I don't know about the rest of you, but since:

1) I can't spend credits
2) I can't eat credits
3) I can't barter credits

... the only thing I find credits useful for is comparing different computers/users/processors within the same project. They're useful for deciding which computer is faster. They're useful for deciding how much faster a GPU is than a CPU. They're useful for showing who is contributing a lot to a project.

But they're utterly useless for comparing project A to project B.

I don't decide which projects to participate in based on credits. This isn't a video game, despite having been able to use game consoles as massive number crunchers. It's an opportunity for me to do some good in this world by maybe, just maybe, helping someone solve an important science problem.

Should I participate in a project that might help cure cancer at 20c/hr or one the does nothing useful at all at 100c/hr? For me, the answer is obviously the 20c/hr project, because of the basic reason I'm doing this.

Now, I do realize that the competitive aspect of accumulating credits and moving up on the leader boards is very alluring. I'm not immune to that. I know that this aspect entices LOTS of people to keep donating their resources to worthwhile projects. But I think we should all step back every now and then to remind ourselves why we're doing this in the first place. If you're here to help with the science, do you want the administrators spending their time improving the applications, or trying (continuously!!!) to defend their credit formula vs. the 100 other projects out there?

As for the question about "Where are the tangible rewards?" -- the answer is in the results produced by the cosmology project, and other projects. Whether it's increasing our understanding of the universe, helping to cure disease, proving a mathematical theorem, or finding ET (yeah, I know), the reward is in trying to make the world just a little bit of a better place.

If you have the persistent problem, you may want to try to reset the project, as that will reset the public key in your client_state.xml file, forcing it to be downloaded again upon the next contact.


I've reset the project, but I still get the same error. I'll try detaching and re-attaching.

Edit:

Detaching and re-attaching still produces the same checksum error.

System is Vista 32 bit SP1.

Chris, please read the rest of this thread, instead of just posting in it. The answer has been given by Anshul a couple of posts prior to your post, here.


He may have been referring to the fact that we jusr now started getting those errors again, a day after it was posted that work flow was stopped until the problem could be corrected. Anshul's post, which you refer to, says:

We will first fix this checksum/signature error - which is most likely due to an incorrect "camb" version file transfer from our backup drive and THEN create more WUs.


We've got new work units, and the problem is not fixed, and that sounds like information you guys might potentially be interested in. I suspect that's why he was posting.

And if he wasn't, then I am. :) I got two of those a few hours ago. If the work flow was restarted thinking this problem was fixed, then this is a polite notification that it is still broken. The two that I received were not re-sends that followed no-response timeouts; both were initially sent out on 7-Apr.

Hope this is helpful.
Mike

Yup, always a good thing to have all the critical equipment on UPS. In my case, that's 4 desktop computers, the DVR, and the XBOX. Only the critical stuff! Oh, and the VCR, simply because I hate resetting the time after a power glitch!

Seriously, though, don't forget to put the network gear on UPS too. They don't draw a whole lot of extra power, and being able to talk to the servers when there's a problem could be critical. Also, if you're replicating the database and/or using any kind of NAS or remote mount points, having the routers and switches on UPS will save you some grief. Maybe a lot of grief.

(Yes, I really do have a lot of the entertainment stuff on UPS -- using obsolete older UPSs that were replaced with larger units over the years.)

Many users (nearly, but not quite, all -- I did find a single computer (41989) that was not getting this error) are erroring out on every work unit while trying to download the windows .exe file. It appears to be failing the signature check:

I'm getting the same error continuously, and it looks like everyone else downloading these work units is also getting this error. According to the log, it's a signature error on the executable:
