Convergence verification of the Collatz problem

The convergence of all numbers below 459 × 260 (≈ 268.84) 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 460 × 260

Lowest incomplete: 99.3605 % (work unit 482338254 × 240, all work units below are verified)
Lowest unassigned: 99.4890 % (work unit 482339602 × 240, all work units below are assigned or even verified)
