Dear List,
I am trying to parallelize Karatsuba multiplication with Haskell's
second generation strategies. Although, I am running the code on an
Intel quad-core CPU, I abnormally have a speedup much greater
than 4, around 10, which means a weird parallelization or something
occurs.
I would
Superlinear speedup can occur due to the increased cache size.

How can I calculate the limits of this speedup via the
cache size of my processor?

Hi.
You may need to make sure that the CPU frequency scaling does not do
anything funny. (like only boosting the frequency to the maximum when
the parallel program is running)
