	Yesterday, during the scheduled downtime, I decided to add a second project on one of my pc, so as to have it do some work while Seti was unavailable. I chose climateprediction. WU's for this particular project are, well, huge. Several hundred hours of computing time. Anyway, I'm happy to help, even in this small manner. The thing, however, is that Seti has stopped sending WU's to this computer. Could it be that Seti thinks that this machine is too busy? I have two projects, 50% of resources allocated to each, no restrictions. My other pc has been receiving WU's from Seti normally. Any ideas? Thank you in advance for your time. ____________

	Your computer is hidden, so we have no idea whether it is fast, slow, or middling - though from your total credit/RAC so far, I'd guess it was towards the slower end of the range. Have a look at the back-of-an-envelope figures I gave Darren and squeak in the BOINC not switching out of climateprediction thread - your situation is very similar.

Would it help if I "unveiled" my computers? I'll do it regardless, I was just trying out the various options in the preferences. I'll read the info in the tread you provided. Thank you. ____________

How long does BOINC think that the CPDN Wu will take? What is the deadline? What are the LTD values? ____________ BOINC WIKI

	How long does BOINC think that the CPDN Wu will take? What is the deadline? What are the LTD values? Currently, BOINC calculates that it will a little less than 1,860 hours to complete the CDPN WU. Deadline is set for February 24, 2008. It took my AMD Athlon 3500 (2 gigs of RAM) roughly 19 hours to complete 1.71 HadSM3 Model-Years according to my account card. I don't mind credits, whether I get more or fewer than I would otherwise. My only concern is that since ClimatePrediction took over (during the scheduled downtime on Tuesday), Seti has stopped sending this pc WU's and I really don't want to give up Seti. ____________

	How long does BOINC think that the CPDN Wu will take? What is the deadline? What are the LTD values? Currently, BOINC calculates that it will a little less than 1,860 hours to complete the CDPN WU. Deadline is set for February 24, 2008. 77 days, or two and a half months. No deadline problem there, then .... .... *provided that* the computer is on, and available to crunch for BOINC, an adequate proportion of the time. You need to do 2.5 months crunching in about 11 months, so you need to have a crunch efficiency of about 25% or just under. What figures do you see for % of time BOINC client is running While BOINC running, % of time work is allowed Average CPU efficiency when you look at the details of your PC on this website? (even though you've unveiled your computers now - thank you - these figures are only visible to the account-holder). If the efficiency figure is around the 25% you need to reach the CPDN deadline, or lower, then I'm afraid BOINC will think you haven't got any spare time left over for SETI.

If the efficiency figure is around the 25% you need to reach the CPDN deadline, or lower, then I'm afraid BOINC will think you haven't got any spare time left over for SETI. Here are the stats you asked for: % of time BOINC is running: 21.7272% While BOINC running, % of time work is allowed: 97.0315% Average CPU efficiency 0.900626 So, basically, it looks like I'm barely going to make that deadline..Guess I'll have to leave the pc running a little longer to compensate... Once again, thank you for taking the time to help out. ____________

Once again, thank you for taking the time to help out. Do not leave, if you feel comfortable editing files I think there is a file you can edit to change the numbers. I do not know what it is, but someone should be able to tell you. ____________

Once again, thank you for taking the time to help out. It's your % of time BOINC is running stat that is keeping you down. BOINC thinks you only run science apps almost 22% of the time. Since ClimatePrediction WUs are large, BOINC wants to make sure it isn't late so it's going to put a hold on everything else until it realizes that it's not going to be late. During this time, it's going to be building up debt to your other projects specified (in this case, SETI@Home). Once it's cleat to BOINC that ClimatePrediction is going to be OK, more SETI work will be downloaded an crunched, thus satisfying the built-up debt. About the % of time BOINC is running, do you turn off this machine or does it run 24/7? If it runs all the time, then that number should be higher (unless you manually exit BOINC most of the time). ____________

	I left the pc running a little longer today. Sadly, I can't leave it running 24/7, but at the very least I'm working on this pc 10 hours/day (in which time it should be doing some number crunching, since I've set aside 50% of memory for BOINC even when I'm using the pc) and then leave it alone to do some number crunching several more hours. Currently, my % of time BOINC is running is up to 28.08%. Still, SETI thinks this pc is too busy. Right now, every 24 hours of real-time work translate to 1% of project progress, so it's still touch and go in terms of making the deadline. Regardless, thanks to everyone who's taken the time to respond. ____________

Regardless, thanks to everyone who's taken the time to respond. Fortunately, CPDN does not insist on meeting the deadlines. The BOINC client does not know that however. CPDN just wants to see at least one trickle every couple of weeks. BTW, after you are done with CPDN, BOINC is not going to download a new one for a very long time. ____________ BOINC WIKI
