I tried the run your code but the compiler doesn't see the euler libraries. eulerprimes.nim(24, 6) Error: cannot open 'lib_euler_math'
How do I get all the libraries to get it to run? I'd be interested in benchmark times. Can you post your hardware specs and the times for counting the primes <= N, for for N = 10^9, 10^10, and 10^11? I don't know if you've seen my sequential SSoZ code, but I'd be interested in how they compare. I'm still learning Nim, and don't know the correct way to implement a parallel version yet, which if done correctly will be much faster. Studying your code I've already learned some Nim stuff I didn't know.
