data SOAC lore Source #

Constructors

Stream SubExp (StreamForm lore) (LambdaT lore) [VName] 
Scatter SubExp (LambdaT lore) [VName] [(SubExp, Int, VName)] 
GenReduce SubExp [GenReduceOp lore] (LambdaT lore) [VName] 
Screma SubExp (ScremaForm lore) [VName]

A combination of scan, reduction, and map. The first BasicOp is the size of the input arrays. The first 'Lambda'/'SubExp' pair is for scan and its neutral elements. The second is for the reduction. The final lambda is for the map part, and finally comes the input arrays.

Fields

identitySOACMapper :: Monad m => SOACMapper lore lore m Source #

A mapper that simply returns the SOAC verbatim.

mapSOACM :: (Applicative m, Monad m) => SOACMapper flore tlore m -> SOAC flore -> m (SOAC tlore) Source #
