Hey @miran, thanks. I'll look at your code when I get some time today.
It would be really helpful if people could run the code on different (Intel
cpus, AMD, ARM, etc) platforms with different number of threads, cache size,
etc, and if possible a|b it against `primesieve` on their systems, and post
results. I'm going to try and see if I can get (expert) programmers in other
language communities (C++, Crystal, D, Rust, etc) to do it in them and compare
the results. I initially just want to see what their coded versions looks like
(idiomatically), or even if possible (can they do parallel programming, gc,
etc).
Below are updated times for the current version, produced on my System 76
laptop, Intel I7 6700HQ cpu, 2.6-3.5 GHz clock, with 8 threads, and 16GB of
memory. I'm really interested to see how it performs under different threading
systems.
