Currently one Wu is running. And I want to have a second one. CPU-Usage is at 100 percent for my Dual-Core.

The last line would suggest that it doesn't think you'll be able to finish it in time. Do you have a slow graphics card and/or a big cache setting?

I use a 8800GTS512@760/1900/100. Fast enough. So what do you mean with big cache setting?

How big is your work cache setting?

Your work buffer settings as set in preferences. Resource share can also play a part because BOINC Manager may not be correctly distinguishing between GPU resource allocations and CPU allocations.

This is supposed to be one of the fixes in the 6.6.x series, but, it is a work in progress. To this point, I think most of us have settled in on 6.5.0 as being the best compromise ... at least, I have seen no major complaints and it is the version I am using ... You may have to delve into the archive to get this version as it was not one of the recommended versions.

Is the projected run time of your one GPU-WU way off?

No, it takes 6.8 Hours to finish it. While 6 Hours are elapsed to reach 55 %.

Under previous incarnations of BOINC it used to add the cache size (10 days in your case) and check the deadline, before downloading the wu. As GPUgrid has 4 day deadlines that means unless you have a smaller number in the cache setting (say 3 days) it won't think its able to finish in time.

I said "previous incarnation" because they changed the whole work-fetch stuff in 6.6.2 so it may not work that way any more.

I've just installed 6.6.2. Can't get new work at all with this new version:

How to do?

My first thought is to suggest to revert to 6.5.0 which I have had the best luck with ... you should be able to access it thiough the archive link on the DL page.

I have only one instance of 6.6.2 BOINC Manager running and I am not sure that it is requesting for me correctly either. The trouble is that I have at least one additional task in the queue and so it looks like I really need to wait till it is in work or done before I can be sure I am having the problem.

The thing is that the server messages have been changed and I am not at all sure that the change is backward compatible for CUDA projects ... in other words, GPU Grid might not be really set up to respond correctly to 6.6.2 ...

{diit}

If you have no work, you could also try project reset ... but ONLY if you have no work in progress or you will lose that too ...

I just rolled back to 6.4.5. Now I am not in good feel to something else. If it doesn't work, I don't need it.

newer version of the client like 6.6.2 are probably not 100% compatible with the server version of GPUGRID. We will do a project update next week. I hope that it will be smooth for users with older clients.

I'd probably hold off a bit on that. It would seem the server side changes at seti are causing too much work fetch, even when set to NNW in the client. It does this to both new and old BOINC clients (reports of 5.10.45, 6.2.19 and 6.6.2).

Now it's running good. I removed everything via deinstall and manual deletion of directories. Before I tried the 6.5.0, where I had to pause the other projects to getting work for GPU-Grid. The Boinc Beta-Versions are the biggest zone of error, obviously. Since 2 month of manual updating, which is very annoying, the project runs fine on my 2 pc's, now. If I had more pc's or faster systems, it would be quite safe to become insane in this time.
