Wait a minute. If he just said that the 3060 achieves around 2300 Mkeys/s, how much does the 4090 achieve? Does it reach 8000 Mkeys/s on the RTX 4090? 8 GK/s ?  In Cyclone GPU ?

Why won't anyone share the fastest GPU code here? Are you hiding the best code for yourselves?  It's all just empty talk and blah blah blah.. Tongue



Because no one is obliged to put their work in the public domain for everyone to see. They spend their time and energy on it.
Because I am doing it right now:) The main target - to be twice faster than KeyhuntCUDA, but it is possible only with PTX ASM. And also if somebody knows an algo of Modular inverse faster that DRS62 - let me know. this is the main goal for me. Or stupidly do all of the code with PTX, that impossible for me

When computing modular inverses in batch, the individual function to calculate the inverse has very little impact on the overall speed. In my version, a "stock" 4090 achieves around 7Gkey/s with some optimizations.

Still, it's crazy to see how in a group like this, 3/4 of the posts go against all common sense and basic rules of statistics. I'm referring to the absurd theories about prefixes and bit permutations.
I agree with you, sequential brute force is the best way for solving puzzles without pubkey. And one question, could you take me a link to your version of Keyhunt cuda?

KtimesG, I need a few time to understand your opinion:) I checked occupancy of my rtx4060 via nSight Computing, and I have seen “register pressure” on SM (33.3% of occupancy) and spill to DRAM. I will do some work for recalculate algos for decreasing pressure.

It's not a version of Keyhunt but of VanitySearch-bitcrack, though I don't think it makes much difference Smiley
