WU's and Points

I'm sure there is a thread that explains this, so I apologize for not searching, but how can someone have more points than me, but less work units?
 
There are a variety of WU available, all for different point values. The kind of WU you are assigned by Stanford depend on the type of client you are running and what hardware you are running it on. Take a look here http://fah-web.stanford.edu/psummary.html for the many different work units out in the the wild !


 
I have a rather simple explanation.

I've crunched WU's that were work 20 points. I've also crunched WU's that were worth 1760 points.

You'd have to talk to some of the even older timers how much some WU's were worth back in the beginning. If I remember correctly, there were some worth 1-5 points.

Due to the constantly changing points scale, it's almost impossible to tell who has actually folded more than someone else. For example, there are some people out there that haven't folded for years but have 500k or so points. They also have 20k WU's done too. They were the big producers back towards the beginning when WU's were worth nothing (pointswise) compared to what they are now.

And please, let's not get into the argument/bitchfest about Stanford's points system. We've already done enough of that and the only reason I brought it up to begin with is because it was relevant to the topic at hand.

 
I agree with Smoke.

Look at my score vs. his. I have more WUs, but he has double the points. Just means we have gotten different WUs at different times.



Smoke, when did you join? I thought you were here before me... :confused:
 
In general, the points are benchmarked like so:

--The benchmark machine is a Pentium 4 2.8 GHz running without SSE2 optimizations.
--A specific WU is given a number of points corresponding to 110 points/day on that machine.
--For GPUs, I believe 660ppd is the benchmark for the X1900XTX cards (somebody correct me if I'm wrong here--did they refactor to 550ppd?) running at 3D clocks, or 440ppd at 2D clocks.
--I'm not sure what the benchmark ppd is for the SMP units, but currently it's an enormous bonus, somewhere around 1000-1500ppd.

So some WUs will take longer (and give more points) than others. Also, AMD processors tend to work faster on Amber- and Tinker-core WUs, although both of those cores are not used much any more. Intel CPUs fold faster on GROMACS, which make up the vast majority of WUs currently.
 
At the moment the work units are benched at 1.6 Points per Hour per Ghz on the P4.
When they where benched on the machine before the P4, It was at only 0.8 Points per Hour per Ghz.
It used to be that bonus work-units where worth 2x a standard work-unit, now its only 1.5x a standard one.
Also the newer the CPU, the more likely you will run at a faster speed than the bench mark.

As for the early protiens, look on the EMIII site.
There is a page there which gives the points value of most of the protiens that have been run it the past.

Luck ........... :D

I started with Genome@Home for the [H]orde back before I even joined the forums. Probably by a few months. I just didn't see a reason to join the forums at the time.

For Folding@Home, I started that a bit after the Genome@Home project finished. At the time I had to move out into the boonies and had crap for an internet connection so it was hit and miss on being able to do anything. I did a bit of sneakernetting and running more than one client at a time to keep the computer doing something throughout the day when I wasn't there. Points and WU's didn't come in on a steady basis. At that time I was folding on a T-Bird 1.33@1.57 and a Duron 950 for the majority of my points.

I've mainly been slow and steady on my contributions. I did have a nice bump in points for a while with my P4 2.8 at work running QMDs while running on my XP-m@2.5 along with an XP2400+@2.2 a Duron 1Ghz and a PIII 600. Lost QMDs and the XP2400+ and later lost my XP-m. Had crap for points for about 9 months until I picked up this C2D and you see what I do now with a C2D@3.2, PIII 800, P4 2.8 and I think the PIII 600 on occasion. I haven't been over to my friend's house in a couple of months so I don't know if the PIII 600 is even running anymore.

I need to get over there to check on that PIII, see what I can salvage out of the Duron 1 Ghz and get folding installed on the XP-m since my friend has that and some of my RAM. He owes me money for that and some other stuff so it needs to be folding (and I need the money which is about $500). Maybe I'll get around to doing that tomorrow.

Basically, for a while, you had a lot more machines than me early on which is why you have more WU's done than me. I've also concentrated on bigpackets WUs whenever I could on any machine that I could safely run it on. Currently I'm getting mostly 1760 point WU's with the Linux SMP client. That is where the vast majority of my points are coming from. And I want another C2D system really bad. I need money.
