It attempts to compile modules in parallel by subdividing the work of the upsweep into parts that can be executed concurrently by multiple Haskell threads. In order to enable the parallel upsweep, the user has to pass the -jN flag to GHC, where N is an optional number denoting the number of jobs, or modules, to compile in parallel, like with GNU make. In GHC this just sets the number of capabilities to N. }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/910#comment:54> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
