First, why doesn't anything else trigger this, even when I rev up all my cores with processes running an empty loop....
I don't know, but regardless of what ghc does or doesn't do, your computer shouldn't just reboot itself. Try looking elsewhere for the cause of this problem, or workaround it by using `cabal build -jn`, where `n` is smaller than the number of cores you have.
and second, why does "cabal install" use 1 core, while "cabal build" uses many (by default).
For me multiple cores are only used with either `cabal build -j` or `cabal install -j`, or when I set the jobs field in .cabal/cabal.config. If you still get different results, please open an issue with [https://github.com/haskell/cabal/issues cabal]. ghc by default doesn't use multiple cores. I'm closing this bug, as we won't make any progress on it, and there is a workaround. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10159#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
