Re: [Algorithms] General purpose task parallel threading approach

[Sebastian S. <seb...@gm...>]

The cool thing about LRB is that it's what they call "vector complete",
meaning it has all of the machinery (scatter/gather etc.) that any parallel
loop with a static call graph could be turned into a 16 wide vector version
mechanically. This should hopefully allow the compiler to do most of this
work for us if we just mark up the loops we think ought to be data parallel
using some pragma.
