May I also say, I am a little envious of the computer power you are bring with you.

No need to. I actually need these computers for work. 5 of them are at the office anyway. The FX, of course, is my gaming rig (and therfore not really necessary ;) ).

Again, welcome to you and All of the new members.

Thanks again for the warm welcome.

Keep crunching,

Jochen

Why recuce cache size,"Connect to network about every:", when you increase WU time?
Wouldn't the increase in connection to network time also increase your bandwidth usage? And is your bandwidth usage costing you in money, as in you pay by the bandwidth, or is it just so you don't slow down your internet connection to a crawl?
Mine is set to connect to network every 0.1 days, that is what it is on default. What is the most preferred?
While I have been running the Rosetta stuff for a few days now continually, and probably will for the weekend, I won't be able to do that all the time. I have to keep my electric bill as low as I can, so I will only be running it, later on, when I am home from work. Maybe 6 or 8 hours at most every day.

It would be nice if there was a preferred user setting based on different amounts of time. And example...."If you are connected and running Rosetta 24/7 then use these settings, if you are connected 8 hours or so a day, use these settings, if you are connected for 1-3 hours a day (reading e-mails,news or a little bit of work) use these settings, if you are dial up only, use these settings".... So on and so forth. It would greatly simplify things for different people and groups. Is a rework of the Q&A to something like this feasable?

Cache size can be set so that your system can go multiple days without connecting to the Rosetta servers. >IF< you have WU time set to 3 hours (the default now), and you had a 3 day cache, then the cache would hold around 24 WUs. If you then change your WU time to 6 hours, you'll now have 6 days worth of WUs in your cache. After a few days, Boinc will figure out that the WUs are taking 6 hours to complete, not the original 3 hours, and you'll end up with around 12 WUs in your cache (back to 3 days worth.) If you reduce your cache size while increasing the WU time, then Boinc won't be conned into downloading any more WUs until it's chewed threw most of the 24 in your cache and figured out that they now use your current WU time setting (be it 4,6,8,12,16,24 hours) That's why it's recommended that people with large caches change their WU times in gradual steps..

By changing my WU time to 24 hours, I download 1 2.3meg file, and crunch away on it for about 24 hours and then upload the results. (I don't remember the size of the uploads.) If I was using a WU time of 3 hours, I'd be downloading 8 ea 2.3meg files, and uploading 8 sets of results. I reduce the bandwidth usage of the Rosetta server to 1/8th of what I could be using with the default setting.

Prior to starting Rosetta, I'd spent years on the local cable modem service to Kodiak Island - and was getting 512k down, 128kup with a bandwidth usage cap of 8gigs/mo. Every gig above 8 was $20/gig.

I'd started Rosetta and switched to a slower DSL link with unlimited bandwidth - (for better connectivity - i.e. the cable modem kept dropping out twice a day during Emergency broadcast tests) - and didn't get to use my system for a few weeks and noticed that Rosetta used up 250megs in 5 days, and then by the 2 week point, had eaten up 1Gig. (An extra 2Gigs a month would have put me over my bandwidth usage cap during the months I was actually using my system.) Now that the size of the WU downloads has been reduced by half, and the WU time can be set up to 24hours, it's possible to only use up 3? megs a day. (And we're still waiting for compression to reduce that total even further.. :)

3 hour WUs would not cause my system or my download speed any problems - but by reducing the amount of the Rosetta server bandwidth I'm using, I leave more that others can use.

As for the default 0.1 Day connection time - that allows your system to upload your finished results within 2.5 hours, and unless you want a larger cache size, leave it that way. For larger cache settings, and perhaps changing Boinc so that it only connects during the evening, or other non standard connection options, take a quick look through the FAQ.

As for a general rule for WU time length, I'd suggest picking a WU time that would allow them to be uploaded every day or two. If the system is only on for 3 hours a day, then don't pick a WU time over 6 hours. Reduce it further if Rosetta is only setup to run as a screensaver when the system isn't being used.

The more of us that reduce our downloads to 1-3 a day, the easier we'll be on the poor Rosetta Server. :)

have quad core phenom 9850. is there a way to optimize cpu time for maximum science? i don't care much about credit, just optimum use of cpu times. am running seti@home, world community grid, and orbit@home, also.

bo, just try to allow BOINC as many resources as you can without interfering with other work. And be sure to leave tasks in memory while suspended. Maybe up the time between switching tasks to 3 hours rather then 1. You can reduce your network usage if you up your Rosetta preference for runtime per task. Default is 3hrs, you can go as high as 24hrs. I suggest gradual change to this number. Maybe two notches per day. Also, only make change to that when you do not have many tasks downloaded already, because they all will inherit the new runtime preference. By going gradually, BOINC gets to see they run longer and requests fewer tasks over the course.

P.S. increase your resource share in your Rosetta preferences ;)
Oh, and the graphics is just for your benefit, not the science. So, turn it off, use a screensaver that doesn't consume lots of CPU (like the ones that are always in motion do).

Check what percentage of CPU time you are set up to use; I believe that default is 60% in order to avoid overheating notebooks and computers in a hot environment. I changed it to 100% and can still run programs that are not CPU-hungry at the same time as BOINC projects, since the programs I start run at a higher priority than those BOINC starts.

On my machine, I found that adding more and faster memory also helped.

Also, there's a limit on the number or CPU cores in a multi-core machine you use; make sure you have it set high enough to use all the cores you have, but it's often a good idea to set it low enough that it does not use hyperthreading on any cores that support hyperthreading.

Depends on what BOINC project you joined first. If it was World Community Grid, the default it 60% like it was for me.
