For one year scan you need 7466805 threads on CPU for 100% success.
This is a completely crazy number.

You’d need advanced alien technology.
Do you think they have such powerful processors?

Use Ryzen threadripper with 256 threads per cpu with liquid cooling, very easy:)
Ok, let’s try dream again. Powerfully srv has 2 cpu, 512 threads total, every srv has 4 RU units (due to water cooling system) in rack mount tower (I think you understand me, English language is not my key knowledge:)) and you need 14583 srv total. Only 12 srv per rack mount tower. You need at least 1215 rack mount towers. Standard machine zone has 30-40 rack mount towers. And you need 31 machine zones full of powerful servers with 2 threadripper CPU and liquid cooling.
Easy game! Have a luck, man:)
