Can someone help me understand the relationship (if any) between the percent of the CPU Seti is using and the "priority" it is given in Windows? For example, I see that Seti (by default) is set to a run as a "low" priority. When I change this to "high" my system obviously slows to a crawl and is almost unresponsive (makes sense since seti would be getting all the attention). What I don't get is that if seti is set to low or high or anywhere in between, it always looks like seti is using 99% of my cpu. Am I the only one that is confused by that?

Ron, Probably not ... lots of people are confused, but don't ask ... Ok, priority means who gets to run when ... Usage indicates who IS running. BOINC/SETI@Home are set to run at low priority when nothing else is running. SO, if you are not doing much, SETI time will be 98-99% ... move the mouse, open a window and that time will drop ... but since it is using "idle" time, you don't see a slow down. Making BOINC High prioity means it will run at the expense of evereything else. There is no reason to change the priority of BOINC/SETI@Home (or any other science app) to anything else... it works right out of the box as designed ... [edit] Goto my web site, click on search and enter Priority, read the entries and see if that helps more ... ID: 92940 · |

Actually, your response was worded perfectly and made total sense.

> Actually, your response was worded perfectly and made total sense. Thanks! Am I good, or what! :) The only reason I was twisting your arm is that we have been collecting the "wisdom" for some time and it all on "paper" as best as we can (if you look close a lot of stuff has other people's names on it - that is because they can explain it better than I). Looking some of this up on your own saves repitition ... :) Anyway, I am glad we cleared up your question. ID: 93272 · |
