Folding@Home Weekly Team News - 17th March 2006

[Mattus]

Only if you run multiple clients on the same computer. Different computers can share machine IDs, but different clients on the same computer can't.

 

[MajorPart]

That, and Sammael's evil boss costing us 10k+ a day!

I notice that there has been 600 point Gromacs floating about but i've not seen one in about a month maybe longer.. biggest i've had lately are the really fast 364 (1481)

Most of the recent WU are small and have rubbish ppd.

It seem we are also losing members faster than we can gain them, but our average ppd is still pretty good.

Sammael output did hurt us a lot, but i'm sure there is someone out there willing to get thier works/college pc's "hooked up"

Stomp Monster is really needing to be sorted out, but nothing seems to be happenening...

 

[Darryn]

I must be quite lucky, Ive currently got 5x 449 Gromacs, a 364, a 116 and 1 56 pointer, strangely my fastest computer is getting very little but 56pointers, and all the rest are currently getting nice sized units.

 

[MajorPart]

The 449 Gromacs are you getting a good ppd with them?

 

[KillBait]

Been uber super slacker this week (i.e. 0 points), switched over to Seti Beta for a while, it was looking almost like a ghost town in there

 

[BillytheImpaler]

After getting it back up shortly thereater I saw that it had gotten a new WU. It was a weird one:
p1485 p1485_rxnsemi300 166.00 points using FahCore_a0.exe

I had a look around for it wondering what this new core might be. It is called "GROMACS33" on the project summary page but other than that I have no idea what it is. It uses SSE so I hope it's a good one.

I had a look around and found a thread on the official FAH forums talking about it. Apparently it's (currently) a Linux-only Gromacs core that is uber up-to-date with all the shiny new bells and whistles. It's based on the latest Gromacs release, version 3.3. I'll let you know how it goes.

Well I've done a few of these now so I have some data upon which I can report. There are two projects that use this core, 1485 and 1486. I've crunched both now.

1485 is worth 166 pts and is giving me 21 minute frame times. Algebra, Go!: 21 minutes per 1% * 100% = 2100 minutes per WU. 2100 minutes per WU * 60 minutes per hour * 24 hours per day = 1.46 days per WU. 166 points per WU / 1.64 days per WU = 113.8 points per day.

1486 is worth 300 points and is giving me 46 minute frame times. Algebra, Go!: 46 minutes per 1% * 100% = 4600 minutes per WU. 4600 minutes per WU * 60 minutes per hour * 24 hours per day = 3.19 days per WU. 300 points per WU / 3.19 days per WU = 93.9 points per day.

:/
I guess it's not so bad. They could be Tinkers. Remember too that all these times are based on the machine when it is running 4 processes. If I were only running two I would have better ppd in the running WUs. I sacrifice that for better global ppd.

 

[Darryn]

Ive now got 7 out of 8 449point Gromac 2108 wuus, im getting between 77ppd(TBird1400) and 143.5ppd (Xp3500). The only PC that hasnt got a 449 has a 364point Gromac 1481 and im getting 120ppd with a useless old Celeron700.

The only PC that hasnt got a 449 has a 364point Gromac 1481 and im getting 120ppd with a useless old Celeron700.

Ouch that is not so good, i get 447ppd on my laptop from the 1481's...

It is very strange how they allocate the WU's, is there any method in it or is it purely random..?

 

[Darryn]

Im about to get my first 1000point day.... Im almost ready to order my quad core system (dual dual-core opteron), which should be good for a few hundred PPD.

 

[Parsley]

I've just added my laptops Pentium M 2.3ghz and my desktops P4 3.2ghz. I think I have managed to set up the P4 to run 2 cores.

Not sure if that adds a lot of folding power but its being used .

 

[BillytheImpaler]

That is a lot of power. Welcome to the team, Corran. I'm sure you'll be all over next week's stats as you stomp the slackers at the bottom of the list.

Can we help you with anything today?

 

[Parsley]

Just a quick question.

Can I monitor the progess of both of the folds on the P4 using Fahmon?

 

[BillytheImpaler]

Sure can. All you need to do is click in the uper left hand box twice and make two entries. Tell it where each one is located and it'll do the rest. It's just like setting up one client except you're doing it twice.

 

[Parsley]

Sorted. I presume the fact that one entry is orange on the P4 system will sort itself out once I stop using it?

 

[Parsley]

In the process of adding an older Athlon 2800+ now.

 

[BillytheImpaler]

It needs for FAH to run for a while so it can establish some trends. Even then the colors don't carry much weight, they just indicate whether it's running ahead of the prediction or behind it. Keep crunching and it'll sort itself.

 

[Parsley]

Right thats the 3 computers set up and crunching away . I'll ignore the colours then, I only really wanted Fahmon so I could see the % done.

 

[Bennah]

Just to note that the FahMon linky in the setup thread isnt working.

FahMon 2.1.0c Download Guess they have an updated version.

Got FahMon going. Is it ok that, Ive just opened up F@H via services to see if FahMon is working. It says 6% under progress. The little box is orange. Is that a problem? It also says 8% at the end of the progress bar on the right. Should it be displaying the same % ?

 

[Bennah]

Stupid me. Didnt click on my client details to update the progress / info.

All is sorted now. Trying to get more rigs folding soon as possible.

 

[BillytheImpaler]

Thanks for the heads-up. He's changed the FahMon site around quite a bit since the sticky was written. Since version revisions are so frequent I want ahead and changed the download link to go to the downloads page rather than to the file itself.
