The py25-numexpr Portfile 58334 2009-09-26 21:16:02Z blb macports.org $

PortSystem 1.0
PortGroup python25 1.0
Name: py25-numexpr
Version: 1.3.1
Category:-append math
Maintainers: nomaintainer
Description: Multiple-operator array expression evaluator
Long Description: The numexpr package evaluates multiple-operator array expressions many times faster than NumPy can. It accepts the expression as a string, analyzes it, rewrites it more efficiently, and compiles it to faster Python code on the fly. It's the next best thing to writing the expression in C and compiling it with a specialized just-in-time (JIT) compiler, i.e. it does not require a compiler at runtime. Also, numexpr has support for the Intel VML (Vector Math Library) -- integrated in Intel MKL (Math Kernel Library) --, allowing nice speed-ups when computing transcendental functions (like trigonometrical, exponentials...) on top of Intel-compatible platforms. This support also allows to use multiple cores in your computations.

If you haven't already installed Darwin Ports, you can find easy instructions for doing so at the main Darwin Ports page.
Once Darwin Ports has been installed, in a terminal window and while online, type the following and hit return:

%  cd /opt/local/bin/portslocation/dports/py25-numexpr
%  sudo port install py25-numexpr  
Password: 

You will then be prompted for your root password, which you should enter. You may have to wait for a few minutes while the software is retrieved from the network and installed for you. Y ou should see something that looks similar to:

--->  Fetching py25-numexpr
--->  Verifying checksum for py25-numexpr
--->  Extracting py25-numexpr
--->  Configuring py25-numexpr
--->  Building py25-numexpr with target all

--->  Staging py25-numexpr into destroot

--->  Installing py25-numexpr

- Make sure that you do not close the terminal window while Darwin Ports is working. Once the software has been installed, you can find further information about using py25-numexpr with these commands:

%  man py25-numexpr
%  apropos py25-numexpr
%  which py25-numexpr
%  locate py25-numexpr
