#11054: GHC on Windows could not use more than 64 logical processors -------------------------------------+------------------------------------- Reporter: varosi | Owner: Phyx- Type: feature request | Status: patch Priority: normal | Milestone: Component: Runtime System | Version: 7.10.2 Resolution: | Keywords: Operating System: Windows | Architecture: x86_64 Type of failure: Runtime | (amd64) performance bug | Test Case: Blocked By: | Blocking: Related Tickets: #12602 | Differential Rev(s): Phab:D2533 Wiki Page: | -------------------------------------+------------------------------------- Comment (by Phyx-): And also, I assume you already compiled your program with `-threaded` ? About the autodetect, yes it should be, but I don't think it's always wanted. Which is probably why they made it an opt-in feature. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11054#comment:25 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
