Convergence verification of the Collatz problem

The convergence of all numbers below 320 × 260 (≈ 268.32) has been verified. The work unit is 240 numbers. On modern GPUs, verification of one work unit takes 15 seconds on average. All source codes are available on this GitHub repository.

Progress towards verifying all numbers below 321 × 260

Lowest incomplete: 11.6920 % (work unit 335666919 × 240, all work units below are verified)
Lowest unassigned: 11.6922 % (work unit 335666922 × 240, all work units below are assigned or even verified)
