Hi,
I have downloaded the pypy 1.5 binary (with jit) and run tests (only
sympy/core, so that it's fast) on Ubuntu Natty, 64bit:
ondrej@eagle:~/repos/sympy(master)$ bin/test sympy/core/
= test process starts ==
executable: /usr/bin/python

Hi,
I tried the pypy 1.2 linux binary with our latest sympy git and this
is what I got:

Exactly. That's what I wanted to ask you what's wrong. :)

Because as you can see above, the speed is imho only possible when
writing it in C. Well, if RPython could produce as optimized code as
Cython,
I couldn't say it better, completely agree with Martijn. It's fine, if
pypy is going to be a research project, but I was thinking for many
years, that the aim is to get a production interpreter. In fact, there
will be dozens people willing to help out, but pypy first needs to
solve 90% of things
Someone needs to show leadership and make a plan. There needs to be a
certain level of commitment to this plan from the project and project
Yes, this is really important.

From previous discussions, I suspect I'm not the only lurker-fan who would
be willing to commit time to working on numericentric graph optimizations
when that becomes a worthwhile investment. There's no reason that the
mostly-fortran bits of python code shouldn't run almost as fast as fortran

Hi,

Hi Armin,
Yes, os.tmpfile() was added in the meantime. I personally don't see
much the point of making Debian packages of PyPy at the moment, given
that we're in a state where you are almost always better off if you
start from our Subversion repository instead of from a release a few
months
Hi Armin,
That's obviously because the python path of pypy doesn't allow it to
find the 'py' module. You don't have this problem if you don't use the
globally-installed py.test, but the one from a PyPy checkout instead:
pypy .../pypy-dist/py/bin/py.test args...
or equivalently

We are confident that we can surpass CPython's speed with the help of

that plays well with threads. Boehm is not very good in this respect.
After this is done we can think about how to insert locking operations

Thanks for doing that! It's nice
