[Haskell-cafe] Meaning of fizzled sparks?

[David Banas]

Hi all,

If this code:

  f5Rslts      = map (f5 (n-1) startingMinScore startingMaxScore (otherColor clr) 0) newBoards `using` parList rdeepseq
  totalMoves   = sum $ map snd f5Rslts  -- Attempt at parallelization yielded no perf. improvement.

is yielding a fizzled spark ratio of about 0.3,
does it imply that the sum begins pulling from the list, before the sparks have had a chance to compute the first third of the list elements?

Thanks,
-db
