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, and since version 1.4, numexpr implements support for multi-threading +computations straight into its internal virtual machine, written in C. This +allows to bypass the GIL in Python, and allows near-optimal parallel +performance in your vector expressions, most specially on CPU-bounded +operations (memory-bounded were already the strong point of Numexpr). + +This requires numpy. diff --git a/development/numexpr/numexpr.SlackBuild b/development/numexpr/numexpr.SlackBuild new file mode 100644 index 0000000000..97187b33bd --- /dev/null +++ b/development/numexpr/numexpr.SlackBuild @@ -0,0 +1,88 @@ +#!/bin/sh + +# Slackware build script for numexpr + +# Copyright 2010 LukenShiro +# All rights reserved. +# +# Redistribution and use of this script, with or without modification, is +# permitted provided that the following conditions are met: +# +# 1.
