World Community Grid Crunch July 2008
As we've just been overtaken by 'UK' and 'TSBT' are also hot on our heals I suppose we better do something about it! It's also one of our worst performing projects where we're currently 116 in the world!
It's several months since we had a 'Crunchathon' so this is as good a time and project to do one on, especially as we're not participating in anything at the moment.
Someone has registered us for the following World Community Grid challenges...
MUSCULAR DYSTROPHY CRUNCH ends 31/7/2008
ALL WCG PROJECTS AND ALL TEAMS ends 1/8/2008
so I suppose we can use them in conjunction with our own crunch.
For this crunch there will be 2 targets...
1 - Regain UK #1 status
2 - Be the first UK team to get 5 million credits, we currently have 4,752,224 - 235,126 to get!
Pros and cons
Pros
It's a very worthwhile project with several subprojects to select...
AfricanClimate@Home
• Please review the system requirements before opting to participate in this project - this is a climate project so if there is work available be prepared to tie up the PC for weeks!
Discovering Dengue Drugs - Together
FightAIDS@Home
Help Conquer Cancer
Human Proteome Folding 2
Nutritious Rice for the World
You can do one, some or all if your PC can take it and there's work available of course!
Cons
Unfortunately there are a couple!
1 - For the credits hogs among us (that includes me!) the credits are, at best, average.
2 - Most of the projects have a large quorum - Nutritious Rice has a quorum of 10, Human Proteome Folding - Phase 2 has 15. This is balanced by having an initial replication of 19. Help Conquer Cancer is 2 and 2. So it can take a few days for your first results to come through.
3 - The project times can be quite long - most are 8 or more hours for this average PC.
This crunchathon that will take us to the end of the month(!) with a break 18 July 2008 00:00 UTC and end 21 July 2008 00:00 UTC for anyone who wants to do the PrimeGrid Lunar Landing Challenge.

Please excuse my density on this, but just what does this mean? :?2 - Most of the projects have a large quorum - Nutritious Rice has a quorum of 10, Human Proteome Folding - Phase 2 has 15. This is balanced by having an initial replication of 19. Help Conquer Cancer is 2 and 2. So it can take a few days for your first results to come through.

Rice is slightly different in that each wu runs 8 hours regardless of machine and although the quorum is 10 (was 14 see below) the wus are not identical to each other
Each result returned by the project contains unique data. We have some additional information in the results that we will use to help us make sure that the very strong majority of results returned contain the correctly computed data.
We are starting out sending 19 results per workunit and validating when 14 are returned. Each workunit will run for about 8 hours on each computer. A computer running this project will generate an additional structure prediction in about 90 seconds of execution time on a average computer.
This means that if you have a really powerful computer, you may generate 1000 structure predictions in 8 hours while a slower computer may only generate 160. We will be awarding credit by averaging the the claimed credit per structure prediction, and then taking that value and awarding the # of structure predictions in a result * the average claimed credit per structure prediction. So in this case if the slower computer had a claimed credit of 80 and the larger computer had a claimed credit of 450, then the average credit per structure prediction would be 0.475. This means that the slower computer would be granted 76 credits and the faster computer would be awarded 475 credits.
The key point though is that all computers should have a estimated time to completion of around 8 hours.

As expected, it's going to take a while for the first results to come through. Once they do I hope we'll see a big increase in output.
Below is a chart to show what is possible. The large peak at the end of last year for for the first WCG challenge. The top day was 32,768. I'm hoping we're going to top that by a large margin!

Guess the 3 gigs a slow computer .
I wish i had a fast one that would get me the 475 credits .
Mind you the 3.2's only asking for 116 :evil:
I get around 130 credits for the 8 hours on this:

My amd 2000xp went to heaven :shock:
But even though it ran at 1600 meg it seemed to be better on most projects.
A good example was milkyway ...
3.2 dual (intel) running xp 64 did a WU in about 8 mins 12 seconds
AMD 2000xp (1600 ish ) on win xp did wu's in 9.12 .
On most projects it held its own against a celeron 2.7
So yeh i'd say AMd's are probs better at crunching :lol:

AMD's seems to be better at projects that are FPU based.
Intels seem to be better at projects that are Integer based.
I know on Milkyway the AMD's (when running linux x64) made the Intel Quad look silly, yet when running Riesel's LLR the Intel was a lot faster.
I think on ABC the Intel was faster than the AMD since ABC is an Integer based project.

Okay guys - I'm stating to panic!
TSBT are only a couple of thousand behind us and they scored 53,000 against our 17,000!
We need to get a rush on or we're dropping to 3rd!

Well there's good news and bad news - unfortunately there's more bad news than good!
Good news - we gained a World place!
Bad news - we lost it again as TSBT overtook us with claymores waving, lifting their kilts and showing us their backsides as they stormed past!
Good news - we're not losing by as much as before as output is slowly rising.
Bad news - we're now 3rd in the UK listing!
This isn't going as well...

I'm sorta hoping that this is like an oil tanker and we'll eventually swing around and start making some headway as, at the moment, we're going backwards!

Well...
We're nearly matching 'UK'. We were just 900 behind them yesterday.
This is pants!
Not because there seems to be a lack of interest in this crunch but the credits are woefully poor. I'm down to a third of what I usually get :(
Reckon I'll stick with it until I get the badge or we get to 5 million - whichever comes sooner and get back to a project with better rewards!
