Hi Geoff, Thanks for the update. I found this https://ghc.haskell.org/trac/ghc/blog/weekly20141020

From what you say this has been superseded? Also seems that this page https://ghc.haskell.org/trac/ghc/wiki/SIMD <https://ghc.haskell.org/trac/ghc/wiki/SIMD> should be updated and if I knew what it should say I would volunteer to update it. A bit of background on why I am asking these questions: I am working on a Monte Carlo simulation and performance is a key issue. We are using parallelisation to good effect (after some interesting issues with thread affinity https://ghc.haskell.org/trac/ghc/ticket/10229 <https://ghc.haskell.org/trac/ghc/ticket/10229>) but I am trying to understand what other options might be available to speed things up.
