Need Multi-GPU Help......56K!

Have you tried the latest release drivers 177.84?

http://www.nvidia.com/object/cuda_get.html

You are running the latest 6.20 client too right? Once that was released dual-clients were easy as pie.

I am and have been using 177.83. Its worked and not worked--same driver. I seriously doubt its the driver, but a total uninstall/reinstall may be needed (Driver, RT, F@H)

Yes, I am using the 6.20 GPU2 systray---again-its worked and not worked with this version.

I have a cable running from my second card to my TV. I also set the priority to low instead of idle, and put both cards on the same cpu core 3, with -gpu 0 and -gpu 1 flags, I am using the console version...

It was working fine yesterday by plugging in the 2nd monitor, booting up and then pulling the 2nd monitor and putting it back on its pc.

Today I installed the DVI to VGA Dummy and things have been wonky. It works--but not exactly like its supposed to (described above). There's something simple missing....what? I don't know.



I did find this in RT under the "Power User" tab:






The lit up light bulbs would indicate that the device(s) are working, but the Exclamation point would indicate a conflict of some kind.

I clicked the "! above the OK/Apply buttons and the exclamation points went away........!?!? The "!="Find Next Updated Entry".......sorry, I don't have a clue. Sheesh. I tried changing the zero to 1, the 2 to 1--wouldn't take it.

Now I just have to wait until the GPU2 WU completes. This could take years, ya know! But I'm not far from bed, so things may just have to wait until tomorrow. Worst comes to worst---I'll uninstall everything and reinstall.

Ok, well, now its working. Go figure. Not sure if it was clearing the "exclamation" point or if it just needs a few hours to "ramp up" or what.

I don't mind having an issue as much when I finally understand what the "fix" is. Not the case right now though....

Thank You all for helping out! But somehow I doubt this is over.

Just wanted to add another update:

GPU2 just completed another WU and restarted the GUI server. It restarted at ~50%, but ramped up to ~92% in 5-6 steps (%). I've seen it behave this way before and I can definitely live with it. It will be back at 100% before long, until the WU completes and then it will go through this cycle again. Over and over.

That's not what it was doing yesterday though. That's why I've learned to wait and see how it behaves. Yesterday it was just at 50%....period. Or would return to 50% after restarting the GUI.

Anyway, it seems to be working now. But everything will probably fall a part whenever I have to reboot. We'll see....

No doubt some of Ya are tired of this thread/issue, but I'm hoping someone will come along with a fix. Because this is just really strange to me.

The SS below shows that's there is something up with the GPU1 GUI server start/stop. I have no idea what it is, but this is why the problem seems to come and go. But it doesn't come and go--its always there....

This SS shows GPU2 is crankin' along @ 2308PPD and is at 36%, while GPU1 is doing 5386 and is at 86%:



Everything is the same, except GPU1 has made it to 99%:




Now the WU completes on GPU1, the GUI server is STOPPED, the WU is uploaded, a new one is downloaded and the GPU1 GUI server is RESTARTED. At 1% on GPU1--the PPD on GPU2 already start going up:




By 2% on GPU1--GPU2 is back to running ~100%:




It will continue this way until GPU2 completes and when its GUI server restarts--it will go back to 50% production. Then when GPU1 completes and restarts--GPU2 will go back to 100% production.
---------------------------------------------------------------------------------------
EDITing in some SS:

GPU2 completes and restarts....3%--PPD drop like a rock:










---------------------------------------------------------------------------------------
This works out pretty good when GPU1 is only a few % behind GPU2, but not the other way around.

I finally understand the MO here--there is a method to this madness, a rhyme to the reason. Does anybody understand what is causing this and how to fix it?
