Last night I started a new GFN WR and it promptly reported that the remaining time would be 312 hours. That is not unusual. This morning the remaining time was reported to be 141+ hours Tonight the remaining time was reported to be 131+ hours. All of this on identity #1 on Win 7.

I switched to identity #2 in Win 7 and started Boinc. It reported 307 hours
remaining.

Now approx 2 hours later I switched back to Identity #1 and Boinc is reporting 302+ hours remaining.

What gives?

Does the wu start over when the identity changes?

What exactly do you mean by "identity changing"?

If you're doing something that causes the BOINC server to think your computer is a different computer, that's likely going to cause problems. Those problems likely include abandonment (complete loss) of existing tasks on the computer.

Supposedly there's a safe way to run multiple instances of BOINC on a single computer, but I've never tried it and can't provide any guidance for that.

This is definitely not a case of multiple instances of Boinc on the same computer. As I watch the time remaining estimate I think it is either the inability of Boinc to make anywhere near a correct time remaining OR it is a case of the wu backing up to the last point where it can start again. In wus other than GFR I noticed that when work is suspended and then restarted the remaining time will back up a few minutes or so but will quickly catch back up. Maybe the GFR wus don't establish a point of reference very often that it can return to and a whole series has to begin over.
I am leaning toward Boinc as the problem.
At the same time it would be interesting know how the wus know where to restart after a suspension.

Having multiple identities is a function of Windows and not Boinc. It allows different users to share the same computer and programs but remain private from each other. Within limits. For me I have a personal identity and also a business identity for the business my wife and I have. They run on the same machine with email, browsers and some programs shared and some not. When I switch from my personal identity to the business identity I can also run Boinc and the wus that were running on the personal identity will be running on the business identity. Boinc is unaware that I changed identity.
I started a new GFN on 4/2 and Boinc reported that it would finish in 162 hours. Since then the estimated time has gone up and down with the estimate at 1 time being over 400 hours. This morning it reports 182 hours.

Boinc estimating run times is like attempting to estimate the time the fox chasing a rabbit will finally catch it.

I think I run Boinc as an administrator but when I download the latest version I will make sure.
