Sorry if this evoked expectations, as I fell into the same trap: Compact objects seem to be very correct, since they pass so many tests. But the problem remains, that they tend to crash Psyco. And this is unfortunately still the truth, or even more than before, because I'm now very confident: The re-spawn/promotion engine cannot yet stand the demands of compact objects. Those need promotion on every access, which should not be a problem, but it is. This problem still needs to be solved. Sorry about this. I will implement a completely compact-free version of generators, which is anyway much more efficient and the way to go. The problem of making compacts usable still is very high on my priority list, and I will try again, after I have perfect generators. Concluding: I seemed to suffer three bugs, and one is still left. all the best - chris -- Christian Tismer :^) <mailto:ti...@st...> tismerysoft GmbH : Have a break!

This is not an official announcement of Psyco V2, yet. But everybody who is interested should check out http://codespeak.net:/svn/psyco/v2 and do some testing. The major improvement besides lots of builtins is the new generator support, which is disabled by default, due to an internal error in Psyco. To use and test generators, create preferences.py, following the instructions in setup.py. This software is considered asan alpha release. The final version should be expected before end of February. regards -- chris -- Christian Tismer :^) <mailto:ti...@st...> tismerysoft GmbH : Have a break!

Hi folks, this is not an official announcement, but just a note for people wondering about a series of check-ins on a path called psyco/v2. This is gonna be a new psyco version, to be released in a few days. Please note that psyco/v2 is maintained by me, not Armin. All requests concerning this version should be directed to me. Honors and authorship are of course staying to belong to Armin. More info is about to come soon, as well. cheers - chris -- Christian Tismer :^) <mailto:ti...@st...> tismerysoft GmbH : Have a break!

It cannot make a difference there, because this program is not running a lot of Python code at all. The loop only executes 20000 times, which doesn't take much time in CPython anyway. Instead, all the time is spent allocating and multiplying very large 'long' objects, and Psyco cannot do better than the 'long' multiplication code written in C in CPython. Armin |

Thank you, Armin! I'd completely forgotten that. This time my code was: ====================== import psyco, time psyco.full() from math import log as ln def test(): for x in xrange(5000000): ln(640320**3 + 744)/163**.5 timeStart = time.time() test() timeEnd = time.time() print "Time was %.4g seconds" % (timeEnd - timeStart) print "%.15f" % (ln(640320**3 + 744)/163**.5) """ with psyco 1.938, 2.078, 2.203 without 4.578, 4.61, 4.625 """ =========================== So a nice speed-up with psyco, 2X+.

Sometimes psyco speeds up a script by a factor of 10, and sometimes it makes no difference at all. Here's a case where I fully expected it to make a difference: <http://www.rcblue.com/Python/Psyco_Puzzle.txt>. Whether using psyco or not, this takes about 13 seconds on my computer. Why no difference? Here's a script where psyco makes a big difference: <http://www.rcblue.com/Python/2primes1-a2.py>. 1.8 seconds with psyco, vs. 12.7. without.seconds.

The project doesn't evolve a lot any more; I consider it finished. It's
certainly not "finished" in the sense that a lot more work could go into
it to support more things, or port it to other architectures, but what
is there works well so far. I am now working on PyPy instead, which -
after three years of work - might soon give more results than Psyco
alone could.
Indeed, I suppose I should announce here that we just got our first
version of PyPy with included Psyco-like just-in-time specialization :-)
