Message 4550 - Posted: 30 Jul 2008, 18:48:56 UTC

I temporarily dropped MW when the big WUS came in, but would like to start running the project again.

But ... I can't find out how long the WUs run because everyones completed WUs get purged before I can look at their run times and credit :(

So, how long does a WU typically take to run on a slow machine (say 2.8 P4), and what credit gets granted?

It would be nice if the WUs didn't get purged so quickly so that I could look at my own progress and that of others. Seems a bit heavy-handed at the moment :(

Cheers,

Al.

There are actually three WU lengths that I have seen.

The shorties, what you were used to.

The short-longs, which take about 8 hours on my P4M 1.8Ghz and pay ~140.

And the long-longs, which take 15-16 hours on my P4M 1.8 and pay 260.

There doesn't seem to be any reason as to how they are distributed, I get all three WU lengths on my boxes (2 P4M's and 2 Q9450's).

Sorry I don't have any machines closer to yours.

I would add that all 3 types progress similarly in that most of the work is done between 0% and 50%. The last 50% goes by very quickly.

I have a 3GHz P4 which does the 3 lengths as follows (approximately)

Short 12 min
Medium 6 hours 5 min
Long 11 hours 51 min

Hope that helps.
Regards
Rod

I think that the rule-of-thumb is that the earlier units (10-series) took a specific amount of time on any given machine (you need to know how much time that was for your processor), the 20-series units took 60 times as long, and the 30-series took 30 times as long. If you know how much time your original units required, then you can approximate that new units' required times.

Replying to myself ...

Thanks for the feedback folks :)

Finished a 'big' WU today. Looked to be taking 18 hours, but sure enough it got to 50% and sped up, ending in 9 hours. Got a nice big 260 credit for it, and given that the host was a 'banger' that's very, very good. The Kredit Kops would be furious ;) Especially as that's more credit than the short WUs used to 'pay' ;)

I've just opened all of my hosts to MW again and filled their caches. It will be interesting to see the mix of WU lengths and credit. I don't generally crunch any project with WUs that take longer than 2.4 hours (having thrown away many KWh of electricity on 'loser' projects in the past!), but I'll give it a go :)

Al.
