#8594: sysctl name "hw.ncpu" (HW_NCPU) is deprecated in Mac OS X -----------------------------------+------------------------------------ Reporter: kseo | Owner: simonmar Type: task | Status: new Priority: normal | Milestone: Component: Runtime System | Version: 7.6.3 Resolution: | Keywords: Operating System: MacOS X | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -----------------------------------+------------------------------------ Comment (by carter): benchmark suite for which? using the physical cpu count? thats be like using -N2 rather than -N4 (as our default value of -N). In performance sensitive applications, using the physical core count can sometimes be a win because of better cache behavior, but defualting to using the logical cpu count is the right default for general purpose applications. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8594#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
