Armadillo ECDLP Solver v1.4.5 — CRITICAL UPDATE: Cycle-Reset Diversity Fix

Immediate release of v1.4.5 — critical fix for a bug that caused Distinguished Points to stall after ~3.7 hours of computation.

The problem:
When worms reach the cycle limit (8 × 2^25 steps ≈ 268M steps), they need to restart from a new point. v1.4.4 selected only 2 walk table entries (5+5 = 10 bits), producing just 992 unique starting points for 174,080 worms. Result: ~175 worms per point, all replaying the same walk → 97% duplicate DPs. Unique DPs stalled at ~154K overnight.

The fix:

32-bit bitmask to select a subset of all 32 walk table entries → up to 2^32 unique starting points (~4.3 billion)
Per-worm resets counter to guarantee diversity on every subsequent reset
splitmix64 device-side hash for robust seed mixing
Zero performance impact: same 96 registers on sm_120, 0 spills, same speed
Verification:
After deployment, unique DPs immediately resumed growing (155K → 161K within minutes). 26/29 agents already updated automatically.

Download the new version from the dashboard: https://ecdlp.protect.cx/download/ArmadilloSolver.zip

Replace solver_fast.exe and restart your agent. Command line arguments remain unchanged.
Note: Checkpoint format has changed (new worm_t struct). Old checkpoints are incompatible — agents will restart from scratch, but all DPs already collected on the server are valid and preserved.

How did the agents update automatically?

I didn't find any auto-update feature.

They didn't — there's no auto-update feature right now, but something new is under beta testing.
The users of those 26 agents simply downloaded the new build from the server's /download endpoint and restarted their agents manually.
Poor wording on my part, sorry for the confusion!

To update: download as usual the latest ArmadilloSolver.zip from the server, replace your solver_fast.exe, and restart.

Live Stats (as of now):

29 active agents — 25x RTX 5090, 2x RTX 4070 Ti, 1x RTX 3060, 1x RTX 5070 Ti
90.73 G/s combined throughput
254,011 unique DPs collected (440K total submitted)
4.89 × 10¹⁵ iterations computed so far
36.3% progress toward expected collision
0 collisions yet
ETA: ~12 hours to median collision point

Hi cjack,

I'm contributing on this ECDLP Solver, can you kindly include the source code with v1.4.5 version published on the dashboard website.

Thanks for contributing to this "crazy" project! We'll find the collision point!
