

June 13, 2014

if PYPYLOG is a filename, we log to it (except debug_print) if PYPYLOG is :filename, we log debug_print as well if PYPYLOG is section:filename, we log only that section But : is a valid char for filename on windows, so something like PYPYLOG=C:\TEMP\log.log does the wrong thing, and even worse, does so silently.

failing test for on windows
by Matti Picus June 12, 2014

June 12, 2014

We are down to the last 50 own tests on win32. Here is one I need help with: http://buildbot.pypy.org/summary/longrepr?testname=TestLowLevelType.%28%29.… The failure is that, like ARM, ssize == llmemory.sizeof(Signed) * 2 where ssize is 8 Is the test wrong or is there a problem with overallocating memory?

Matrix dot product
by Gayathri J June 11, 2014

June 11, 2014

Following is my python code for matrix multiplication *import time* *a=random.rand(1**28,128,128,15)* *b=np.random.rand(15,15)* *c=np.zeros((128,128,128,15), dtype=np.float64)* *t=time.time()* *c=a.dot(b)* *print time.time()-t* Timing for *pypy -> 3.957* *python 2.7 -> .80* So find that the basic matrix dot operation is faster on python 2.7 than on pypy 2.2.1 why is this so? am i missing something? thanks gayathri
