The uvector package

[Tags: bsd3, library]

Fast unboxed arrays with a flexible interface. The library is built of fusible combinators, as described in the paper /Stream Fusion: From Lists to Streams to Nothing at All/.

For best results, compile with your user programs with -O2 -fvia-C -optc-O3.

Readme for uvector-

The uvector library is a polished up version of the basic flat, unlifted
arrays from the Data Parallel Haskell project. These arrays use
aggressive fusion optimisations, low level unboxed representations, and
a list-like interface, to provide convenient access to fast arrays in
pure Haskell.

As this is all about speed, the library is only available for GHC. 


When to fuse: don't duplicate work.
