Testing pypy
by Seung Soo, Ha Aug. 12, 2011

Aug. 12, 2011

http://docs.python.org/devguide/runtests.html Can I run tests on pypy as above? I downloaded the linux binary version for the pypy website (https://bitbucket.org/pypy/pypy/downloads/pypy-1.5-linux64.tar.bz2) running $./pypy -m test prints " No module named test.__main__; 'test' is a package and cannot be directly executed " (without a new line at the end!) Is this expected? Am I doing something wrong here?

jit-short_from_state
by Hakan Ardo Aug. 12, 2011

Aug. 12, 2011

Hi, what I had in mind for jit-short_from_state is now in place and seem to be working. So if anyone feels like reviewing now is a good time :) Benchmarks show ai 15% faster, spectral-norm 47% faster and bm_mako 11% slower as compared to trunk. The others are not affected much: http://paste.pocoo.org/show/455974/ There are still 3 test_pypy_c tests failing due worse optimization: http://buildbot.pypy.org/summary?branch=jit-short_from_state Addressing those would need some though … [View More]

Do we want to run our speed comparisons against 2.7 not 2.6 for the release? Laura

newbie needs pypy setup help
by Tom Roche Aug. 10, 2011

Aug. 10, 2011

(Apologies if - this is not the appropriate venue for this question, but I don't see any other pypy lists, and I'm finding the other docs a bit inscrutable. - I sound too inexperienced or unpythonic: I've spent most of my coding life in java and perl. ) Please advise how to configure pypy to run other python code. Why I ask: I've started running a model implemented in python. Unfortunately a run on "normal" python 2.6.x or 2.7.x requires - 130 min on my ubuntu laptop (on which … [View More]working would be more convenient) - 55 min on the best build machine to which I currently have access However I have read that this model runs 5x faster under pypy, so I wanna get me that! Unfortunately my current ubuntu me@it:~$ lsb_release -ds > Ubuntu 10.04.3 LTS # yes, I am planning to upgrade Real Soon Now me@it:~$ uname -rv > 2.6.32-33-generic #70-Ubuntu SMP Thu Jul 7 21:13:52 UTC 2011 is too down-level to install the available pypy RPM, so I instead did URI="https://bitbucket.org/pypy/pypy/downloads/pypy-1.5-linux64.tar.bz2" TMP_DIR_ROOT="/tmp/pypy" for CMD in \ "rm -fr ${TMP_DIR_ROOT}" \ "mkdir -p ${TMP_DIR_ROOT}" \ "pushd ${TMP_DIR_ROOT}" \ "wget -O - ${URI} | tar xvjf -" \ "ls -alh" \ "popd" \ ; do echo -e "${CMD}" eval "${CMD}" done # check path names, then TMP_DIR_ROOT="/tmp/pypy/pypy-c-jit-43780-b590cf6de419-linux64" TARGET_DIR_ROOT="/opt/pypy-c-jit-1.5.0-alpha0" TARGET_PYPY_EXEC="${TARGET_DIR_ROOT}/bin/pypy" USR_PYPY_EXEC="/usr/local/bin/pypy" for CMD in \ "sudo mkdir -p ${TARGET_DIR_ROOT}" \ "sudo cp -r ${TMP_DIR_ROOT}/* ${TARGET_DIR_ROOT}/" \ "sudo chmod 755 ${TARGET_DIR_ROOT}/" \ "sudo chmod 755 ${TARGET_DIR_ROOT}/bin/" \ "sudo chmod 755 ${TARGET_PYPY_EXEC}" \ "sudo ls -al ${TARGET_PYPY_EXEC}" \ "sudo ln -s ${TARGET_PYPY_EXEC} ${USR_PYPY_EXEC}" \ "sudo ls -al ${USR_PYPY_EXEC}" \ "${USR_PYPY_EXEC} --version" \ "which pypy" \ "pypy --version" \ ; do echo -e "${CMD}" eval "${CMD}" done The good news is, I can now me@it:~$ ls -al $(which pypy) > lrwxrwxrwx 1 root root 37 2011-07-30 16:06 /usr/local/bin/pypy -> /opt/pypy-c-jit-1.5.0-alpha0/bin/pypy me@it:~$ pypy --version > Python 2.7.1 (b590cf6de419, Apr 30 2011, 02:00:34) > [PyPy 1.5.0-alpha0 with GCC 4.4.3] But when I try to actually *run* the @#$%^&! thing, it spews: me@it:~$ pypy > debug: WARNING: library path not found, using compiled-in sys.path and sys.prefix will be unset > 'import site' failed > Python 2.7.1 (b590cf6de419, Apr 30 2011, 02:00:34) > [PyPy 1.5.0-alpha0 with GCC 4.4.3] on linux2 > Type "help", "copyright", "credits" or "license" for more information. > debug: OperationError: > debug: operror-type: ImportError > debug: operror-value: No module named _pypy_interact me@it:~$ pypy -c 'import sys; print sys.path' > debug: WARNING: library path not found, using compiled-in sys.path and sys.prefix will be unset > 'import site' failed > ['', '/home/buildslave/bot64/pypy-c-jit-linux-x86-64/build/lib_pypy', '/home/buildslave/bot64/pypy-c-jit-linux-x86-64/build/lib-python/modified-2.7', '/home/buildslave/bot64/pypy-c-jit-linux-x86-64/build/lib-python/2.7', '/home/buildslave/bot64/pypy-c-jit-linux-x86-64/build/lib-python/modified-2.7/lib-tk', '/home/buildslave/bot64/pypy-c-jit-linux-x86-64/build/lib-python/2.7/lib-tk', '/home/buildslave/bot64/pypy-c-jit-linux-x86-64/build/lib-python/2.7/plat-linux2'] What do I need to do to fix its library path?

