primitive-simd: SIMD data types and functions

This package provides a lifted version of the SIMD data types and instructions from ghc-prim.

The implementation is based on type families to provide a uniform interface to all different vector types. Instances for numeric operations, Prim, Storable and unboxed vector instances are provided.

Although not all processors support 256 or 512-bit vectors this package provides a uniform interface. Vectors which are bigger than supported are modeled by combining smaller vectors. If the same code is compiled on a computer supporting larger vectors the smaller vectors are replaced by larger vectors.

Note: This package needs to be compiled with LLVM as the NCG does not know how to deal with SIMD-instructions. If LLVM is not available, use -f no-vec to disable the use of SIMD instructions. While this will give you no speedup, it will work with plain Haskell (and should even work with GHCJS).

Flags

Manual Flags

Name	Description	Default
no-vec	Disable all vector hardware instructions. Your code will run on all hardware but also be a lot slower.	Disabled
vec256	Enable 256-bit vector hardware instructions. Your code will only run if your CPU supports 256-bit vector instructions.	Disabled
vec512	Enable 512-bit vector hardware instructions. Your code will only run if your CPU supports 512-bit vector instructions.	Disabled

Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info
