I’ve been building HelixSeed, a local/offline Minecraft seed scanner focused on extremely high-throughput structure searches.
Instead of running strict validation on every seed immediately, HelixSeed uses a staged pipeline:
1. CUDA placement filtering
Fast GPU prefiltering rejects impossible placement candidates at massive scale.
2. Native strict validation
CPU-side validation checks actual structure generation logic using cubiomes-derived code.
3. Optional post-filters
Biome, loot, sculpt, or Java validation layers can run after strict verification.
Current local benchmark results on my system:
~23B seeds/sec — GPU placement filtering
~3B seeds/sec — native strict validation
Hardware:
Intel Core i5-13400F
NVIDIA GeForce RTX 5060 Ti
The main design goal is keeping placement, survivor, strict, and verified rates separate instead of collapsing everything into one misleading number.
Mixed mode runs GPU placement and CPU strict validation in parallel with a bounded survivor queue, so the GPU can keep scanning while CPU workers verify candidates.
Placement results are fast candidates. Strict results are verified for the selected query.
