Sorry, It was defined in the last one:
https://gist.github.com/hugosenari/dbc33d833593e3b21eb83299295580b1#methodology

We run 5 operations in 3 threads to make sure we have the following scenarios

  • OP: Now-EPOCH
  • T0E0: First element in the first thread after EPOCH, initial scenario
  • T0E1: Second element in the first thread after EPOCH, serial scenario
  • T1E0: First element in the second thread after EPOCH, parallel scenario
  • T1E1: Second element in the second thread after EPOCH, parallel serial scenario
  • T2E0: First element in the third thread after EPOCH, odd parallel scenario
echo [
  "OP",
  "T0E0",
  "T0E1",
  "T1E0",
  "T1E1",
  "T2E0",
  "T0E1-T0E0",
  "T1E0-T0E1",
].join(sep)
var ops = [getMonoTime(), getMonoTime(), getMonoTime(), getMonoTime(), getMonoTime()]
for i in 0..runs:
  let bigbang = getMonoTime()
  let epoch   = getMonoTime()
  parMap ops, 2, now
  echo [
    $inNanoseconds(epoch  - bigbang),
    $inNanoseconds(ops[0] - epoch),
    $inNanoseconds(ops[1] - epoch),
    $inNanoseconds(ops[2] - epoch),
    $inNanoseconds(ops[3] - epoch),
    $inNanoseconds(ops[4] - epoch),
    $inNanoseconds(ops[1] - ops[0]),
    $inNanoseconds(ops[3] - ops[1]),
  ].join(sep)

Those number has EPOCH inside parMap (now parApply) to reduce createMaster/waitAll noise

We have that third thread to make sure that second one goes into the same branch of first one here
