While I would guess that your superlinear speedup is due to the large
variance of your single-core case, it is indeed possible to have
superlinear speedup.
Say you have a problem set of size 32MB and an L2 cache of 8MB per
core. If you run the same program on one CPU it won't fit into the
cache,
Nothing particularly lofty; just a realization that other people didn't
really want to engage in the conversation about LGPL, and I ran out of
time to do so myself.
