OK I've turned on work fetch again but there are no WU's to download a.t.m.

They take while, almost to the completion stage in some cases then suddenly the status changes to 'Computation failed' & progress zips to 100% and all I can do is update to get rid of them..

Computation failed. the weird thing is that the log doesn't say that, it says merely that it finished. Weird.

Message 49074 - Posted: 27 May 2011, 14:26:35 UTC - in response to Message 49058.  

I see now that it's vanished from the work unit progress page here, why do they delete them so quickly? It serves no purpose except perhaps drive us insane.

I now have subsequent units in progress, so far so good, and those are all that now show there.

So unless you caught the above post yesterday and took a look I'm afraid you are out of luck.

They delete them so quickly to reduce load on the database server. It had been totally overwhelmed ever since the ATIs entered service here. With the recent move to file-less crunching there might be more headroom again.. but I guess they don't want to touch what finally works.

Message 49087 - Posted: 28 May 2011, 14:58:23 UTC - in response to Message 49032.  

Computation error since app update in April.

I've try all what I could find on this forum:
Update drivers
Restart project
Detached and reattached

Config:

BOINC 6.10.58
Radeon HD3850, Catalyst 11.3
Windows XP SP3 32Bit
Athlon XP 2600+


MilkyWay was running well with opptim app before app update.
I look for a solution since one month, and find nothing!
What is the problem? Is some one have the same problem or THE solution, please?


Error code:

Unhandled Exception Detected...

- Unhandled Exception Record -
Reason: Illegal Instruction (0xc000001d) at address 0x004051F9



The optimized applications are deprecated and won't validate anymore -- there were quite a few news threads about this. We've updated the server code and what we were sending to clients to help reduce server load, so the old optimized applications aren't receiving certain files they need to run.

I don't know if anyone has released any newer optimized applications that run with the new versions of the workunits, but you can always use the ones provided by the server.



Travis, I don't use optimized app any more.
Since the update I use the one from the server.

Here is a complete stderr:

My latest WU's seem to be better behaved with the last one completing without incident and I have 2 more on the go as we speak.

I just noticed I now am getting computation errors on MW@Home. Not sure how to post the info or how toget it any more detailed than it shows in messages. Suffices to say at least ten tasks have went belly up that were going through the night. Not a single MW@Home success on the list. Other projects are having no such problem.

Going to withdraw support for a while until this gets ironed out.

It just happened again and same pattern as the previous pair of WU's. One completed and one failed 'Computation Error'.

Who is writing these things?

Once again >50% of work units are failing due to computation error so am turning off work fetch for Milkyway until such time some kind of attention is paid to this ongoing problem.

The Admins (Travis & Matt) have been and are well aware of the issue and are working to repair the issue.

This might need to be posted elsewhere, but there seems to be no option to start a new thread on my display today.

AGAIN, I'm running Milky Way work units that run, complete and then disappear into thin air. No credit is being issued, I'm running the stock applicaiton. I'm processing on an AMD quad core CPU. The current work units I'm running are listed in my account and the notation at the end says "Not in DB". What does that mean?

This project is becoming increasingly frustrating to run. Work units take many hours to run and then it's like they never existed at all. I'm thinking that if I receive no credit, the project must not be receiving results. If that's the case, something needs to be fixed or changed. If no one is getting the benefit of the CPU time I'm donating, I'm not sure why I'm wasting the electricity....

I think I'll be turning off MW for a while as I'm getting too many 'Error While Computing' and 'Not in DB' WU's. I can't tell what the ratio of good to bad WU's is because they disappear so quickly.

Zen,

on you X4 945 you've got 4 WUs of the "de_separation" type listed. The strange thing is that the website says your app is not in the data base. This is not the WU! WUs finished (either successfully or with some failure) are deleted almost instantaneously here.. which is something that had been used in the past to help the server, but makes troubleshooting increasingly difficult.
In your case I'd try the following:

- Rest the project. You'll probably get a new app, which should then be in the data base again. This one should produce valid results.

- Update your BOINC. 6.4.x is really old and lots of bugs have been fixed since then. You issue could also be a communication problem between an older BOINC client and newer server software.

- Personally I wouldn't want to run separation tasks on any CPU. This app is perfect for GPUs and the ATIs crunch them within minutes instead of hours. And to make matters worse: results become less significant the longer it takes to return them. You could run the n_body app, but sadly I don't think you can choose between the two via the preferences.

The new 0.82 is running fine on my Windows Vista CPU, but N-Body continues to error out within minutes. I wish I could de-select N-Body WUs. Is there any way to do this?