PowerPC 64 bit support
by David Edelsohn Aug. 10, 2011

Aug. 10, 2011

Sven, Attached is a patch that adds 64 bit PowerPC instructions to ppcgen. The backend builds with this patch. I need to understand how to add tests that only run in 64 bit mode because the instruction will fail on a 32 bit PowerPC system as illegal instructions. Thanks, David

PPC backend design questions
by David Edelsohn Aug. 10, 2011

Aug. 10, 2011

The nop mnemonic is defined twice in ppc_assmbler.py: In class PPCAssembler # F.9 Recommended Simplified Mnemonics nop = BA.ori(rS=0, rA=0, UIMM=0) and in class PPCBuilder def nop(self): self.ori(0, 0, 0) Which one should be removed? I assume the one in PPCBuilder. Some PPC64 instructions have complicated encodings that split operands among multiple fields, such as shift immediate instructions, or truncates fields, such as load and store displacements. I … [View More]

file reading/writing speed
by Josh Ayers Aug. 9, 2011

Aug. 9, 2011

Sorry if this is a dumb question - I'm very new to PyPy, but also very interested in using it in several applications. I currently use PyTables and NumPy in a particular application, and I was playing around with the idea of migrating it to PyPy. I don't really need the querying or compression capabilities of PyTables, and most processing of the data is done in pure Python code, so I was hoping to see a speed-up with PyPy. I ran some tests yesterday on storing data on disk in flat binary … [View More]

PyPy at last infinitely fast
by Miquel Torres Aug. 7, 2011

Aug. 7, 2011

Hi, speed.pypy.org currently shows a very encouraging performance picture for PyPy: it is "infinite times faster than CPython". No, it is note yet April 1st. Codespeed creates the front page plots using the latest tested revision... which currently has no data for pypy-c-jit (32 bits). There is already a ticket for that issue, as well as to fix the Changes view letting you choose a revision with no data. The assumption was that a revision would be tested for all executables of a given project,… [View More]
