Futhark.IR.Kernels.Sizes

Description

In the context of this module, a "size" is any kind of tunable (run-time) constant.

Synopsis

Documentation

data SizeClass Source #

The class of some kind of configurable size. Each class may impose constraints on the valid values.

Constructors

SizeThreshold KernelPath (Maybe Int64)

A threshold with an optional default.

SizeGroup 
SizeNumGroups 
SizeTile 
SizeRegTile 
SizeLocalMemory

Likely not useful on its own, but querying the maximum can be handy.

SizeBespoke Name Int64

A bespoke size with a default.

sizeDefault :: SizeClass -> Maybe Int64 Source #

The default value for the size. If Nothing, that means the backend gets to decide.

type KernelPath = [(Name, Bool)] Source #

An indication of which comparisons have been performed to get to this point, as well as the result of each comparison.

newtype Count u e Source #

A wrapper supporting a phantom type for indicating what we are counting.
