Hello everyone. I have published my optimized versions of VanitySearch (CUDA) with speed boost in case anyone is interested

The "bitcrack" version is specific to the puzzle and allows searching for addresses and prefixes (compressed) within a given range. The speed is about 6900 MKey/s on a 4090 and 8800 MKey/s on 5090.

The second version, on the other hand, performs a standard search for vanity addresses (not just P2PKH compressed) but with the same optimizations in terms of math and CUDA code. Random searches with endomorphisms.

Thanks!

why not multi-gpu?

The "standard" version allows multi GPUs

The "bitcrack" version does not. since the range size is a power of 2 the number of GPUs must be as well in order not to have overlapping keys. It would also be slightly slower because the threads of one GPU have to wait for the threads of the other to finish, which is a problem if the 2 GPUs do not have the same speed.

It was a choice to keep things simpler and a little more efficient

Cuda 8 version available?

Nope sorry:(
