synopsis:               An embedded language for accelerated array processing

description:
  @Data.Array.Accelerate@ defines an embedded array language for computations
  for high-performance computing in Haskell. Computations on multi-dimensional,
  regular arrays are expressed in the form of parameterised collective
  operations, such as maps, reductions, and permutations. These computations may
  then be online compiled and executed on a range of architectures.
  .
  [/A simple example/]
  .
  As a simple example, consider the computation of a dot product of two vectors
  of floating point numbers:
  .
  > dotp :: Acc (Vector Float) -> Acc (Vector Float) -> Acc (Scalar Float)
  > dotp xs ys = fold (+) 0 (zipWith (*) xs ys)
  .
  Except for the type, this code is almost the same as the corresponding Haskell
  code on lists of floats. The types indicate that the computation may be
  online-compiled for performance - for example, using
  @Data.Array.Accelerate.LLVM.PTX@ it may be on-the-fly off-loaded to the GPU.
  .
  See the "Data.Array.Accelerate" module for further information.
  .

  [/Examples and documentation/]
  .
  Haddock documentation is included in the package
  .
  The @accelerate-examples@ package demonstrates a range of computational
  kernels and several complete applications, including:
  .
    * An implementation of the Canny edge detection algorithm
  .
    * Interactive Mandelbrot and Julia set generators
  .
    * A particle-based simulation of stable fluid flows
  .
    * An /n/-body simulation of gravitational attraction between solid particles
  .
    * An implementation of the PageRank algorithm
  .
    * A simple interactive ray tracer
  .

  .
    * A \"password recovery\" tool, for dictionary lookup of MD5 hashes
  .
  @lulesh-accelerate@ is an implementation of the Livermore Unstructured
  Lagrangian Explicit Shock Hydrodynamics (LULESH) mini-app. LULESH represents a
  typical hydrodynamics code such as ALE3D, but is highly simplified and
  hard-coded to solve the Sedov blast problem on an unstructured hexahedron
  mesh.

flag ekg
  default:              False
  description:
    Enable hooks for monitoring the running application using EKG. Implies
    @debug@ mode. In order to view the metrics, your application will need to
    call @Data.Array.Accelerate.Debug.beginMonitoring@ before running any
    Accelerate computations. This will launch the server on the local machine at
    port 8000.
    .
    Alternatively, if you wish to configure the EKG monitoring server you can
    initialise it like so:
    .
    > import Data.Array.Accelerate.Debug
    >
    > import System.Metrics
    > import System.Remote.Monitoring
    >
    > main :: IO ()
    > main = do
    >   store  <- initAccMetrics
    >   registerGcMetrics store      -- optional
    >
    >   server <- forkServerWith store "localhost" 8000
    >
    >   ...
    .
    Note that, as with any program utilising EKG, in order to collect Haskell GC
    statistics, you must either run the program with:
    .
    > +RTS -T -RTS
    .
    or compile it with:
    .
    > -with-rtsopts=-T
    .
