I need to uninstall/reinstall BOINC, but I don't want to do so until all existing tasks are complete. I've set the project to "nomorework", and now there are two tasks in "ready to start" status, and none that are running. How can I get those tasks running, so I can empty out my pipeline?

A problem with the BOINC scheduler? Say it isn't so! From my experience, it seems to get dumber the longer it runs. So, you may have to exit BOINC and restart it. They are ATI wu's so only one will run at a time when they finally do start.

Other options are:
1. Collatz will resend lost WUs so if you use the same email and password and the computer name remains the same, it should give the host the same cross project id (I think) and resend any WUs that were lost when it was uninstalled.

2. You could abort the WUs. They would then be sent to someone else.

3. You could backup the boinc data folder prior to uninstalling and then restore it after reinstalling and prior to starting BOINC for the first time.

Thanks for the clue. What I hadn't realized is that ati tasks are distinct from cpu tasks; I'd expected to be able to start them on the cpus. The GPU is crunching away; once they're done, I'll reload BOINC with the options I want, and get started again.

Well, I got BOINC reinstalled, and it seemed to work all right for a while. Now, though, it just sits there. It's not downloading any new tasks. Help?

I keep on getting the message that there are no WU's for ATI

There have been several reports of issues getting ATI work. I have a hunch that fixing the CUDA42 scheduler problem somehow broke something for ATI GPUs. I'm trying to track that down now. Thanks for your patience.

While fixing the CUDA 4.2 issue, I inadvertantly introduced a change to the scheduler which was meant for HD 7xxx GPUs so that they would receive the OpenCL version of the application instead of the Brook+ version which does not work correctly on the newer GPUs. Instead of not sending ATI tasks to HD 7xxx GPUs, it stopped sending any tasks to any ATI GPU. That should be fixed now. If you continue to have issues now, please:
1) enable sched_op_debug in the cc_config.xml and report the output from the event log
2) make sure your computers are not hidden (it saves me a lot of time looking for gigabytes of log files if I know the ID and GPu type, etc. to look for.
