I hope that computation errors are examined for problem resolutions. I am tired of wasted CPU time on work units that end up in errors.

have you checked that your computer is stable?
and that it meets the minimum system requirements?

All of my 10 completed workunits have resulted in a client error also.
They are not part of the bad batch of workunits.
I have been able to complete workunits for einstein and predictor, so my computer should be stable.
What is the problem?

not so, a computer that can do SETI without error might not be able to do CPDN because the processing CPDN requires is far more intense, did you actually run thru the list of suggestions on the list that the link went to?

What is the problem?

Plasmo, if you check in your results and check what other computers returned for the same workunits that you did, and most if not all of them were sucessful and granted credit, then it is most likely your computer, rather than a problem with the app or workunits

so do the suggestions from the "is your computer stable" as this will really test how well your computer performs under stress

from what i remember, if it's a problem with your particular host then it's most likely something wrong with the hardware, overclocking, or heat related problems and insufficient cooling

Iv had been running boinc with just 'seti@home' for a few months with no problums what so ever & have just resently added both the 'BBC/CCE' & 'Rosetta' projects for a total of three projects.

now with both the BBC/CCE & rosetta projects im having thease 'Computation Error's' every day,real bad with the rosetta project.

WHATS UP WIT DAT?!

what is a "Computation Error" & what is causing this pls & ty? :-)
_______________________________________________________________________________

"have you checked that your computer is stable?" = NO.

im using a gaming computer that plays HUGELY graphically intensive 'massive muti-player online games' with no problum, if my puter cant handle rosetta?! then i give up! LOL!.

in your general preferences, make sure you've set "Leave applications in memory while preempted?" to "yes"

also if the problems only occour when you're gaming, then set boinc to "run based on preferences" or suspend it if you're using a game controller (something other than the mouse/keyboad)

there is a vast difference between gaming and the kind of processing rosetta does, gaming is relatively easy, and it doesn't matter too much if errors occour, rosetta on the other hand is very sensitive to errors, and uses parts of your CPU that a game will not
so a game may work perfectly, but it doesn't mean your system is stable enough to run rosetta

run thru the list of items on the stability check list as this will identify the most likely source of the problem

for questions such as "what is a computation error?" please read the BOINC Wiki, but basically it means that something went wrong with the calculations, and the most likely cause is a hardware related issue (cooling or overclocking ususally)

please suspend any projects that are resulting in lots of errors until the problem has been resolved, because it just slows things down, and you might as well crunch for a project that gives good results

actually thinking about it, do you return good results to seti?
go to your (SETI) account, click the "my results" link and check that you're being granted credit, and you're returning valid results

@lee-

TY for your responce.

"Leave applications in memory while preempted?",was set on NO,changed it to yes.

as far as tests, i went to PCPITSTOP.com & did their FULL TEST & everything including my memory passed with flying colours. no idea how thorough their tests are.

AFTER THAT i updated my ATI display drivers.

now it SEEMS to be running ok since then,on the BBC/CCE forum someone looked at the error # or whatever & said they thought it might have something to do with the display drivers & other users who had went & updated their drivers seemed to cure the problum,well it SEEMS to have worked for me also. time will tell,so far so good.

& BTW, i always suspend BOTH network activity & boinc whenever playing my online games.

if it's working now then good :)
i'm not sure about their tests either, but if you have any further trouble run thru UKnicks list of tests, they're pretty through, and will find any hardware issues, they're the tests i recommend to everyone

the issue with graphics drivers is interesting, i never would have thought graphics drivers would have caused rosetta to crash, but that's computers for you lol

anyway, happy crunching
