NVIDIA’s next generation GPU architecture has a lot for HPC to love

Yesterday, NVIDIA presented its next-generation GPU architecture, called "Fermi": http://insidehpc.com/2009/09/30/nvidia-next-generation-gpu-fermi-targets-hpc-supercomputing/

In addition to more raw computing power, Fermi brings advances that make it even more interesting for general-purpose computations than the current NVIDIA GPUs. In particular, it seems to support function pointers —at least they claim support for virtual functions— and improved support for double-precision floating-point numbers as well as coarse-grained MIMD support in the form of "concurrent kernel execution".

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.

Tim Sweeney's SIGGRAPH 2009 talk.

http://graphics.cs.williams.edu/archive/SweeneyHPG2009/TimHPG2009.pdf

Tim Sweeney shares his vision of the future of high-end computer graphics and games programming.  Functional programming and data parallelism play an important role.
