Message 42763 - Posted: 11 Oct 2010, 18:47:09 UTC

Had 4 WU's errored out after 55+ hours here is one:

http://milkyway.cs.rpi.edu/milkyway/result.php?resultid=214612877

Any idea what caused this?

I have also had three separate packets error out with computational errors in the last few days. It is a little worrisome.

Ive had that same problem with my mac and the i7. They crunch for 32 hours and are allmost done then get a comp error. Kind of ticks me off. So have set both for NNT and will let them die.

Ditto. My last two units computed for over twenty hours each and then were called 'computational errors' and my computer got no credit for the time. Pisses me off, to be honest. I'm seriously thinking of abandoning Milky Way if this keeps up.

Message 42786 - Posted: 12 Oct 2010, 15:19:43 UTC

In the last few days I have had four computational errors with MW@H O.O4 with the following properties on the latest two.

Task de_16_2s_5_265369_1286519163_1 de_12_2s_5_269934_1286519188_0
CPU time 24:35:08 25:42:16
Elapsed 25:23:30 27:26:07

From what I read here this is not an isolated event what is happening with MW@H?
I am also having issues with the SETI people and their server problems and this leads me to question the whole BOINC effort that I am making with my meagre resources. What is the point of me wasting power for something that leads to an error? If they have sent out a batch of WUs that cannot be calculated then they should tell us that that is what they are doing.

Does anybody know what is going on?

I believe that Seti is another issue, a server went bad. At Mw a portion of the latest wu's are erroring out. It is not all of them but a good number. This last weekend I had 5 out of 18 that were bad. I guess it isn't considered bad enough to cancel and start a new batch.

As for Boinc it is what you make of it. So projects have done some good, others are just basically busy work.

If it makes sense, DON'T do it.

Fair enough Banditwolf. None of us do this for anything but the satisfaction of donating our spare computing time to a project. Its not that I, with with a tiny E4700 core duo processor, am chasing WUs. Its just very annoying to see 100+ hours of effort go to waste. But it will be the same for everyone and sometimes a null result can steer the investigators in another direction.

I am not complaining overmuch its just that I have had bad luck recently with both my BOINC projects. If it continues I may try some different projects which are not so error prone as I wasted a lot of time chasing around to see whether the error was at my end.

Yes the one that had 2 hours to go also ended up with comp error. So I aborted the remaining 4 WU's... no point wasting anymore time. I switch back to WCG. Maybe some can find out what the problem is or was!

Errors will occur at times but your contribution to this research is important. Ignore any negative comments about the fact that you mentioned you didn't get credit. It happens to all of us. The credits give us an idea of our contribution to the research. Those that could care less about credit should not insult those that like to see it. I know I would have been concerned if after 14 years or more of studying I didn't receive my degree's in Astronomy and Education and a professor said, "hey your not here for the credit" but thanks for all those hard years of work for nothing, that would have made no sense.
I'm sure Travis will work the bugs out so keep crunching and don't get discouraged because your time is appreciated I'm sure. :)

I'm sure he will. But until he does, MilkyWay@Home is no longer getting my CPU time. (GPU work units still work and these are still enabled.)

This is not merely a minor annoyance that aborts a small percentage of the CPU-only work units. It's all of them (for me) and it wastes CPU weeks that could be productively used for other research projects. To add insult to injury, the new work units (for reasons unknown) typically run twice as long on Windows as the old version 0.19 did before they now blow up trying to return results to the server.

I understand. I get annoyed when I loose a few hours or all day when a wu goes bad. I don't have much processing power either with a pentium 4. I stick with MW and Rosetta and both have had some problems lately. Last weekend both ran out of work. In the last month it seems that if one has problems the other does too. I'm sure you'll have better luck in the future.

Maybe I missed it, but I don't see anything from the folks who run this project explaining what's going on. It's beginning to remind of how the airlines don't give out information even after your flight has been delayed for hours or canceled altogether. I'm taking another flight (Einstein, Spinhenge, etc.) so to speak, but checking in here from time to time to see what's happening.

How about some information? And in language that us non-computer experts can understand?

That's because the folks don't have a clue either, which is one major part of the issue itself... None of them is really running/testing any of their own apps.

As for the latest screw up... If only one of those developers would have had a look at one of those error messages of the latest icarnation of the MW app... it would have been interesting to know why a CPU app suddenly identifies itself as a "stock_win32_gpu"...

Everything was fine with Milkyway until MW@H O.O4 was rolled out and all of my WUs have been ending up with computational errors with no credits awarded for the CPU time invested.

I am fed up with this situation so I have aborted all of the WUs in my queue. If I am not going to get any credits for the time invested, then I might as well donate my CPU time on a BONIC project where I will be rewarded for the CPU time that I have donated.

That's quite interesting. If we take a look at one of those results :

<message>
<file_xfer_error>
<file_name>de_14_2s_5_1054160_1286929219_0_0</file_name>
<error_code>-161</error_code>
</file_xfer_error>

So that means that the app itself expected to have a result file <file_name>de_14_2s_5_1054160_1286929219_0_0</file_name>...

Now cosidering that the new code logs it's results directly into "stderr" and doesn't create the usual result file associated with it, the boinc client now "thinks" that the app didn't finnish properly (missing result file) and reports the WU back as an tranfer error although everything finnished just fine.
