One thing I have noticed is that when I close BOINC, I sometimes lose communication with the client. I will keep it open and minimized like I used to, but with only active tasks showing, and on the statistics tab. It should be safe that way.

My rig stalled last night in it's leap forward, but it added about 13,000 in pendings. It seems to be taking off again, and the pendings are only going up a little bit.

It made a small but noticible difference on mine Robert. Bigger crunchers(bigger list) I am sure it makes a larger difference.

I set mine to show active, I can flip it to show all tasks when I want to look.

Yesterday I running this machine with NNT set, cache was around 1400 units, I removed NNT on SETI before retiring. This morning it had built up to 2900 units, I had an avi file running on Nero Showtime (old epp of law and order) and I flipped to show all tasks, the effect on the avi (slowdown jumping) was similar to running a VLAR on graphics card, I was not seeing this affect yesterday with less units in cache.

most of my machine's had boinc manager off
the two that were still running with it on show no increase

maybe it's because I use boincview to look at them

any case I've shut down boinc view unless I'm taking a look
(it has an option how often you query the clients)

Yeah I've been doing the same thing for a while. But I never have quite the number they have in their view. Largest number I've seen any of my rigs gets up to was am 1800 WU cache when I had it set to 10/10 on the cache settings. So I don't think it has as big of an effect on my machines. But I also, like you, use BoincTasks to check my machines out with a slower query time. Same principle different program, so I suppose I must have been doing it right too!

Of course, if you close BOINC, the manager loses connection with the client. BOINC is the client, and if it's closed, it's incommunicado!

You need to close BOINCMGR, and leave BOINC running - best through the File|Exit menu, having previously set the exit options correctly to leave the core client running when the manager exits.

Or better still, get yourself a cheap netbook for browsing this messageboard - then do like Robert and I do, use the netbook to run BoincView or one of the newer alternatives for task monitoring. I have BV set to check all my hosts every 30 seconds, rather than every second as BOINC Manager does.

If you ever need to run BOINC Manager locally to check something, you may find it takes a few seconds to reconnect to the BOINC client (especially with your cache size - that's where we came in), but it should get there eventually.

I meant BOINC Manager, but got distracted and forgot the manager part. (Cat walking on keyboard) I left it closed today while I was at work, and had no communication when I got home. I shut down BOINC client, and restarted it. When the Manager came up it was fine, but as soon as I closed it, I lost communication again. I did it again with the same results, so I figured I'd leave BOINC Manager open and minimized with it on the ststistics tab, and with only active tasks. So far it's working as expected, except I seem to be building pendings again. I know that doesn't matter, I just liked seeing it climb.

With this latest change, I should pass my previous personel best RAC of 47,000 in a few hours. Even though I am crunching AP units at the moment, the GPU's are dominating by a large margine, and my RAC is climbing fast.

Thank You Jason!

Steve

You are now into the 55k RAC now, is this just from the effects of Boinc manager or other improvements?

A lot of my current RAC is due to keeping Boinc Manager closed, or at least showing only active tasks. It would be higher, except that in the last two days, I have added over 20,000 in pendings, and only gained minimal RAC. I have made no changes since I made the boinc adjustment. It drastically reduced my crunch times. This is based on a 3500± cache. Smaller caches would have less impact, and larger ones would have a greater impact.

It seemed I was stalling around the high 10,000 on rac when i clicked on all the just show active tasks. I am now in the low 12,000s and still climbing. Was it due to that simple act? Once my rac starts to stableize and levels out I will click on the show all tasks for all 3 of my computers and see what happens.

Ill let you know when I start that. Should be interesting to find out.

I think Jason's opening post accurately describes what happens. The CPU is kept busy refreshing the task list, which bleeds resources from the GPU(s). Their output is noticably lower with all tasks displayed.

I am still waiting for my RAC to stabilise after all of hardware changes.

While playing I had noticed the affect of cache size on pendings, increasing cache size then moving unwanteds to CPU and setting NNT before checking tasks done over set time period. Letting wingmen have a chance to return results does decrease pendings.

I think he is correct. But I have just a 1 day cache on my machines.I can see if I had megawads of work units stuffed away:) Still a nice thing to try out.

This was an effect noticed way back in the days of SETI Classic, when the famous screen saver was run to show progress in that work unit. When the screen saver was switched off the CPU crunched the WU in about 55% to 60% of the time it took when the screen saver was running.

Taking unnecessary loads/refreshes off the CPU will increase the science.

Damn, I wish I could install Windows 3.1 on my current box and there was a Boinc version for it. ;)

Eck 3.1! I was thinking more along the lines of a bootable flash drive that only loads and runs Seti@Home along with Cuda support and networking. Something like BOINCpe Live-CD. Unfortunately I need my other box for more than BOINC or I would give it a try, don't think it would support CUDA either though.
