Folding Early Unit End

RobOC · 15 Apr 2006 at 17:22

Hi chaps,

I've been on boinc for a long time with no problems, but having just moved over to give folding a go, I've just had a WU finish early with an error...

Code:

[14:51:44] Step 3453694, time 6907.39 (ps)  LINCS WARNING
[14:51:44] relative constraint deviation after LINCS:
[14:51:44] max 0.458214 (between atoms 750 and 751) rms 1.#QNAN0
[14:51:44] 
[14:51:44] Simulation instability has been encountered. The run has entered a
[14:51:44]   state from which no further progress can be made.
[14:51:44] This may be the correct result of the simulation, however if you
[14:51:44]   often see other project units terminating early like this
[14:51:44]   too, you may wish to check the stability of your computer (issues
[14:51:44]   such as high temperature, overclocking, etc.).
[14:51:44] Going to send back what have done.

[14:51:45] Folding@home Core Shutdown: EARLY_UNIT_END
[14:51:48] CoreStatus = 72 (114)

What could this be down to? I assume overclocking is the likely suspect, but this machine has been stable for ages in boinc. Any ideas?

Thanks guys. I'll see how it goes... though since that was basically my first WU, it doesn't look promising! But yeah it is prime and memtest stable so :confused:

It always was at this overclock, but admit haven't run prime for some time so am running it now. I guess I should really run it until at least morning for a proper test. Will post you the outcome.

Well the prime checked out ok, so I restarted the services and a couple of results have since returned with no problems, so I am keeping an eye on it with my fingers crossed for now
