It has been a luke warm re-start to GFN sieving. This sieve will support 3 new N's in the GFN prime search (1048576, 2097152, 4194304). If you have Windows 64 bit and would like to put it to good use in a specialized sieve (one of which might eventually produce the world's largest prime), then please review these instructions. This manual sieve is located in the Project Staging Area. It's a simple and straight forward process. For more details, please see this post.
