Oke....after running 3 AP together on my HD6970 it's time to try running the same amount of MB wu's.
I edited the xml file and inserted the '177-files', resceduled some cpu wu's to 'ati-wu' and have a go on it.

After some troubles with 2 hosts, which are now solved, I gonna use the 2 EAH5870 with a i7-2600, INTEL Board(p67)which I can buy (in parts)for €450,00 , could not resist, I bought it inmediatly :)

I see a combination is also possible; 2 MB's together with 1 AP now running.
Had alot of VLAR's.
Think it's better(faster) to cruch them on one of the 6 CPU cores.

heres some data that tells me what the 6970 is going to be capable of.

ran several WU's on my 5850 and 6970 times on the short WU's were 140 seconds for the 5850 and 95 seconds for the 6970

Hard to compaire them, they have Changed Some architectoral changed, or I must be mistaken.

Or is the a later model GPU, probably it is, I guess.....

But a card with a similar amount of Compute Units, cores.....?

Did those WUs validate and grant credit? Can you link to a few? I have not seen times like you're seeing on your 5850 on any of my 5870s (that I have noticed). Average are more like in the 1200 - 2200 second range, I think.

Thats correct Dave.
My 5850 does a regular AR unit in 1700 - 2200 sec running @870/1200 Mhz.

Looking briefly at the average processing rates, Assuming single instance per GPU (I haven't paid attention to what the situation is there on AMD cards), they seem to yield around 140-200 GFlops on average per card with the app you're using, which is impressive & roughly on par with the upper nVidia GTX 2xx series running single instance per GPU, or 1 instance of a 3 instance GTX 480 or 580.

That (IMO) should see some multi AMD card hosts start to creep up in the host rankings, and no doubts will improve as Raistmer continues to polish the apps, and I hear drivers are getting better (?)

@skildude: you need to look at your erroring out.. something going on there.

Hi, but what is a regular AR unit,(in AR range speak), ~0.4AR?
I'm gonna use 2 EAH5870's.
But I'll see, when it's up and running. :)

@#$&*$ crashed the AP-wu after 90 min while rescheduling the VLARs to the CPU!
It's sensetive, so be careful!

Yes Fred.
I call a regular unit a 0.39-0.42 AR unit.
Of course running 2 instances.

Sorry that was on milkyway. I sometimes get distracted. The point is that the 6970 should be 50% faster than the 5850. So far on seti I'm getting similar times from both cards. I'm confident that Raistmer is going to get the most out of the ATI cards

Message 1097435 - Posted: 15 Apr 2011, 10:34:13 UTC

Running r177 HD5xxx with the Catalyst 11.3 (AMD APP SDK 2.4) will cause the executable to use 100% cpu.

Seems to work fine with Cat 11.2 (AMD APP SDK 2.3)

Using HD 6950 btw...

I really need the 11.4 when its out due to some game fixes, so I hope this can be looked into?

It can be looked if it will be reported to AMD on their forums or via their bug tracking system. We don't patch AMD's drivers here, there is lot of work w/o it :P

The beta for 11.4 is only for Win7, Im still on XP :)

So this issue is AMDs fault? Thought maybe they changed something and thus the MB app didn't work properly.

Where do I report problems with the AMD APP? Not even sure what to report. Probably best if the coder of the MB app would report it :)

Message 1097738 - Posted: 16 Apr 2011, 2:52:17 UTC - in response to Message 1097616.  

they are well aware of troubles with the 6970. from the freeze up while watching streaming video, which 11.3 and .4 seem to have fixed. The S@H/video gaming problem(system lock) has yet to be addressed. I assume it may take a few more releases to get things where they should have been to start. I've made mention before that the glitches we've experienced must have been ignored because they showed up the first day for most of us

Message 1099113 - Posted: 20 Apr 2011, 13:50:56 UTC - in response to Message 1097738.  

I noticed mutliple errored WU's all ending at exactly 2988 seconds. I thought this was a bit odd and did a little search. I found that the Flops in the App_info may be a cause of this error. I also found this also my be due to registry entries. Since I've been uninstalling and installing the ATI drivers its a possibility that the old drivers left behind traces on the registry which may have caused the OpenCL to fail to load.

one of the 4 that had identical run times

I don't think it's anything to do with the registry. -177 is "Maximum elapsed time exceeded".

Message 1099158 - Posted: 20 Apr 2011, 16:12:21 UTC - in response to Message 1099157.  

I already ran a GPU memory test - OK
Memtest86 X2 -OK
scandisk - OK
Drivers are updated.

If the OpenCL was attempting to access and use a different version than what was currently onboard then I was assuming this could cause the delay and eventual timeout. I also noticed the excess use of CPU time which again leads me to believe that teh WU is unable to load the OpenCL app.

I hope someoen can enlighten me more on this or at least point out something I missed
