Plus choosing a problem that has parallelism in the first place ...

Note also that use of "just" - whenever I see that word it raises a big red
flag. We use it a lot talking about software, usually as a way of dismissing
something that's a huge obstacle out in the real world. Try it for hardware and
see what happens "why doesn't Intel just increase clock speed 10% ?"

Parallel programming isn't "too hard". Parallel programming that scales well
with number of threads when running on hardware with limited memory bandwidth and
with SMT threads that actually slow each other down in unpredictable ways by the
sharing of core execution resources and cache space ? Harder.
