Gromacs???

[Vlade]

I am new to folding, and I have a G4 733 MHZ comp, and I was wondering how to get AltiVec working, I have herd that Gromacs supports it, but i have no idea how to use it. Can someone help me? Right now I am using the graphical client.

 

[Vlade]

In process viewer it says I am running this process "FahCore_78.exe", is that the altivec one? if so it doesnt seem very fast at all.

Also, how much faster is the console based verison compared to the graphical one?

 

[Rower_CPU]

78 is the gromacs enabled core.

As far as how much faster it is...I don't think there have been any tests or anything comparing speed.

 

[MrMacMan]

No they don't but if the log file says AltiVec Enabled, then you have it working.

78 is the gromac core, and AltiVec would increase the speed.

My process viewer is showing 65 + not 78. I am running the graphical client (3.25).

 

[jimthorn]

Is there a way to get Graphical Client v3.25 to only receive Gromacs WUs from F@H? I don't know exactly how the client talks to the servers... I mean, does it just ask for a random WU, or is this communication configurable?

Client: Hey, gimme a WU.
Server: Here's a Tinker WU for you.
Client: No, not that one. Gimme a Gromacs one.
Server: Oh, why didn't you say so... Hey you go. And say "thank you".
Client: Thank you.

*ahem* You get the idea.

I have not noticed a great speed increase in the gromacs core wu's I have recieved anyway. It still sucks compared to the pc.

Using the old core, my average was about 20-22 pts/day (3 processors: 1 Dual 1GHz and one 450MHz). Now that they're both running the new core, I'm averaging around 30 pts/day. So there is a good speed increase, but not as much as I'd thought there'd be.

my production has slowed to a crawl. my sole g4 is working on a tinker unit (same rate as always), but my poor g3/266 got a 33-point gromacs WU that, at its current rate, will take 25 days to finish. sadly, the limit for that WU is 14 days. argh.

You still get credit for them, but stanford won't use the results

God damn, stop dragging this into other threads.

Seriously you WILL GET THE POINTS, just it will not help 'them' the people analizing the units you return.

Please, get the mc68k's scripts and you can dump the units!

Recap: you will get points, but it doesn't help the community because the units are too old.

p.s you will get points.

I just watched a Gromacs thingy load onto my PC, but it's not working:

*-------------------------------*
Folding@home Gromacs Core

Preparing to commence simulation
- Looking at optimizations...
- Created dyn

====================

Only that the queue had to be purged after 5 attempts to process data with Gromacs. Something is designed wrong here...

You could just trade with the G4, which is what I do when my G3 gets something too complex. I copy the work folder, queue.dat, and unitinfo.txt to a safe place and move it to the other machine and restart folding. It works everytime.
