Default Bigadv points changes

After much discussion, we are adjusting the points bonus for bigadv. Bigadv work units have been given a 50% base points bonus over standard SMP; the rationale for this was to compensate for the increased system load, increased memory requirements, and increased upload/download bandwidth requirements. As judged from the high demand for bigadv work units, this has been very much a success, perhaps a little too much so. We would like to continue to offer a bonus for bigadv to offset the above factors, but we don't want demand for bigadv to overwhelm the rest of the project or imbalance the points system.

We are therefore dropping the bigadv base points bonus from 50% to 20%, effective for all work units issued this time onwards.

We very much appreciate the donors who have volunteered to run bigadv work units; these projects add substantially to our scientific capabilities. We do important science with all classes of work units, however, and we want the points system to reflect that. Based on extensive feedback, we are considering renormalizing other parts of the system but have not finalized decisions in that regard.

Thanks again for folding!

New points values, old points values, and unadjusted base values are given in the table below. Deadlines and k-factors remain unchanged.

"Standard points" is what the project would receive for base points if standard SMP. "Old bigadv" is the old bigadv base points (50% bonus). "New bigadv" is the new bigadv base points (20% bonus).

Looks like they are trying to push people towards 12+ core thread folding if they really want the massive ppd. Its a shame really as it means you are stuck running native linux on a machine to get 12+ core support it would seem and to get the big folding bonuses now.

This is going to affect us big-time. Some folks who have spent big money on Bigadv will be disappointed.

I wonder if they are just having a hard time getting Bigadv units ready, or is it simply a case of folders not doing other units enough.

Something had to give. I like this move.

Well this is why my P6800 only gave me 68,000 points over the weekend instead of 105,000. Well this definitely drops the idea of me building a 48-core machine or probably any multi socket machine any time soon.

Its good to seem them trying keep points in line with scientific value to the project. Although it is really frustrating for people trying to build folding machines, or purchase hardware to fold on. Unfortunately it always happens with what Stanford considers to be beta projects, they tend to tweak the points as they go along. I remember the uproar when gpu wu got adjusted as they had caught fire in popularity.

Yeah its a double-edged sword. The current Bigadv point setup dwarfs those with regular machines and regular contributions. You wonder how many folks decided to stop folding with their single ATi gpu or dual-core chip because they looked at the big boys and thought they were not really contributing?

But when you create a points system Stanford should realize by now that folks will spend big money to build around these point schemes.

I wonder if the best method here would have been to simply increase the points for regular gpu and smp projects? No real difference really, except that those who built for 500K or even 1million ppd machines would stll have been able to meet their goals and still have a measure of reward for their money spent?

Well, it'll be back to regular smp units for me once the 2686 gets submitted today ... makes more sense ppd wise (and not as big of a hit when I decide to game for 2-3 hours!). Even folding a 690x series WU won't give me the same ppd as the regular smp's will (significant difference too).

Oh well, at least I'll be upping the number of units I return in one day ... moar science!

I think a big issue (That stanford really didn't forsee) was the willingness of people to go out and build these massive Boxes for BigAdv folding. The demand was stripping out the supply , and other crucial WU's and simulations that they need run were not being met (the ones our GPU's can Crunch).

So it makes sense, I honestly think they didn't see this comming to the level the world brought.
