Futhark.IR.GPU.Sizes

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

Documentation

data SizeClass

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.

SizeThreadBlock

SizeGrid

The number of thread blocks.

SizeTile

SizeRegTile

SizeSharedMemory

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

SizeBespoke Name Int64

A bespoke size with a default.

SizeRegisters

Amount of registers available per threadblock. Mostly meaningful for querying the maximum.

SizeCache

Amount of L2 cache memory, in bytes. Mostly meaningful for querying the maximum.
