From quick overview seems like speed up is achieved because there is comparison of 4 local processes, versus 16 processes, since it is only single gather operation does not seem like latency would make much of difference.

I wonder what performance would look like on 5 years old 16 core CPU from ebay for like $20, compared to py cluster.

I assumed it was the M1. (It's an Intel MacBook.)

I tried FindingPrimesMulti.py on a 3970x:

  Find all primes up to: 10000 using 256 processes.
  Time elasped: 0.51 seconds
  Number of primes found 1229

  Find all primes up to: 100000 using 256 processes.
  Time elasped: 36.71 seconds
  Number of primes found 9592

  Find all primes up to: 200000 using 256 processes.
  Time elasped: 149.55 seconds
  Number of primes found 17984

EDIT: ran it again:

  Find all primes up to: 200000 using 256 processes.
  Time elasped: 145.76 seconds
  Number of primes found 17984

this is with a fixed multiprocessing script ?
