    11= Repa (REgular PArallel arrays) = 
    22 
    3 Repa provides high performance, regular, multi-dimensional, shape polymorphic parallel arrays. 
    4 All numeric data is stored unboxed. Functions written with the Repa combinators 
    5 are automatically parallel provided you supply +RTS -Nwhatever on the command 
    6 line when running the program. Repa means "turnip" in Russian. If you don't like turnips then this library probably isn't for you.

    8 == Download == 
    9 Repa is split up into a few packages to help control dependencies. 
    10  
    11  * [http://hackage.haskell.org/package/repa repa] 
    12  * [http://hackage.haskell.org/package/repa-bytestring repa-bytestring] 
    13  * [http://hackage.haskell.org/package/repa-io repa-io] 
    14  * [http://hackage.haskell.org/package/repa-algorithms repa-algorithms] 
    15  * [http://hackage.haskell.org/package/repa-examples repa-examples] 
    16  
    17 If you want the lot then just install the examples, and this will pull down the rest. 
    18 {{{ 
    19 cabal install repa-examples 
    20 }}} 
    21  
    22 == Report a bug == 
    23 If you have a bug or feature request, please add a [http://trac.haskell.org/repa/newticket new ticket].[[br]] 
    24 Note that for spam prevention you must first [http://trac.haskell.org/repa/register register] (takes 10 sec) before you can add a ticket. 
    25  
    26 You can also send email to `repa@ouroborus.net` 
    27  
    28 == Examples == 
    29 Here is the output of some of the examples included in the [http://hackage.haskell.org/package/repa-examples repa-examples] package: 
    30  
    31  || fft2d-highpass || Laplace || 
    32  || [[Image(WikiStart:lena-high2-thumb.jpg)]] || [[Image(WikiStart:pls-400x400-out-thumb.jpg)]] || 
    33  || [wiki:Examples/Fft2dHighpass more info] || [wiki:Examples/Laplace more info] ||  
    34  
    35 == Demo == 
    36 There is also an OSX demo that does edge detection on a video stream: 
    37   
    38  || [[Image(WikiStart:beholder-thumb.jpg)]] || 
    39  || video: [http://code.ouroborus.net/beholder/video/Edge480.mov low(10MB)]  [http://code.ouroborus.net/beholder/video/Edge720.mov high(40MB)] ||  
    40  
    41  * The [http://code.ouroborus.net/beholder/beholder-head/ source] should compile with XCode 3.2.1, GHC 7.0.3 and Repa 2.0.0, but you need to update and run the CONFIGURE.sh script to point it to your GHC install.  
    42  * There are also prebuilt OSX i386 versions for [http://code.ouroborus.net/beholder/distro/beholder-N2.tgz two] [http://code.ouroborus.net/beholder/distro/beholder-N4.tgz four] and [http://code.ouroborus.net/beholder/distro/beholder-N6.tgz six] threads. These just have the corresponding +RTS -N# option baked in, you can set it in the main.m module. Some day I will make it so you can select this from the GUI. 
    43  * You can also run the edge detector over a single uncompressed .bmp file using the repa-canny program from the [http://hackage.haskell.org/package/repa-examples repa-examples] package.
