Description

This module implements a Meta-Par Resource for SMP parallelism, suitable as a base for combined execution resources (e.g., Control.Monad.Par.Meta.AccSMP).

Synopsis

Resource creation

mkResource Source

Arguments

:: Int	The number of steal attempts per `WorkSearch` call.
-> Resource

Create an SMP resource for all capabilities.

mkResourceOn Source

Arguments

:: [Int]	Capability list.
-> Int	The number of steal attempts per `WorkSearch` call.
-> Resource

Create an SMP resource for a configurable list of capabilities.

Default implementation

defaultStartup :: Startup Source

Startup for spawning threads on all capabilities, or from a read-able list of capability numbers in the environment variable SMP_CAPS.

defaultWorkSearch :: Int -> WorkSearch Source

WorkSearch for all capabilities.

Customizable implementation

startupForCaps :: [Int] -> Startup Source

Startup for spawning threads only on a particular set of capabilities.

wsForCaps :: [Int] -> Int -> WorkSearch Source

Given a set of capabilities and a number of steals to attempt per capability, return a WorkSearch.
