GPU 2 problems???

I'm thinking this thing is obviously still beta, and I wanted know if anyone else noticed the same thing.

GPU2 beta 11
and win SMP 5.91
Windows 2003 Server R2 x64

If I turn the SMP client on it totally kills my GPU and overall performance.

So I did the logical thing and started playing with config options.

The winsmp priority is set to Idle, and the GPU is set to slightly higher.
If you look in the client.cfg files you see

GPU priority at 96
SMP priority at 0
I have no idea where they came up with these numbers. Must mean something to them.

If you open process explorer (sysinternals), you see that all the cores both the a1 and the a11 are running with a windows priority of 4 (idle). I can change the settings, stop and restart, and the GPU is always running with a priority of 4 (idle).

The CPU lock config option doesn't seem to make a diff either. If I set it to not lock on the CPU, it's still setting affinity to only core 3.

It would be really nice to know of an easy way to force the affinity of the SMP client to cores 0,1,2 and have it be persistent across work units.

I'm going to keep playing with this, but if anyone has any ideas, I'd love to hear them.
 
Windows 2003 = Windows XP so it will take a full core. If you want it to be persistent, build a VM to run the SMP client then assign it to core 0,1,2 while leaving core 3 for the GPU2.

 
To do that you need fahcore_11 beta 7 or higher.

 
speaking of problems...

My new GPU-2 machine cannot pickup a first work unit. After waiting a few hours, I checked on my other GPU boxen and it has the same problem. Anyone else having a problem getting a GPU-2 work unit?
 
4 GPU clients all running full on.
Downloaded 17, 20 , 30 minutes and 2 hours 15 minutes ago.
 
Finally just broke down and put a SLES x64 vmware image up and set it's affinities. At least this way I'll only have to worry about changing it if I restart the VM.
 
There's just something odd about their windows based priority sets. I'm just sticking the VM route for a while. If I get bored, I'll try server 2008 and hyper v and see how it works.

A problem getting and sending and it's been an off and on thing all day. I think if people looked at their log files we probably aren't the only ones;)

 
Stanford have some servers maintenance scheduled yesterday but they didn't foresee the consequences of this maintenance and now, they are a bit overworking to collect the workunits.

 
If they had real servers to start with................:rolleyes:

From the looks of things DO NOT rely on the GPU function of checking your log file. Go in to the program location for more accurate readings.

An example would be do a mouse over on the icon VS reading the log file, many times the info real different.

Luck;)

 
I'm having a problem getting smp and gpu2 to run together, seems every 6 hours I get a bluescreen if I try and run both. I spent the day running prime, memtest, occt etc and no errors.. kinda miffed at this point, would have like to run the smp but have uninstalled it until I can figure out what is going on.

 
What are your temps... usually 6hrs chokes are 1 or 2 things

1. Temps slowly climb causing BSD
2. PSU slowly heats up failing to provide adequate power.

I'm actually fighting something similar, but no BSD, my network connection after about 10hrs just cuts out in vista 64bit...

I'm leaning toward PSU... but won't know until I put this computer on its own ups to see the power draw... its only has a 380w psu with a GTS inside... so could be max'n the power.

Try the 177.41 driver. That solved a similar problem for me with a BSOD 2-3 times a day at similar intervals. This is true if the error is 0x116. Otherwise, follow Sunin's advice.
