How to use SSE with AMD!!!!!

[Kendan]

nice find kendan. got the SSE turned on and folding away. But is it ok with stanford to use the beta client in this way? And dont Beta clients expire after a certain point?

It is a quick fix for the problem of Stanford changing things and not making a way to use SSE without the beta client. Personally I think they should have waited to disable SSE till they had a non beta client out for it or made a new flag for turning it on. But they didn't So we have to do what we have to do to get it to work. I do not know if this beta client will expire but they should have an official release before then anyways that will hopefully make it easier to turn on SSE for the rigs that can handle it

how and wheres the reg key to set up the -advmethods -forceasm flags? i'm tired of dinking around with shortcuts

That is just for the service install. Here check it out http://forum.oc-forums.com/vb/showthread.php?s=&threadid=179298

anyone knwo how to change the service installed thing so it runs SSE? i know you overwrite the thing but where does it dothe tags stuff or where in teh reg etc.. i have checked in services and it appears to start up a program called srvany.exe wich probably starts up F@H after it... aany ideas?

just click the link I just posted: http://forum.oc-forums.com/vb/showthread.php?s=&threadid=179298


the tags go in the registry and you still need follow the steps I posted in the first post

I am running the Linux console on a XP1600. I tried to get it to use SSE with no luck. Is there a way to do this? Maybe I am at the wrong forum?

 

[Kendan]

you can use the flags with linux. you can also use them with Wine and linux. I had problems with wine flags and the beta windows client. I suggest using wine with the windows client and just holding out until they get this issue taken care of before trying to make SSE work Using wine should give you a boost in speed. Good luck!!!

I am fairly certain that most of our team is made up of AMD processors, and, if not most, at least a substantial portion. I suspect that other teams have very substantial numbers of AMD cpu's as well.

The question then becomes, why is Stanford making it so difficult to take advantage of our AMD cpu's? At a minimum, they don't seem to care; worst case, they seem to be actively supporting the Intel platform.

Well the stability problem was just with AMD processors. There fix is workable but a pain. hopefully they will have a better solution soon I know you are thinking the Intel connection and the thought has crossed my mind. I am just going to think positively and hope that that is not the case. Until then turn on SSE but make sure your rig is stable using SSE.

Yes. this line tells you SSE is running.

They really aren't. We should consider ourselves LUCKY that they provided a workaround so we can enable SSE again. The problem was/is that T-Breds were/are failing on certain WU's with SSE enabled, but NOT with 3DNow. So, in order for Stanford to get USEABLE results, they needed to (by default) have all AMD CPU's NOT run SSE. Now this problem does not exist with Pally XP's, only with the T-Breds. In a perfect world, the client could differentiate between the 2 and only USE 3DNow on the WU's that are known to crash, or even better, just not send T-Bred CPU's the WU's that they have problems with with SSE enabled. It is very simple to re-enable the SSE.

how soon before i know wether my comp is stable for sse?

There fix sucks!!!

They should have made a new flag not used one that was for something else. That is just my first complaint. they made it so you have to jump thru too many hoops to get it turned back on. I really hope they find a way to make it easier in the future.

Just keep an eye on the log and make sure it is completing workunits and not getting errors and starting over.

Am I missing something here? Hoops? All you need to do (as you know) is download the beta client and delete the gromacs core. That's it. What is so hard about that? Most already have the -forceasm flag if they run gromacs anyway, I know I do on ALL my machines.

Seems to speed things up here on my side.. But i'll keep an eye out for the errors mentioned previously. Folding, folding away!
