enable -threaded so that number of cpus are detected correctly #242

Closed devgrok closed 5 years ago

devgrok commented 5 years ago

From builds done on GHC 8.0.2 on Centos6 + OSX without threaded enabled getDefaultWorkers returns 1. When enabling it, it detects 4 physical cores on my mac (as opposed to 8 logical) and correctly passes it down to cabal via cabal install -j4 etc.

I'm also guessing that the line in mafia.hs has no affect without this turned on.

setNumCapabilities nprocs

-rtsopts isn't probably needed but I just mimicked how mead configured it. (typo in branch name - meant to be topic/enable-threaded)
