GHC Weekly News - 2015/03/10

Hi *,

It's that time again! Today GHC HQ met on a Tuesday to avoid some scheduling conflicts, and that means it's time to send some news to people.

Just a quick reminder from last week: we're hoping to make our third GHC 7.10.1 release candidate on Friday, March 13th, with the final release on Friday, March 27th.

  • Today, GHC HQ mostly talked about 7.10 bugs; HEAD is steaming along as usual with no impediments, but we've got several critical bugs we plan on landing fixes for this week; see milestone:7.10.1 for more.

But we've also had a little more list activity this week than we did before:

  • Karel Gardas wrote to the list about how to better parallelize the GHC build. For background, he's using a UltraSPARC T1-CPU/T2000 server with 32 hardware threads over 8 cores, where parallelism is a bigger win than raw single-threaded performance. But despite that, the performance is of the parallel GHC build is relatively abysmal - and Karel wants help brainstorming ideas to fix it. https://mail.haskell.org/pipermail/ghc-devs/2015-March/008474.html

Some noteworthy commits that went into ghc.git in the past week include:

Closed tickets the past week include: #7854, #10118, #10119, #3321, #10132, #9987, #10126, #9707, #10142, #10147, #10113, #9524, #10058, #10100, #2991, #10140, and #9122.
