datadata Comp

Computation strategy to use when scheduling work.

Constructors

Seq
Sequential computation
ParOn ![Int]
Schedule workers to run on specific capabilities. Specifying an empty list ParOn [] or using Par will result in utilization of all available capabilities.
ParN !Word16
Specify the number of workers that will be handling all the jobs. Difference from ParOn is that workers can jump between cores. Using ParN 0 will result in using all available capabilities.

patternpattern Par :: Comp

Parallel computation using all available cores. Same as ParOn []

patternpattern Par' :: Comp

Parallel computation using all available cores. Same as ParN 0

valuegetCompWorkers :: MonadIO m => Comp -> m Int

Figure out how many workers will this computation strategy create.

Note - If at any point during program execution global number of capabilities gets changed with setNumCapabilities, it will have no affect on this function, unless it hasn't yet been called with Par or Par' arguments.
