He're one that seems to have plenty of work:

I have been running it for 9 months with few issues. It has been around for a long time and has over 500 teams with over 9000 people contributing. It appears to be a brute force attack on the SHA hash.

It has windows, linux32 and linux64 clients. The only issue I had was the correction factor on the project starts off **WAY** out of whack. You will be fine if you take the default .25 day work, but if you have your queue set to 2 or more days, the work will expire before you can get to it. So, other than a small start up glitch, I haven't had any major issues, and there seems to be plenty of work.

An update since my last post.

I recently added a few machines to this project just to see how it went. Work has been reasonably stable.

I did find another abnormality. Nothing that would stop inclusion, but something to note.

This project has a linux64 client that is significantly slower than the 32 bit client. Manually editing your config file is supposed to help. AMD processors are noticeably faster than INTEL processors. These two combine in such a way that an AMD BE-2300 running windows 2000 (32 bit) earns more points/day than an Intel quad (q9300 and q6600 both tested) running linux64. That same BE-2300 running windows 2000 (32 bit) also earns more points/day than a faster c2d running windows xp.

So, anyone wanting to run this project, be advised that it strongly favors AMD processors running a 32 bit version of windows.

Aye, been crunching SHA-1 on and off 2 days short of 12 months, apart from the front page updates being virtually non-existent I can't find fault with the project :thumbsup:
