Hi
I never really looked into statistics, because I'm running a few older computers. But now I saw, that my G5 never got any credits.

Why that?
My two old Mac G4s works properly and also now my new Mac Intel. But the G5 with over 130 Results have only 300 credits.....:-)
Help?
Thanks, best regards

Why that?
There are many Wus with status: Done, sucsess, no credits
That may be the problem with the validator computer. Probably not your fault.

Success only means a result
)
Success only means a result was downloaded, crunched, returned and reported. It has NOTHING to do with validity.
All those returned successfully have been deemed invalid against the quorum. There have also been many returned with error. It seems the machine is not crunching good data, and needs to be checked over.
Since I am currently not in the MAC life, I am unsure what to do to do testing, but it would be good to check that system out, intensively.
What's in the stderr output
)
What's in the stderr output of the "Client error" Tasks you got looks pretty bad, most likely a malfunctioning CPU due to overheating. There is also a small chance that it's "just" a broken harddisk, or the main memory. Whatever causes the Client errors is also probably the reason why even the Tasks that run without crash (i.e. "successful") send back results that are found invalid. Check your machine!

that's surprising for me,

that's surprising for me, because the machine works without problems otherwise.
But anyway, I'm going to install a new system and see what happens.
thanks vor replying.

RE: that's surprising for

A machine can perform fine, when not stressed, eventually it will get bad for the normal things. When a system is stressed in the way these projects ask them to be, it can find more problems. Heat, dust, dirt on the fans/processor/heat sink can cause this. A faulty memory module. The processor itself. Those all could be problematic when stressed.
If you can find good memory and intensive processor testing programs, they can tell you if you have currently an intermintant problem.
RE: that's surprising for

No doubt. It depends on what you normally do with it. BOINC is actually meant to use the resources of your computer that are usually not in use, so it's no so much of a surprise that it discovers errors that don't show up in normal usage. It might be a memory fault in some segment not normally used, or a heating problem that only occurs after hours of heavy use of a certain part of the CPU core that your other programs don't touch. If you're working with pictures or movies or audio data, you may use data formats that are - to some extent - resistant to changes in single bits or bytes, so a memory fault could remain unnoticed.

RE: BOINC is actually meant

Well, actually... Not BOINC itself. :)
The science application running under BOINC will do this. It will put the CPU & memory under load.
Normally, other programs will put the CPU under load as well, but not for prolonged periods of time (say 24 hours). By having the CPU under load, it'll create more heat. Thus you should check if there's dust in the heatsink or fan of your CPU, as when there is, it cannot dissipate the heat correctly and it is capable of throwing out errors.
When it's just sitting there waiting (idling) until something happens, it's hardly doing anything. But put it under a long load and it goes crunching at the maximum speed capable. So the rest of what Bernd says is correct. :)
RE: Well, actually... Not

I was not referring to the BOINC Core Client (which is a program), but to BOINC as a concept of and infrastructure for volunteer computing, thus including e.g. the BOINC projects ;-)
BTW: I know some cluster admins that have Einetein@Home running in the idle time of the machines to detect faulty systems...

HI Thanks for the

HI
Thanks for the information.
I Think there is really a bigger problem. Because I reinstalled everything and also the newest BOINC Client. Still the same Problems.
Now I will du some checks with TechTool and so on, and if this doesn't help, my mac needs a doctor :-(
have a nice weekend
thanks
