Default ECM projects @ Nvidia GPUs

Howdy.

I'd like to share some current projects on factoring using ECM method on GPU.
First, there is ECDLP solver, written by Mr. Haandi in September 2009.It's made for Windows, has some python scripts, but it's quite limited.Here it is.

Second, there is a project by Chen-Mou Cheng.It's made for Linux, limited to stage 1 of ECM method and has a special GT200 edition.Grab it here

Does EECM still have a hardwired limit to small numbers (i.e. much less than Cunningham size)? It was developed as a testbed for research into cofactorization for relations from NFS sieving, and that really only needs to factor < 200-bit numbers...
