#12685: getNumProcessors semantics dont match documentation ----------------------------------------+--------------------------------- Reporter: Llgn | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: libraries/base | Version: 8.0.1 Keywords: | Operating System: Linux Architecture: Unknown/Multiple | Type of failure: None/Unknown Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: ----------------------------------------+--------------------------------- Hi, The documentation of getNumProcessors says : "Returns the number of CPUs that the machine has", but it is true only for program compiled with -threaded option. https://hackage.haskell.org/package/base-4.9.0.0/docs/GHC-Conc- Sync.html#v:getNumProcessors I guess the documentation is just misleading. Or is it a bug ? Regards -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12685 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
