I didn't see, in the release notes (http://www.haskell.org/ghc/docs/7.0.2/html/users_guide/relea...), any mentions of improved inlining or thread scheduling. Do you have a link to that?

Those came with ghc 7.0.1.

Why is GHC doing thread scheduling?

fp• 15 years ago

Haskell (GHC at least) has lightweight user-level threads, similar to Erlang.

(Disclaimer: I've never programmed Haskell or used GHC outside of Xmonad)

I'm pretty sure they use a M:N language-thread to OS-thread system. So they need to decide what thread to put "on" an OS-thread at any given time.

GHC provides a parallel programming model,

* K sparks scheduled over * M lightweight threads scheduled onto * N OS threads over * C hardware cores.

The runtime manages this, and does load balancing.

I'm confused. Their site says GHC 7.01 was released in November 2010. This release is 7.02.

7.0.1 was the release candidate for 7.0.2 (stable).

Sounds like they learned their release numbering skills from the KDE folks.

Yes, the title is confusing. GHC 7.02 is significant because it will be included in the next Haskell Platform release -- GHC 7.01 was only available separately, and was not much installed.

GHC 7.01 was also a time of upheaval in the code base, with an almost total rewrite of the type checker. This was a bit buggy at first, but early experience with 7.01 means that it is much more polished in 7.02.

The full changelist from 7.0.1 is modest and available at http://www.haskell.org/ghc/docs/7.0.2/html/users_guide/relea...

How does this LLVM integration work? Is just a Haskell->LLVM compiler?
