Hi,
Today I checked my running clients (with HFM.net) and found out that one of my CPU clients (Systray version 6.23) stopped working. The strange behavior started at [22:11:35] Completed 284700 out of 499375 steps (57%)

I quit all my running clients (2 v6.23 CPU systray clients and a v6.23 GPU console client) to restart Windows but the b4 core of the "bad" CPU client continued to "work" (=wasting my CPU power for nothing) before I restarted Windows.

Then I checked the FAH-Log and found this message: [11:55:37] Folding@home Core Shutdown: BAD_WORK_UNIT.

Code: Select all

As you can see I restarted the client sometimes, but this should be no problem. Yesterday I only added my passkey to the client and lowered the checkpoint frequency ([18:06:41] + Restarting core (settings changed) ).

Is this error caused by the WU or a random PC error?
My PC specs can be found in this thread: http://foldingforum.org/viewtopic.php?f ... hilit=5765 (page 3)

Thanks for your report. I'm sorry to hear you had trouble with this one. The WU itself wasn't bad, however, as someone else was able to complete it successfully.

What is the exact definition of a bad work unit?
In my case the client itself labeled it as BAD_WORK_UNIT in the log file

Posted: **Fri Oct 22, 2010 7:46 pm**

When I say "bad work unit," I mean a WU which cannot be completed by anyone. In such a case, the mods have the ability to stop the WU from being reassigned. We tend to wait until at least three different folders are unable to complete that WU before marking it bad. If one person can complete it, it isn't a bad WU in the sense we are using here in this forum.

It obviously, however, did prove to be a bad WU for you on that machine.

Thx for the explanation.
If I understand you right you require this BAD_WORK_UNIT message from three different folders for the same project (R,C,G) to mark it as bad WU. It's only because I never had this issue before.
Has somebody finished this WU successfully?
Is it possible to reassign this specific WU to me? I really would like to know if this was a random PC failure or if the error is reproducible on my PC.

There's no way to assign a specific WU to anyone, especially when the WU has already been completed.

There are a variety of possible errors (including BAD_WORK_UNIT) which more or less mean that the analysis has detected data that has been corrupted in some way. The problem here is clearly that "in some way" covers a lot of territory. I'd look seriously for anything that might cause an error in your system including overclocking, heat, outright hardware failures, etc.

From the perspective of the FAH servers, they cannot assume that every PC is stable/reliable/etc. so when there's an error, it has to retry to process the same WU under different conditions. If that succeeds, science marches onward and it's left to the owner of the machine to identify why somebody else could complete that PRCG and you couldn't. FAH has an excellent record of discarding data that contains errors, so science isn't hampered significantly, though fixing any bad node is a good thing (and I'm sure you'll agree).

An extremely rare failure probably isn't worth trying to find and fix. Something that happens regularly is. If you choose to reduce your clock rate or to investigate less critical memory timing (if you've tweaked those) you might want to do that as a safety measure but the bottom line is that it's up to you.

...

No, not necessarily. As Bruce mentioned above, there can be all kinds of reasons why people can't complete a WU. They may get that error message or they may get a different error message. The key isn't the error message. The key is at least three different machine/client setups get that WU and cannot complete it.

Yes, that is what I said above.

The WU itself wasn't bad, however, as someone else was able to complete it successfully.

Thx for your replies. They help me to understand how FAH works.
