ANN: Numexpr 2.6.6

Robert McLeod
 Announcing Numexpr 2.6.6

Hi everyone, 

This is a bug-fix release. Thanks to Mark Dickinson for a fix to the thread 
barrier that occassionally suffered from spurious wakeups on MacOSX.

Project documentation is available at:

Changes from 2.6.5 to 2.6.6

What's Numexpr?

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 has multi-threaded capabilities, as well as support for Intel's
MKL (Math Kernel Library), which allows an extremely fast evaluation
of transcendental functions (sin, cos, tan, exp, log...) while
squeezing the last drop of performance out of your multi-core
processors.  Look here for a some benchmarks of numexpr using MKL:

Its only dependency is NumPy (MKL is optional), so it works well as an
easy-to-deploy, easy-to-use, computational engine for projects that
don't want to adopt other solutions requiring more heavy dependencies.

Where I can find Numexpr?

The project is hosted at GitHub in:

You can get the packages from PyPI as well (but not for RC releases):
