I figure we can probably share our configurations on client preferences to see if we can optimize the results that are performed on a daily basis.

Currently I\'m running on 3 projects: Einstein, Rosetta, and BURP.

Optimally I\'d like to just pick one to really pound the compute cycles but each time I do this the project(s) go offline for a while and I have wasted CPU cycles...

here is my preferences for my \"STANDARD CRUNCHER\"

STANDARD CRUNCHER

Is this the default preference? Yes

Processor usage
Do work while computer is running on batteries? No
Do work while computer is in use? Yes
Do work only after computer is idle for -
Do work only between the hours of no restriction
Leave applications in memory while preempted? No
Switch between applications every 15 minutes
On a multiprocessor system, use at most 16 processors
Use at most 95% of CPU time
Storage and memory usage
Use no more than 100.0 Gb
Leave at least 1.5 Gb free
Use no more than 50% of total disk space
Write to disk at most every 30 seconds
Use no more than 75% of total virtual memory
Use at most 0% of memory when computer is in use
Use at most 0% of memory when computer is idle
Network usage
Connect to network about every 0.01 days
Maintain enough work for an additional 0.5 days
Confirm before connecting to Internet? No
Disconnect when done? Yes
Maximum download rate: No limit
Maximum upload rate: No limit
Use network only between the hours of no restriction
Skip image file verification? No


what settings do you use, and why?
do you see anything in my setup that could cause issues?

Happy Crunching!

I was only running BURP, LHC and Rosetta (only one of which has work all the time), but I decided to add a few more projects, just in case Rosetta runs out of work--and to give backup work to my Mac clients. So, I\'ve added Einstein and SIMAP. BURP, of course, is set to a resource share of 1000 while the other projects are only 1-10.

As far as preferences go, I\'m just using the defaults. I do have two sets; one for my laptop and one for everything else--the laptop is limited to 1 CPU for heat reasons, the others aren\'t. Of course, it doesn\'t really matter anyways since I gave up my only (true) dual-core machine.

default except for the following:

Network usage
Computer is connected to the Internet about every
(Leave blank or 0 if always connected.
BOINC will try to maintain at least this much work.) .1 days
Maintain enough work for an additional
(Requires 5.10+ client.) 0.25 days

I run SETI, Spinhenge, Enigma, TSP, and BURP.

Resource share is 25/25/25/25/5

Have to set it that way due to being on dialup via ICS and can\'t micromanage BURP when I\'m at work.

Even though I keep the .25 cache, I have 85 hours of work on hand (per BoincLogX)

Leave applications in memory while preempted? No
Switch between applications every 15 minutes

Not leaving in memory means that the project will restart crunching from the last checkpoint. Some projects might not have checkpointed in the 15 minutes you\'ve allowed, so you may be losing all that crunch time - until Boinc sees the project nearing deadline and starts giving more cycles of 15 minutes to it. I don\'t think that Boinc will wait for a checkpoint before switching.

Leaving in memory is not as bad as one may think as this gets moved to the swap file as other applications request RAM - but still affects performance as it is swapped out and swapped back.
I would suggest leaving in memory, but setting the switch interval to a bit higher than the typical run time of your projects. This way you don\'t get many projects actually left in memory.


Use no more than 75% of total virtual memory
Use at most 0% of memory when computer is in use
Use at most 0% of memory when computer is idle


0% ?
How soes Boinc do anything with 0% ?
But I assume you are crunching, so any more knowledgeable person know more about this?

Somewhere in the 5.6.x range BOINC started waiting for the next checkpoint to switch projects. It is still good advice to increase the switch time though, I like the default 1 hour for this one.

I would expect 0% memory usage to cause the client to idle as well. I have not tried it though.

Using the Preferences setting in Boinc Manager I tried 0%. It turned that into 100% so I guess xPOD is actually running at 100%.

For interest sake I tried 1% which on my 1GB host allowed 10.23MB. Seti started a WU and 10 seconds later errored with the following message:

2008/03/11 14:24:33|SETI@home|Aborting task 13fe08ac.31246.8252.10.7.52_2: exceeded memory limit 21.31MB > 10.23MB

Pity it stsrted the WU without checking the amount of memory available! Oh well, I write it off to a gain in knowledge...

I have the same settings as yours, einstien, seti, and rosetta. CPU usage is 90% for seti and 10% for the other 2 projects.

My current credit per day dist is 40%, 30%, 30%, but burp should be higher than that, considering there are a lot of pending credits right now.
