Celeron = Athlon X2 ??

[vitorgatti]

How can this be possible?
I have a laptop with Celeron M 530 @ 1.73GHz, 1GB RAM running Windows Vista.
And I have a PC with Athlon X2 4800+ @ 2.2GHz, 2GB RAM running Ubuntu Linux 8.10.

Celeron is folding at the same speed is Athlon X2 (1% each hour).

Is this normal?

What project are they both folding ?

What clients do you run ?

To compare performance between various hardware, clients and projects, we use the PPD value (Points per day). Each WU you fold is a worth a certain value (points, which you can get here : http://fah-web.stanford.edu/psummary.html ). For instance, if you fold one WU that is worth 100 points everyday, you'll get 100 PPD ... you'll also get 100 PPD if you fold a WU that is worth 200 points in two days ... and so on. If you don't want to do the maths yourself, you can use a third party utility like Fahmon or Fahspy that will display this information automatically.

Thanks for your reply.

My Ubuntu using Athlon X2 is folding this (copied from terminal):
[02:11:31] Protein: Mini chaperonin
[02:11:31] Writing local files
starting mdrun 'Mini chaperonin'
500000 steps, 1000.0 ps.

And Windows Vista with Celeron is folding this:
[14:13:48] Project: 2611 (Run 0, Clone 870, Gen 80)
[14:13:48]
[14:13:49] Assembly optimizations on if available.
[14:13:49] Entering M.D.
[14:14:10] (Starting from checkpoint)
[14:14:10] Protein: p2611_POPE

Celeron's protein has 250,000 steps, and do 1% each 30 minutes.
Athlon X2's protein has 500,000 steps, and do 1% each 60 minutes.

I concluded then that Celeron and Athlon X2 are folding at the same speed...
Correct me if I'm wrong...!

Or maybe F@H servers detects that my processor is a Celeron and gives easier proteins to fold?

Also you could run a second client on the X2 - at the moment you will only be using half of the available processing power.

Sorry, but 1% == 1% it will take the X2 twice as long to complete the WU because it takes the X2 60 minutes as opposed to 30 minutes for the Celeron to complete 1%. The number of steps is simply a red herring.

That being said, It also matters the specific project. The point values of the project are a reflection of how much work a project entails. so a project that is worth 333 points is supposed to take 1/3 as long to complete as a 1000 point project on the benchmark machine (a 2.8GHz P4 w/o SSE2. So you have to take that into consideration too and your post above does not include that data ...

No, my X2 is already using both cores

And how do I get this data to include here? is it at logs?
It really seems that Celeron is folding at the same speedy X2 is... dunno, I think I'm wrong, but it's what it seems.

Woops probably should've asked rather than just said it

Again, if it takes one of them 2x as long to complete 1% then they will not complete at the same time.

The easiest way is to DL and run FahMon
