Hi all,
I've merged the new parallel I/O manager that Andreas Voellmy and Kazu Yamamoto have been working on. The new parallel I/O manager scales much better than the current one*: the number of requests per second scales almost linearly up to 32 cores I believe. Perhaps Andreas could post the numbers.
Just after Johan's merge, I could build GHC on Mac. But after executing ./sync-all -r git://github.com/ghc --testsuite pull today, I cannot build GHC on Mac: ---- ghc-stage1: could not execute: /usr/bin/gcc make[1]: *** [libraries/template-haskell/dist-install/build/Language/Haskell/TH/Syntax.o] Error 1 make[1]: *** Waiting for unfinished jobs.... make: *** [all] Error 2 ---- I would like to know whether or not this failure is due to our patches. Since building GHC with our patches were unstable on Mac, we made a workaround. Andreas and I need to know that this workaround is stable enough: https://github.com/ghc/packages-base/commit/bcf8724642f3cec73587313878047c87... https://github.com/ghc/packages-base/commit/51a8b9bb878247675b6e003fa081f1a2... http://hackage.haskell.org/trac/ghc/ticket/7651 Any information is welcome. Building GHC on FreeBSD is fine. --Kazu
