I get a client error for about 20% of the work units I have processed. Does anyone else have this kind of problem?

Usually I get some error message about illegal memory reference (null pointer) while calculation and then the work unit is corrupted.

I have Win XP as an OS and Intel CPU.

Do you have other projects running and does BOINC switch between work units? If yes you might try setting "Keep application in memory while preempted" to yes and to no and see if there is a difference. WUs may also fail when your CPU is used 100% from another task over a long period of time. I see you have Pentium M processors so I assume you don't overclock. However you might check your PC for stability running Prime95 torture test.

They are working to resolve a few issues some are having with the graphics display. If you do not display the graphics, this may improve your success rate, until they get a fix.

Also, I wanted to point out that you DO get credit for what you crunched prior to the error. Each completed model is of value to the project, even if there was a failure on the last model it was working on.

To see the credit, wait 24hrs (they run a special program daily that finds the error WUs and grants credit), then display the WU details and you will see the credits.

Well, I do not care so much about the credits but it's a pity if some of the CPU time spent is wasted on the project progress point-of-view.

I put boinc.exe and boincmgr.exe to run on compatibility mode for Win2000 (a hint from some other messageboard) and I started boinc.exe prior boincmgr.exe (another hint, don't know if it's any good)

Let's see what will happen to my failure rate.

Teemu,

Are both your Pentium-M systems laptops, desktops or both? In my experience with laptops & Pentium-M CPUs the one thing that makes all the difference in the world when running something like BOINC is making sure you clean out your heatsink/fan at least monthly. P-Ms handle high heat very well, up to about 90C but you really don't want it to hover around design spec all the time. So if your problem is heat related (I'm not saying it is, but this is a good housekeeping suggestion anyhow) keeping it dust-free can lower your temp 10-15C. When mine starts staying around 85C all the time I know it's time to clean it then the temperarture goes back down to 70-73C under full load.

PS: Are you running boinc as a service or only when a user is logged in?

Teemu, I'm not sure what you mean by "run on compatibility mode for Win2000". That is not listed in any Rosetta instructions. Could you post a link to where you saw that recommendation? Or describe exactly what setting your changed? I mean... compatibility to what?

He's running WinXP, and telling windows to act like Win2k for Boinc.exe and Boincmgr.exe

I'm also running Win XP (on three machines) and have never tweeked such a thing. Perhaps that has added some measure of instability to your running environment as well.

From what I recall about the Compatibility Tab, it basically tells the program the current OS is "X" and passes along settings and so on so the program literally thinks its running on something else. I would imagine there is some very small degree of performance degredation when doing this... considering the overhead of XP pretending to be 2K..

One of the machines I am crunching on 24/7 (amd xp3000+ w/1 gig of ram, running win xp) was giving periodic client errors as well. I cleaned the cpu heatsink and fans. The cpu temp dropped by 10 degrees celcius under a full load(52c). I have not received any client errors as of yet since performing the clean up.

Another machine that is crunching 24/7 (amd xp2200+ w/512 meg of ram, was running win xp at the time) also gave a few client errors. I actually did not figure out the problem until I went to install Ubuntu Linux. While installing Ubuntu, The cd-rom drive was periodically making knocking sounds like it was attempting to access an area outside of the read area of the disc. At first, I thought it was a bad cd-rom drive so I replaced it. I had the same problem with the new cd-rom drive. To my surprise it was a bad IDE cable(cable was being used for the hard drive and cd-rom drive). Once I replaced the IDE cable, I was able to install Linux and has been cruching error free ever since.

This is a little off topic but how do you get a CPU temperature reading while Rosetta is running? I've looked around and can't figure it out. Do you have to get a utility? I have a couple Intel systems and an AMD all running XP.

Thanks,
Bill

RSD Software has a free temp monitor.

Motherboard monitor was/is an application that was used for viewing data like the temperatures reported by the motherboard; if the motherboards you're using are in the Motherboard Monitor's database.

And certain brands of motherboard have their own utilities for displaying temperature. I've used the ones that came with my Asus (before the default voltage on my Asus motherboard helped fry my Athlon XP cpu years ago..) and MSI motherboards.
So there's a few different sources for cpu and case temperature information.

A fantastic program for Pentium-M/Centrino (and newer) systems is Notebook Hardware Control. They also have added support for AMD systems recently and it's getting better. It's a fantastic, low overhead, very detailed monitoring program (and looks cool too). And it's free..

Thanks for the advice. I always try and keep my systems dust free but I'd never know if one was getting too hot until it was too late. I'll look into the 3rd party temp. monitors.

Thanks again,
Bill
