#12741: --numa doesn't work even if libnuma is available -------------------------------------+------------------------------------- Reporter: darshan | Owner: darshan Type: bug | Status: new Priority: normal | Milestone: Component: Runtime System | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D2620 Wiki Page: | -------------------------------------+------------------------------------- Comment (by Ben Gamari ): In [changeset:"1050e46b5b1640a475fa2fa67616cda8d31308e2/ghc" 1050e46b/ghc]: {{{ #!CommitTicketReference repository="ghc" revision="1050e46b5b1640a475fa2fa67616cda8d31308e2" rts: configure.ac should populate HAVE_LIBNUMA instead of USE_LIBNUMA Code in rts/ which deals with numa checks for `#if HAVE_LIBNUMA`, however this macro is not populated during `./configure`. https://phabricator.haskell.org/D2329 changed this code last and we instead set `USE_LIBNUMA` which fails to setup numa correctly. Test Plan: From main directory in ghc, ./configure && make clean && make boot && make cd nofib/parallel/queens ../../../inplace/bin/ghc-stage2 Main.hs -rtsopts -threaded ./Main 15 +RTS -N24 -s -A64m --numa This fails before this patch with Main: --numa: OS reports NUMA is not available After the fix, it works as expected. Run the validation script, ./validate (It fails with an error in `compiler/utils/Util.hs` saying `GHC.Stack.CallStack` not found, once I remove this 1 line from this file , the script works) Reviewers: hvr, austin, bgamari, erikd, simonmar Reviewed By: erikd, simonmar Subscribers: mpickering, thomie, erikd, niteria Differential Revision: https://phabricator.haskell.org/D2620 GHC Trac Issues: #12741 }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12741#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
