Second beta release for the CUDA backend of Accelerate

The second beta release of Data.Array.Accelerate (version 0.8.0.0) includes support for all array operations in the CUDA backend — except for a new stencil operation that is new in this release and currently only supported by the interpreter.  The CUDA backend requires CUDA 3.x and has been tested on consumer-grade GeForce cards, TESLA high-performance GPUs, and the new Fermi cards.

If you are interested in general-purpose GPU programming in Haskell, give this release a spin — it is available on Hackage.  While it is far from perfect, it should already prove useful for a considerable range of applications.  Together with the other Accelerate developers, I would be very interested to hear what works for you and what doesn't.  We are also interested in suggestions for the future development of the library.  Accelerate has a mailing list and a bug tracker on which we also accept feature requests.

First release of the CUDA backend for Accelerate

During the first Australian Haskell Hackathon, AusHac2010, we finally managed to complete the integration of the CUDA backend, written by Sean Lee and Trevor McDonell, into the array EDSL Accelerate.  It still doesn't cover the complete functionality of the current version of the Accelerate EDSL, but already allows for interesting GPU computations.  The package source (version 0.7.1.0) can be obtained from Hackage as usual.  There is now also a bug tracker.

Don Stewart's talk on Domain Specific Languages and Haskell

Don argues in favour of domain-specific languages for high-performance computing. Not surprisingly, he suggests that Haskell is well suited as a host for realising such domain-specific languages as embedded languages: http://donsbot.wordpress.com/2009/10/16/lacss-2009-domain-specific-languages-and-haskell/

Haskell Arrays, Accelerated

The slides from my talk Haskell Arrays, Accelerated (Using GPUs) at the Haskell Implementors’ Workshop (that was co-located with ICFP 2009 in Edinburgh) are now available. The talk introduces a novel framework, based on an embedded domain-specific language of multi-dimensional array computations, targeting GPUs and other acceleration hardware.

Converting typed term representations: from HOAS to de Bruijn.

http://www.cse.unsw.edu.au/~chak/haskell/term-conv/

Given a GADT representation of a typed higher-order term language using higher-order abstract syntax (HOAS), it is more difficult to convert to an alternative GADT representation using de Bruijn indices for bound variables than I at first expected.  Here is a solution using explicit type representations (with Data.Typeable).
