I have been noticing that on one machine the vidio cards are numbered in BOINC the opposite of the way nvidia-settings, gkrellm and nvclock number them. All of the above have the GTX-275 card as the 2nd card and it is physically in the 2nd PCIx slot. Now at one time they were reversed but I had to change them around to keep the 275 cool enough to run. Is there someplace in a config or .xml file that this possibly got set because of their earlier placement? Is there a way to correct it?

The problem seems specific to this machine because my desktop (this machine) does not seem to have this problem. This machine has two GTS-250s in it so it's a bit harder to determine but I believe the OS, device driver, and BOINCmgr all agree that the faster one is in slot1 and called GPU0 or whatever the particular software wants to call the first device. You'll see in this machines startup it lists the GFLOPS of GPU0 at 477 while GPU1 reports 470. The core clock on the GTS-250 in slot one is clocked a bit higher than the GTS-250 in slot two (771 vs 756). gkrellm, nvidia-settings and nvclock all refer to the faster card as the first device. So in this case BOINC seems to match all else.

Below is startup log of my 'c35' machine:

The order is set by the way you insert them in your machine, the drivers you have installed and the library read by BOINC. I think you'll have to reinstall your drivers if you want to see them in the correct order as they are in the machine.

BOINC merely checks for the GPU library, sees if it exists on your system and then shows what - according to that library - is installed and in what order. It doesn't reorder anything.

We're still missing a step someplace...

I reinstalled 195.36.24 drivers right before I posted the results. On that machine nvidia-settings reports GPU 0 as the GTS-250 and GPU 1 as the GTX-275 which corresponds to them being in slot 1 and slot 2.

Boinc still reports:

Thu 03 Jun 2010 05:24:39 PM CDT		NVIDIA GPU 0: GeForce GTX 275 (driver version unknown, CUDA version 3000, compute capability 1.3, 896MB, 691 GFLOPS peak)

I am suspicious of some Xorg setting someplace but it's not in /etc/X11/xorg.conf

Remind me, is there a way to uninstall drivers under Linux? For it may be that you have to get rid of them, before reinstalling that will change this. Some configuration file somewhere that sets the order, that the rest is getting their information from.

Yes, I can uninstall the drivers reboot and let boinc come up saying "GPU missing" stop it, stop the GUI and reinstall the driver. I'll give that a shot tonight. Good idea, thanx.

Skip

PS: There's always "a way" in Linux ;-) It's just a matter of do I know it... LOL
