I'm not sure what's up with my main computer. Everything used to be running fine, I had my prefs set to connect every 7 days or so and had a big list of work units in my tasks tab.

Seti/BOINC runs almost 100% of the time but my stats say that work is allowed only about 13% of the time. However, with all the times I have checked, I have never see SETI not working on a unit. When I check CPU useage, seti is usually around 90-95%. I have found in Task Manager that it's priority it set to "Low" and every time I try to change it back to "Normal" it stays there for a bit then changes itself back to "Low". And now I only have about 3 work units at a time even thought they are only taking my computer 4-6 hours each to process.

Any ideas out there as to what may be causing this?

Thanks!
Jai

I just noticed that 432000 seconds of new work was requested but I only got 3 work units. I used to get a whole list of them.

Boinc is designed to work at the lowest priority so as to not interfere with your normal use of the computer, but uses up whatever free CPU cycles are available. On most system this is in the range of 90 to 98%.

There are a couple of factor effecting the Boinc run time.
The number of hours the computer is on during the day.
General preferences setting.
Do work while computer is in use? yes/no (Most people can get away with saying yes as Boinc is very good at getting out of the way of other work)
Do work only between the hours of (no restriction) or time settings.

Boinc use the stats information, the connect time and completion time of WU on your system in determining how much work to download.

The new Seti enhanced application takes much longer to crunch a WU as it does a much finer analysis for data so fewer units will be downloaded at a time.

Hello,

that's exactly the problem I'm facing too!

Former WUs need 3 - 4 h and the advanced ones need
just 6 - 7 h. This is not the difference. My requested
work was 10 days, which means 40 - 50 WUs. Now I get
3 - 4 WUs (for 10 days ??) and this state is lasting
now for 1 month. There is something wrong with the
distribution criteria. My computers runs (in former
better times) for 6 days finishing those WUs (40 - 50).
Then I had 1 day off for getting new work. The result
was an rate of 130 - 140 credits/day. Now I've
sloped down to 77 since I've to feed every 2nd day
having 50% offtime (compared to former 6/7 * 100 %).

I hope somebody will find out what has gone wrong.

regards,

Manfred

Nothing has gone wrong. Seti started with Seti Enhanced on the 4th of May and has only been releasing SE results since the 16th of May.

Seti Enhanced results do take a long time. They not only vary in deadline, but also in crunch time. It depends on the Angle Range the result was "shot" at how long it can take. For approximate times, check here.

Thats just it though, my computer is crunching at the same rate, 3-7 hours per work unit but is only downloading 3 at a time even though my prefs are set to only connect every 7 days.

I'm not getting 7 days worth of units, more like 21 hours worth.

Just give it a bit more time. Your Result Duration Correction Factor is now totally confused. It can take some time for that one to equalize again.

Does anyone have any idea why my task manager won't keep my seti setting on normal instead of low? It keeps changing itself back.

Also, what would cause my computer which is on 100% of the time only allow seti to work 13% of the time all of a sudden? It used to be up around 98%. No spyware etc... is running and every time I check my cpu useage, seti is at about 95%. What is going on???

Recheck your General Preferences settings. Is it set to "Do work while computer is in use? yes" ??

Yes it is set to do work while computer is in use. I have checked every setting I can think of....

None this is it...It was working fine several weeks ago, working over 95% of the time and according to task manager, its taking over 95% of my cpu now, every time I check it. But according to my stats on this website, it's only allowed to work 13% of the time and my cpu efficiency is down to .89 or something like that.

Just uninformed speculation: there were some WUs issued recently with incorrect headers, and there were reports of systems ‘spinning their gears’ trying to crunch them. If you got one or more of those, BOINC's time-tracking stats may have been messed up as a consequence. Eric Korpela recently posted a link to a list of the bad WUs somewhere in the Number Crunching forum.

Any ideas on the quickest way to compare that list to the units I've crunched? I was looking earlier today and couldn't see an easy way to compare.

Thanks for the link!

When you look in your list of computers, you see the number of results, yes? Click on that number.
Click on the Work Unit ID number to get to the page showing the result ID.

In Boinc Manager, Tasks window, just enlarge the Name section.
Then check the numbers there against the one in the list.

I use Mozilla Seamonkey as my main browser and know Firefox can do this as well: Just type in for instance 22mr99ab on the open screen which shows the list of bad results. If one of them is found in the list, check the number behind it against your results still active in Boinc. Pressing F3 in the browser will find the next result.

Oh, yes, I meant how to compare to units already processed. The units I have now have been coming and going every 4-7 hours so if I had a bad one, it would have been some time ago. I guess this probably isn't what has caused my low cpu efficency rating and low time seti is processing.
