Poll: Completion of WU's

Posted: Sat Mar 25, 2006 9:18 pm Post subject: Poll: Completion of WU's

I am presently on my 5th attempt to complete a WU, the four previous attempts failing at 16%, 64%, 96% (sob), and 7%. What are other peoples experience with CPDN, BBC CCE and Seasonal Attribution.

I've had only one failure with BBC CCE. And I've yet to complete a full one, I'm too new!

You won't have completed one yet Jackie if you have had so many in the last few weeks.

Also people who have that many failures are best off ditching the project as you will find it very hard to ever return a complete WU

Everyone gets credit for a CPDN WU as it send a trickle of info to the servers everytime you reach a new time step, this awards you with credit.

So even with all your failed WU's you still get credit due to the trickle up messages

How do I find out how many WU's I have done?
I have credits but it means nothing to me Rolling Eyes

Cheers

I've had two CPDN WUs fail on me (only got to a few percent on each tho) and am on my third one. When this fails (I don't expect it to get to 100%) I'm moving the project onto a different machine which will concentrate more of its time on it.

I liked the sound of the BBC but would never have finished one this year!

Just had a sulphur model fail at 41% having spent over 1700 hours on it. Acoording to the CPDN site I have crunched over the equivalent of 3.5 Hadsm3 WU but in reality I've NEVER had a WU complete successfully. Crying or Very sad

Switching works here fine between 20+ projects

When the CPDN WU crashed I had all both of my other projects (Seti and Rosetta) set to receive no new work and had all Seti and Rosetta WU's suspended so the problem, whatever it is, is certainly not caused by switching between projects.

It may be relevant that if the CPU benchmark tests run whilst I am running CPDN I always find that the CPDN project fails to restart once the test finishes and I have to switch between projects in order to restart CPDN.

CPDN seems 100% reliable here, Only completed 2 WUs but current 2 WUs have run for 1129 and 179 hrs respectively and have 733 and 1927 hrs to go.

Only time I had a problem was recovering from a motherboard failure.

A few WU failures, but every time it was me that caused it in some way (i.e., killing a SAP task at 85% in task manager when trying to back it up, etc).

To run the climate models successfully, the PC needs to be Prime95-stable for at least 24 hours (in some ways CPDN is the harshest test of PC stability there is). It's also sensitive to problems with graphics drivers etc.

Post problems on http://www.climateprediction.net/board/index.php and we'll try to help, a 'messages' tab dump is always useful too.
