1) Questions and Answers : GPU applications : More than one WU per GPU at the same time ? (Message 1081120)

Is the use of Lunatics' Unified Installer only way to run multiple WU per GPU?

I noticed the same.
I'm not using any extra software.
Just SETI@home Enhanced 6.03 windows_intelx86 and SETI@home Enhanced 6.10 windows_intelx86 (cuda_fermi). EVGA precision tells me that GPU's are used (actually GPU usage is higher than usual: ~75% compapred to ~50%). Usually GPU calculations take anywhere between 3 to 14 min, but now 80 to 100 min on GTX-475 (2 units SLI).

I have a related question about 2x vs 3x SLI. I'm currently using 2x GTX470 at 16x PCIe. I'm thinking to add another GPU (with PS upgrade) but it forces me to use 16x 8x 8x PCIe. Only article I could find was [url]http://www.tomshardware.com/forum/296170-33-pcie [/url] at Tom's hardware comparing 2x 16x vs 2x 8x PCIe. It shows minimal loss in 8x mode. I'm not familiar with benchmark they used.

Could someone comment on the data whether this data holds for SETI calculations and whether this data holds for my planned set up of 3x SLI.

All your Cuda machines seems to work as they should, even the one you mentioned above. There's a few errors but nothing out of the ordinary. As far as I can judge you've done a good job in setting up your systems, and can relax, sit back and enjoy the ride.

Very well done.


Thank you but following is what i found in my WU.

This work HAS -9 result_overflow

I went back and looked at some pending results and found a few of these.

Hi, I just added a new cruncher three weeks ago, i7-950 with two EVGA GTX-470s running boinc apps and NO 3rd party apps on windows 7 pro. with the newest nVidia drivers.
I occasionally just stare at boinc tasks screen (as probably all of you do sometimes) and noticed that once in a while cuda calculations finish in a couple of minutes despite the projected time of over 10 min while all other calculations of the same WU series take over 10 min.

Is this what you are talking about?
If so, what can be the cause of this in case of my PC?
All stock apps and newest drivers, it's not even overclocked.
