Now, why would a client error even have credits? Half of his WUs are client errors.

Because most of the \"client errors\" are in reality \"application bugs\"?

It would be nice if the trickle mechansim used by the climate predictor were available in all the projects...

But please correct the restarting-bug first.

Why did two people get credit
because they sent the same result
and I did not?
because your host sent something else.

I would say that only the wus created before 4 dec. (not sure about time) got the new policy (max # of error/total/success results 10/20/10).

Look at WU27119 from October.

Also noticed granted credit for invalid results and \"Workunit error - check skipped\" results, and even the empty results, Thanks again Adam!

What\'s still missing is the credits for \"Maximum CPU time exceeded\".

Only when 3 identical results are sent in, we can say that the quorum of 3 is met.
Look at http://szdg.lpds.sztaki.hu/szdg/workunit.php?wuid=21173. 2 of 3 seems to be enough to validate. If you look at the stderr of the results it even seems a bit funny which results are valid.

7) Message boards : SZTAKI Desktop Grid : error: Output is empty (Message 4898)

Some people have suggested that, to get a WU going again after seemingly being stuck for a long time, one just needs to exit and restart BOINC. This will allow the WU to magically jump ahead and resume, but I am afraid it also causes the empty output.

Even if it doesn\'t produce an empty output line, I think you can be quite sure that those \"jumping\" WUs will not validate. There must be something wrong in the restart logic.

8) Message boards : SZTAKI Desktop Grid : Lost credit/cycles due to time constraints (Message 4587)

I don’t think there’s anything the project can do about those; I believe the CPU-time error is a ‘failsafe’ in the BOINC client itself.

The time constraints are set by the project when generating the WUs. So the errors are triggered by wrong estimations of runtime. Granting credits for those is not rocket science (and it has been done by e.g. Rosetta all the time until they implemented their own watchdog).

Yesterday, I returned this work unit which bombed at 206hours. I left it running as it is a two liner (I think) that went to 50% at about 80h and I thought it would be okay. Next time I check the computer, I have a cpu time exceeded message. :(

Same with this. Only difference is, that the first 50% took about 2 hours, the remaining 160+ hours the host crunched the second line. I hope, that the credits will be granted, because those \"CPU time exceeded\" errors are errors on the projects side and not on the client.

Computer merging error has been fixed, computers can be merged again.

And now, please, update the server software, so that not a new entry is created at every contact for some hosts.

Norbert (yes, I know about editing my .xml file to correct this serverside bug)
