I downloaded the reference NIM implementation and got the latest nim compiler, but I received the following error:
  $ nim c --cc:gcc --d:release --threads:on twinprimes_ssoz.nim
twinprimes_ssoz.nim(74, 11) Error: attempting to call undeclared routine: 'sort'

For a person not familiar with nim, what's the fastest way to fix that?

import algorithm

thats all but then it spits out

lib/nim/pure/algorithm.nim(144, 11) Error: interpretation requires too many iterations

My mistake. I updated the file and forgot to include the 'import algorithm' directive. The file is now fixed to include it. Download the corrected version or patch your file accordingly.

As stated in the file intro **YOU MUST DO THIS** to get it to compile with current Nim (they were supposed to fix this in this version 0.19.0 but didn't).

 To compile for nim versions <= 0.19.0 do following:
 1) in file: ~/nim-0.19.0/compiler/vmdef.nim
2) set variable: MaxLoopIterations* = 1_000_000_000 (1 Billion or >)
 3) then rebuild sysem: ./koch boot -d:release

If you are using 'choosenim' to install Nim (highly advisable) the full path is:

 ~/.choosenim/toolchains/nim-0.19.0/compiler/vmdef.nim

I'll post performance results from my laptop to give reference times to compare against.
