I quit boinc from task manager because everytime I quit it from the tray of boinc,what i quitted was just boinc,some projects in boinc still runs(can be seen in task manager),like rosetta,which means I cant really stop the program,it's still occuping resources.Now,I got some new problems,I cant stop the rosetta anymore.when I click stop,it does stop,but next time i want to resume,rosetta start from zero percent again,not from where I stopped it,all the previous works are gone.why? this problem only occur to rosetta,seti and other projects are normal.

Rosetta only checkpoints at certain points and resumes from the last checkpoint when it restarts.

If you kill boinc then it will take a while for rosetta to end. If you exit boinc then rosetta will end immediately. are you running boinc as a service?

I quit Boinc often by using the Task Manager, and I don't have any Problems with it.In Fact you get errors by killing the Process or the Task..try out stopping the boinc-SERVICE in your task manager (its Dienste in german).

If running as a service, then stopping the service is fine. Killing the boinc exe isn't recommended and killing the rosetta exe is probably going to cause the task to error out.

Godfather, there have been some issues lately where the BOINC Manager doesn't seem to be in control of the tasks the way it should be. The manager has told the task to suspend and it does not respond. The result is that you can end up with more tasks then you have CPUs that are running at the same time. And if your suspend on idle or switch to another project's tasks, the tasks that were running at the time don't seem to suspend properly.

Which BOINC version are you using? And which operating system on your machine?

From looking at your tasks page, it looks like all of your machines are Windows XP and BOINC 6.2.19.

Hopefully the cause of the tasks continuing to run after they've been told to suspend will be resolved soon.

Please review the details in this thread. Your machine is requesting zero seconds of work, and receiving zero seconds of work. From looking at your host, you already have one task ready to work on. BOINC will get more when it needs them.

My computer is 1.90 GHz, dual core, with 2 GB of memory. I suspect that your 512 MB of memory is not enough to run certain BOINC projects well; I had problems when my machine had only 1 GB of memory.

The delay between when a task finishes and credit for it is awarded is often less than one day.

Can you afford more memory, and can your machine make use of more? The limit mine can handle is 2 GB, which I have now, or I'd consider going up to the 4 GB limit that 32-bit Windows Vista can handle.

If you can get up to even 1 GB per core, your machine should return results a little faster than mine, although perhaps only half as often if it has only one core.

A WU is a workunit - a piece of work for your computer to do.

I was unable to follow the progress of workunits well until I clicked on the right and left edges of the workunits list screen, and dragged then outward so I could see which workunits were currently in progress.

Clicking the Update button seldom does much unless you have at least one workunit completed and ready to upload.

Your message "waiting to be managed,requested by user" did not translate very well. Which area of BOINC Manager did you see that message on? Projects tab? Messages area?

BOINC will take care of sending back the results when they are completed. It is a two step process. First step is send back the results file. Second step is to update to the project and confirm the file was received. Sometimes it waits a while before doing the second step. This helps accomplish more steps with a single scheduler request, and so reduces the load on the server over time.
