RTS options for SMP parallelism also, i propose to enable +RTS -N by default. Haskell is very popular as multithreaded language, don't fool novices! I don't think we're ready for that yet. The current implementation assumes that it has access to the given number of cores, and performance degrades severely if it doesn't. So for example, using -N2 on a 2-core machine may perform badly unless the machine is otherwise very quiet. I've been working on improving this, but it's quite difficult: using spinlocks and busy-waiting is a lot faster than using sleep/wakeup synchronisation when you really have all the cores, but when you lose a core things go haywire. I've tried the usual spin for a bit and then go to sleep technique, but even that can adversely affect performance when you really do have all the cores, because sometimes we do have to spin for quite a long time. The only proper solution is not to synchronise at all, which is what we're looking at now (CPU-independent GC). You may notice this effect more with 6.12.1 because we turned on the parallel GC for generation 0 by default. This improves performance for parallel programs a lot (see ICFP paper), but also means there are many more all-core synchronisation points, which in turn will really hurt if any of our threads is descheduled by the OS. So right now, on a dual-core I'd recommend using -N2 -qg1 (don't use parallel GC in gen 0), or -N2 -Hlarge. The -gn RTS option has been removed, except that -g1 is still accepted for backwards compatibility. why not ignore whole option for a 6.12.*? Because people might be using -g1?

Re: ANNOUNCE: GHC 6.12.1 Release Candidate 1
This new version of ghc can no longer read ISO-8859 text. Text is cut off after the first non-ascii character (ie. ¢). Is this somewhere documented? What is the recommended way to handle such text?

What's the canonical way to install a version of ghc but not have it be the default? i.e., I'd like to try testing this release candidate but I want to have to call it explicitly; I want 'ghc', 'ghc-pkg' etc. to still be aliases to ghc-6.10.4, instead of being overwritten by the 6.12.1 install. -Brent On Sun, Oct 11, 2009 at 09:41:53PM +0100, Ian Lynagh wrote: Hi all, We are pleased to (finally!) announce the first release candidate for GHC 6.12.1: http://darcs.haskell.org/~ghc/dist/6.12.1rc1/ As well as the source tarball: ghc-6.12.0.20091010-src.tar.bz2 there are installers for Windows (i386) and OS X (i386), and binary distributions for x86_64/Linux and i386/Linux.

ANNOUNCE shows ``version 6.10.1'', and lists the old features. What is the difference of 6.12.1 w.r.to 6.10.4 ? Release notes here, for now: http://www.haskell.org/ghc/dist/current/docs/html/users_guide/release-6-12-1.html In section 1.5.2. Warnings there is a duplication: * There are two new warnings if a monadic result of type other than m () is used in a do block, but its result is not bound. The flags -fwarn-unused-do-bind and -fwarn-wrong-do-bind control these warnings. * There is a new warning if a monadic result of type other than m () is not bound. The flag -fwarn-unused-do-bind controls this warning. Cheers Ben ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users

What I do is keep my default as /usr/bin/ghc, then when I install testing versions I just rm the unversioned ghc scripts that get installed in /usr/local/bin/ (because /usr/local/bin appears on my $PATH first).

When compiling, I get lots of No such file or directory errors. The compilation process continues, but should I be concerned about this?

Re: ANNOUNCE: GHC 6.12.1 Release Candidate 1
Barney Stratford: this one built and installed fine on Mac OS X 10.6 :). Interesting, I thought there were still problems there. I assume that's a 32-bit version. The problems manifest themselves only when you compile a 64-bit GHC. That's incorrect. The 32-bit version is only partially working. GHCi dies with a bus error (after package loading) and various features that need the interpreter/dynamic loading (such as TH and annotations) die under certain circumstances. Disclaimer: I didn't actually test this with 6.12.1RC1, but with 6.13. However, there shouldn't be any difference as I am not aware of any 6.12.1-specific Mac fixes. Manuel PS: I am chasing these bugs, but I don't have a lot of time for that at the moment, they are tricky bugs, and my Mac-fu is still pretty limited. So, if anybody else likes to have a go with gdb and dtrace, please do so. ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
