accelerate: An embedded language for accelerated array processing

[ accelerate, bsd3, compilers-interpreters, concurrency, data, library, parallelism ] [ Propose Tags ] [ Report a vulnerability ]

This library defines an embedded language for regular, multi-dimensional array computations with multiple backends to facilitate high-performance implementations. Currently, there are two backends: (1) an interpreter that serves as a reference implementation of the intended semantics of the language and (2) a CUDA backend generating code for CUDA-capable NVIDIA GPUs.

To use the CUDA backend, you need to have CUDA version 3.x installed. The CUDA backend currently doesn't support Char and Bool arrays.

An experimental OpenCL backend is available at https://github.com/HIPERFIT/accelerate-opencl and an experimental multicore CPU backend building on the Repa array library is available at https://github.com/blambo/accelerate-repa.

Known bugs: https://github.com/AccelerateHS/accelerate/issues

  • New in 0.12.1.0: CUDA backend support for Char and Bool; bug fixes

  • New in 0.12.0.0: Full sharing recovery in scalar expressions and array computations. Two new example applications in package accelerate-examples: Real-time Canny edge detection and fluid flow simulator (both including a graphical frontend). Bug fixes.

  • New in 0.11.0.0: New functions zip3, zip4, unzip3, unzip4, fill, enumFromN, enumFromStepN, tail, init, drop, take, slit, gather, gatherIf, scatter, scatterIf, and shapeSize. New simplified AST (in package accelerate-backend-kit) for backend writers who want to avoid the complexities of the type-safe AST.

  • New in 0.10.0.0: Complete sharing recovery for scalar expressions (but currently disabled by default). Also bug fixes in array sharing recovery and a few new convenience functions.

  • New in 0.9.0.0: Streaming, precompilation, Repa-style indices, stencils, more scans, rank-polymorphic fold, generate, block I/O & many bug fixes

  • New in 0.8.1.0: Bug fixes and some performance tweaks

  • New in 0.8.0.0: replicate, slice and foldSeg supported in the CUDA backend; frontend and interpreter support for stencil; bug fixes

  • New in 0.7.1.0: the CUDA backend and a number of scalar functions
