Yes, it's an estimated time. BOINC can't possibly know how long the task will take on your computer, not unless it has run multiple instances of the same kind of task, only then will BOINC be able to guess better at how long these usually take.

With the wild variety in hardware out there, it's not possible to send out work with an exact run time length which shows correctly on each different piece of hardware, so all tasks come with an estimate on how many floating point operations per second they're going to use. Depending on the FP strength of your CPU or GPU, this value is then either too low, or too high. And then during the run of the task you will see wild time estimate fluctuations.

It'll take around 10 tasks for BOINC to get the estimate right. And even then, what with the project having different applications (multibeam and astropulse), both with different FP estimates, AND there being a fluctuation between run time length of the various tasks (depends on their angle range)... it may just take a while. As long as you leave BOINC well alone and aren't going to force it to run something else, it'll get there in the end.

cheers, it finished after 85 hrs or so, seems to be running cpu bench marks a fair bit, but comes with the job i guess.

The other thing that is happening for me is that my elapsed time keeps restarting! I've noticed that I was at 18.25.31 hours at 11 pm 2 days ago and now my time is reading 2:45:11. What's that about? No credits have been applied, and it doesn't look like I'm starting a new project. Just treading water on a river taking me nowhere.

With your computers hidden on your account, it makes it difficult to see what's going on. I think there's a good chance that you've started another task (projects are things like SETI@home, Einstein@home, Milkyway@Home, etc) and haven't noticed. There's also a chance that something is causing the task to restart, and without more information, it would be nearly impossible to point you to a correct answer.

Your computer is hidden, so we can't see any results that might have been completed or errored out. Looking at your other projects, you are running a Mac. Seti doesn't support the GPU in your system. (Don't I wish they did, but that belongs to another thread) You also seem to be running more than 1 project at once. Some projects will take priority of your system to utilize their resources for that project. Bonic will shift between projects every few hours based on your preferences listed. Can't say for sure if that is happening with you. As you can see by the above reply regarding time to completion. You will have to run 20? work units before seti gets a good idea on estimates of how long your system takes to complete work units. You might want to suspend all your other projects and only allow seti to run by itself for a while and see if it completes any work units and improves your time to completion. Let us know how it goes.

It definitely wasn't a new project starting, as no credits have been posted to my account.

If Seti doesn't support CPU on my Mac, does it make sense to even participate in this project? Why wouldn't the system reject my offer to participate before starting if my CPU's can't be used?

I am running several projects at once, and some have completed, but the Seti one(s) just never get anywhere. The time to completion has now gone up to 107+ hours, and keeps going up faster than the time elapsed, which only inches up throughout the day and night. It seems I should probably remove this one (there are actually two Seti & projects running.)

What do you suggest?

So Sorry. I've posted all this on the wrong message board. I've clicked on the wrong website on the BOINC screen. It is the QNC Sensor that is doing this crazy thing, not SETI. So sorry for the confusion. Ignore my recent post. Thanks.

It's ok, that explains why I couldn't see your system. Seti supports your CPU, not your GPU (graphic card). Well good luck then with that other project.
