Did it work?

If it wasn't massively more performant than other ways to write that program in C#, then maybe it's just fine for the purposes of "Energy Efficiency across Programming Languages".

What is the relationship between multicore and energy efficiency?

> This is not a fair comparison.

The comparison is energy efficiency not elapsed seconds, yes?



Comparing the energy efficiency of code that's not even doing the same thing is not a useful comparison. If you're running these benchmarks on a server that's always running full throttle then using more cores will use less power because the software finishes faster. If you're running on a laptop the relationship between core usage, elapsed seconds, and power usage is very non-linear.
