Early unit ends on 4114 units

[Pette Broad]

I only started getting these yesterday in fact I'm only getting sent 41xx units regardless of flags/settings on my Windows system. So far, 2 have already failed with Lincs errors, the first EUE's I've had for a while and the first that either of the 2 machines have had.

Hi!
A LINCS WARNING is nothing to worry about. It's when the WU reaches a point of not being able to continue, and sends back the results.

[PeterA]

Interesting. As soon as I read this tread, I get a 4115 WU. Wish me luck.

[Pette Broad]

No other problems to report, have completed a few 4114's and about 30 41xx's without any further EUE's.

Pete

[sortofageek]

Thus far I have received two 4114s. One completed successfully and the other was an EUE like yours. Don't worry about EUEs if they are occasional.

You also got partial credit for the partial one you did and, although several tried to finish it, nobody yet has been successful.

Hi Pette_Broad (team 33258),
Your WU (P4114 R55 C16 G0) was added to the stats database on 2007-12-04 06:30:11 for 15.49 points of credit.

[James121]

Hmmmmmm
I have a p1429_POLYQBETA-STI GROMACS core running
(actually running under JaneH ID team 48053)
It has been running for weeks and is now 374/500
With a prediction of 10 more days to finish. (on a 1.7 ghz machine)
Will this job ever finish? Is this a realistic length of time for it to take?

[7im]

fahinfo.org is a good site to answer questions like that. Users submit they performance numbers, and then you can search on the averages by various things like Project #, processor type, etc.

[Pette Broad]

Yeah, they take like forever, luckily not too many of them about . Just over 200 hours on an AMD 64 3700+ if memory serves me correctly.

Thank you very much Pete

Noticed that I have folded bunch of 41XX WUs. I do also notice that the points are below par (average of 60-85 PPD -- The highest on 3.2GHz Intel Pentium 4 with 2GB memory).

I sure miss the old forum where I can bring up issue easily.

I've also had a load of these. I've been too busy to check out the PPD but at first glance it seems to be on the low side.

Yes, 110 ppd on a 4103 and that's on a 4400+ with a mere 512mb Ram. Acceptable , but that machine gets 120-125 ppd on 304x units.

Pete

[Pette Broad]

Very High EUE rate on 4113......70% of the ones I've had so far have failed all with LINKS errors. Apart from 4114 which has a 50% failure rate the other WU's in the 41xx series look to be completing O.K.

[Biskquik]

Was getting a little nervous because I haven't had an EUE in a while.

Dunno if this'll help but here's the 4113 log:
