Ok i decided to be daring and i attached to Climate prediction. First just let me say I AM SHOCKED IT IS GOING TO TAKE 2200 HRS FOR ONE WU! .... ok now that thats out of my system heres the question.

I dont understand how time is divided between the two projects, i cant figure out if resource share does that or switch between projects every xx minutes does it. I basically want Seti running 75% of the time and CPDN only 25%, can someone tell me how to set that up?

thanks

You'll need to set up the preferences on each project. Go to Your Account, then the Project Preferences. For each project you'll need to set up the preferencs so that you get the %ages you want. Because it works on the basis of the sum of all the preferences, you can set SETI for 75 and CPDN for 25, or 18/6, or any numbers such that the ratio between them is 3 to 1. Each time you change the preferences, update that project from BOINC Manager.

So do they both run at the same time and seti gets 75% cpu and CPDN gets 25% cpu? Or does seti run for say 75 minutes, then CPDN runs for 25 minutes??

They take turns at the CPU using the switch time set your account preference. It wont be obvious for a little while, as in the short term it sometime looks like one project is hogging the CPU, but overall the ratio will end up 3 to 1

If BOINC is running in Round Robin mode, you should expect S@H to run for 180 minutes (assuming the default for switch between applications) and then CPDN to run for 60 minutes.

However, if a deadline is in danger of being missed, BOINC will run in Earliest EDeadline First and will not switch away from the result with the earliest deadline until the danger of a missed deadline is past (either by finishing the result or by completing enough so that the danger is over). If the host enters EDF, the projects that get the extra time build up a balance that is owed to the other projects. It is payed back later by not downloading from that project until the debt is payed back.

[So do they both run at the same time and seti gets 75% cpu and CPDN gets 25% cpu? Or does seti run for say 75 minutes, then CPDN runs for 25 minutes??

In General Preferences, the default setting for "Switch between applications every" is 60 minutes. Every sixty minutes, BOINC will recalc the short-term debt and see which project needs time. If you're just running the two projects with a 72/25 resource share, generally you seel SETI run for three hours, then CPDN for one hour, and repeat. There are other times that the schedule gets recalculated, so it won't be exactly that, but in general that's what you'll see. Let it run, and BOINC will honor your resource shares and make sure that you don't go over deadline on the work.

Ok just for the sake of getting it to run i set the switch between projects to 1 minute, but it isnt switching. i have like 30 setiathome WUs stacked up ahead of the CPDN WU. Do those have to complete before it starts to work too?

No, they don't have to complete unless they're too tight on deadline. I'd suggest setting it back to sixty minutes, and let it run overnight. You should see how it switches off when you come back.

[edit](Did you update BOINC Manager for both SETI and CPDN? You show a lot more than 30 results outstanding on each of your computers right now.)[/edit]

Since the basic question was answered, I will move onto an aspect you did not ask ...

Though the work unit takes months, you will get credit based on "trickles" returned to the project. You also have a one year deadline, and if you are still trickling it is not rigeerously enforced. So ...

There are, if I recall correctly 150 trickles in the sulfur models, 72 in the older slab (which may come back), and the next generations of models will have other reporting intervals. In comparison, the models take about a full week of supercomputer time ... so, regardless of where they are run, they are long ... :)

Me, I just think that it is neat that I can do work that used to ONLY be able to be done on a supercomputer ...

Oh, and Chris is updating the CPDN pages in the Wiki so there is some really good information in there ...

LOL i took a glance and guessed, quite badly apparently. Now that i look its more around 70 or so :D (how i love my 10 day cache). But theres only 1 for CPDN thank God.

I set it back to 60 and ill see wat happens over night. Thanks to everyone, this is the fastest responding forum ive ever seen.

(how i love my 10 day cache). But theres only 1 for CPDN thank God.

a) Set CPDN for "no new work" - you REALLY don't want to get a second one on there...

b) If you have your machine set for a 10 day cache, you are forcing it into EDF mode ALL the time - therefore it will NOT do "round-robin", SETI and CPDN. It will do only SETI, continuously, until the cache is empty. Then it will do CPDN for 1/3 as long as it ran SETI, then it will get more SETI work, and repeat. This is NOT GOOD. Lower your cache size. To work properly with two projects, it MUST be 5.6 days or less. Let's face it - with 2200 hours of CPDN to do, you are _not_ going to run out of work if SETI is down for a day or two.

c) Once you've lowered the cache size, it will still do SETI-only until the work on hand drops below 5.6 days.

Oh, heavens ... I did not notice that ...

Yes, there is little reason to run with a large cache if you have a CPDN work unit and only single CPU systems. Heck, there is little reason with 2 or more projects going over a day or so. And that only to "bridge" local outages.

In your case there is no reason to be over a 1 day cache ... mostly what you do with a large cache is make it so that you will always be "pushing" your work back up manually, and not getting work back and fretting about it ...

O Wow......

Advice taken. thanks! :D

alright, well today was the first day this computer started processing CPDN. Its been going for a good four hours now. But i have a question. Why does the CPDN screen saver not work right? I can hit the show graphic button and it will come up, but when the actual screen saver comes on after the computer is idle the screen is just blank. I would expect this from SETI as i have the optimized client, but neither my BOINC application nor CPDN are optimized so why does the screensaver not show? I even put CPDN on my other computer and forced it to run, but the screen saver still doesnt show on that one either.

A little thing i noticed when i hit the show graphics button. as i said before this is the only place i can actually see the CPDN screensaver working. The graphics for CPDN seem to take away a hefty 20% of my cpu. While thats a lot of time taken away from the project i dont really care, i like the screen saver! Could it be that my graphics card is not powerful enough?? Its an Nvidia Gforce 440GO card with 32mb memory.

While there are lots of people here running multiple projects, you'll probably have a better chance of a quicker answer if you post this at the CPDN site.
