Hi Thomas,
thanks for your suggestion. Also thanks for the PR number. I've tried
with quick way (build.mk) and benchmarking ghc while compiling ghc-cabal
manually and here are the results:
-j1: 45s
-j2: 28s
-j3: 26s
-j4: 24s
-j5: 24s
-j6: 25s
-j6 -A32m: 23s
-j6 -A64m: 21s
-j6 -A128m: 23s

Hi Karel,
could you try adding `-j8` to `SRC_HC_OPTS` for the build flavor you're
using in `mk/build.mk`, and running `gmake -j8` instead of `gmake -j64`. A
graph like the one you attached will likely look even worse, but the
walltime of your build should hopefully be improved.
The build system s
hing over because it is manifestly better.
Andrey can give a status report.

Hi Andrey,
great to hear that you will find some time for Shaking ghc in the near
future and even that you aim to commit first version around April. This
is just in a month and half time. Great! I'll see what it will brings
us, certainly will test it's paralellization capability and will repo

It's certainly agreed to give it a go, and implementation work is

we'll switch. I certainly hope to get full par

Folks,

parallelism of the GHC build recently somewhere but I cann't find it
now. Sorry, for that since otherwise I would use this thread if it was
on this mailing list.
Anyway, while working on SPARC NCG I'm using T2000
