Usually a wu takes about 13,000 secs. this one took 60,000. the other two results were around this normal time. Any ideas?

On my old slow windows box I am attached to two projects. It will switch back and forth between the two projects but keep the one not currently running in memory. There is a bug where the one not running still thinks it is building up CPU time. (A quick check shows it is really not consuming cpu cycles.) By the time the workunit is finished, it appears to have taken a very very long time and claims a very very high amount of credit. My guess is that this is what happened here.

Sounds like Win98 must be your OS. For some reason, the seti science pack does not pause well under Win98.

I suspect there might be a BOINC/SETI CPU time problem on Win98. It almost looks like elapsed time is being used instead of processor time. I recently had an application go into a 100% processor loop when it was ending. I didn't notice this until the next day as it had closed all windows. Since the application was running at a higher priority than SETI, SETI didn't get any processor time during the period, however BOINC showed CPU time accumulating. This was on Win98 but SETI is the only BOINC application running on this system so BOINC was not pausing SETI to switch between projects.

BOINC Version 4.13
SETI Version 4.08

I'm quite certain that on Win98 BOINC is using elapsed time, not CPU time. I've reported this, but nobody seems interested.

Yes it is elasped time, but i think it's on the back burner for now.

Win98 only has elapsed time a process has been running available for checking. It is a limitation of the OS (Win95/98/98se/ME) and not the BOINC implementation. To be able to read a process's actual cpu time, you need to change operating systems. Try WinNT/2000/XP, or one of the *nix OS's (Linux, Mac OSX, etc.) if you are that concerned about it.

[EDIT] - Come to think of it, Win9x is a garbage OS, so switching to something newer would definitely be to your advantage anyway.

I have Win XP installed with a dual boot. I prefer to work in Win98 -- I have better tools there.
