f@h v4 command line flags

I've been doing some reading and it seem that back in v3 it was recommended that AMD folders add the -forceasm to the client shortcut. It forces the folding client to use SSE vice 3DNow!. And it would give a performance boost. Does that still apply to v4?

Ok all the flags are.....

-config :- Configure user infomation.
-configonly :- Configure user infomation, then exit.
-queueinfo :- Get information on queued work units.
-delete x :- Delete item #x from work queue.
-send x :- Send result #x to server. use x=all to send all results.
-verbosity x :- Sets the output level, from 1 to 9. The default is 3.
-pause :- Pause after finishing & trying to send current unit.
-oneunit :- Exit after completing one unit.
-forceasm :- Force core assembly optimizations to be used if available.
-forceSSE :- Force SSE use (on every unit regardless of success) if available.
-advmethods :- Use new advanced scientific cores and/or work units if available.
-service :- Run in service mode (for programs such as firedaemon).
-local :- Use configuration files from local directory.

For my AMD's I just use -forceSSE and -local on my duallies.
That way I am more likely to get Tinkers which fold faster.
If I had any Intel's I would add the -advmethods flag to try and get DGromacs which again fold faster.
If you want more output in your log file then set the -verbosity flag higher.

Luck..........

Are you using f@h v4?

could you throw a quick tutorial in this to show the new folk how to apply the flags ?










I would, hehe, but dont know how as I just ran the client without flags.

Check that thread about half way down there is a post by me.

Thank you, Sir.

Majic, I noticed in the other thread you said the console version was faster than the GUI version. Significantly faster? Also does the console version leave an icon in the systray? I like to check my progress by hovering the mouse over the icon in the tray.

faster yes so much faster you will notice while sitting there no..
Progress under mouse nope wont do it. console version is cut and dry with no fluff added. its like dos is to windows(GUI)
as for what u will see when min.'d will be just a box on your task bar. but you can use a program like EMIII to hide it and monitor it. Look in the thread above I talk about it there.

How much does the EMIII program take away from system resources? Will the gain of using the console version be worth the added resources of EMIII? Kind of ends justifying the means thing?

i have EMIII running right now in winXP pro using 9346mem and 0 cpu cycles only time it takes 1-2 cycles is if it needs to check something like for a update or something. I am also monitoring 12 cpus on my network using EMIII and i know there are some ppl that use it to monitor more. so i would say yes console with EMIII is much better then GUI(screensaver) version.. and you can hide the console and still see your stats on that w/u

Everyone used to be going out of their way to get Gromacs, now this is not the case?

Did I miss something?

So if you have AMD you should maybe select "GAH only" option?

AMD's fold Tinkers at twice the speed to an Intel.
Stanford has repointed the Tinkers to give you the same Points per Hour per Ghz as a Gromac on an Intel box.
So you get about double the Points per Hour per Ghz on an AMD.
For my AMD boxen it works out at between 1.8 & 2 PHG for Gromacs and between 3 & 3.6 for Tinkers.

If you check with Stanford you will see the timeless protiens are now Gromacs.
So only use the "GAH only" option if your boxen is to slow to finish a work unit inside the time limit.
I think the speed is around 250 Mhz

Is there a way to set the GAH only option using the console client?

I believe that the FaH vs GaH choice is set at the config file level by running FaH4Console -config & you can choose to run GaH preferentially there rather than a command line prompt. Running the console client with the -config flag lets you redo your config file that is created the first time you run the console client.
