[Pytables-users] ANN: numexpr 2.1 RC1 available!

[Francesc Alted]

  Announcing Numexpr 2.1RC1


Numexpr is a fast numerical expression evaluator for NumPy.  With it,
expressions that operate on arrays (like "3*a+4*b") are accelerated
and use less memory than doing the same calculation in Python.

It wears multi-threaded capabilities, as well as support for Intel's
VML library, which allows for squeezing the last drop of performance
out of your multi-core processors.

What's new
==

This version adds compatibility for Python 3.  A bunch of thanks to 
Antonio Valentino for his excelent work on this.I apologize for taking 
so long in releasing his contributions.

In case you want to know more in detail what has changed in this
version, see:

http://code.google.com/p/numexpr/wiki/ReleaseNotes

or have a look at RELEASE_NOTES.txt in the tarball.

Where I can find Numexpr?
=

The project is hosted at Google code in:

http://code.google.com/p/numexpr/

This is a release candidate 1, so it will not be available on the PyPi 
repository.  I'll post it there when the final version will released.

Share your experience
=

Let us know of any bugs, suggestions, gripes, kudos, etc. you may
have.


Enjoy!

Hello,

Looks good. All tests pass here on Python 2.6-3.3, 32&64 bit, numpy 
1.7.1, VML/MKL 11.0.3, Windows 8. PyTables 2.4 also tests OK against the rc.

Two small issues:

1) numexpr-2.1-rc1.tar.gz is missing the file missing_posix_functions.hpp

2) The latest version of MKL requires the following change (see 
):

Thank you,

Okay, and that is backwards compatible with older versions of MKL too?

Thanks,

probably it is a little bit late now but it would be nice if you could 
consider to include the patches (patch 0002 and 0003) used in debian [1].

Patch 0001 can probably be avoided by adding setup.cfg to the 
MANIFEST.in file.


thanks in advance

check it out and tell me how it goes.

It seems to be all OK for me and with the patch provided by Anthiny now 
PyTables is 100% compatible with numexpr 2.1rc3.

Ubuntu users can find packages for numexpr 2.1rc3 (both for python 2 and 
pyhton 3) at [1].
