I'm searching how I can improve gpu detection for machines which have more than one gpu.
If you have a similar machine, can you please run this application?
This will generate a file named gpu.txt. Can you post file content together with BOINC version. Can you also point out if detection is correct.

Thanks.

WRT reporting 2 GeForce GTX 660 GPU's, that on par with GPUGrid and Einstein:
Coprocessors [2] NVIDIA GeForce GTX 660 (2047MB) driver: 314.22

However, Boinc reads them correctly (Boinc event log):
24/07/2013 21:08:28 | | CUDA: NVIDIA GPU 0: GeForce GTX 660 Ti (driver version 314.22, CUDA version 5.0, compute capability 3.0, 2048MB, 1959MB available, 2985 GFLOPS peak)
24/07/2013 21:08:28 | | CUDA: NVIDIA GPU 1: GeForce GTX 660 (driver version 314.22, CUDA version 5.0, compute capability 3.0, 2048MB, 1968MB available, 1982 GFLOPS peak)
24/07/2013 21:08:28 | | OpenCL: NVIDIA GPU 0: GeForce GTX 660 Ti (driver version 314.22, device version OpenCL 1.1 CUDA, 2048MB, 1959MB available, 2985 GFLOPS peak)
24/07/2013 21:08:28 | | OpenCL: NVIDIA GPU 1: GeForce GTX 660 (driver version 314.22, device version OpenCL 1.1 CUDA, 2048MB, 1968MB available, 1982 GFLOPS peak)

Boinc lists GPU's as CUDA and then OpenCL, so it will list the NVidia GPU's twice.

"GPU compute units: 5" correct for the GTX660, but the GTX660Ti has 7.

PS. I can swap in/out up to 3 discrete GPU's to test if you want.

My i7 x64 Win7 BOINC 7.2.5 :

GPU type: NVIDIA
GPU vendor: NVIDIA Corporation
GPU name: GeForce GTX 680
GPU count: 1

GPU name: AMD Radeon HD 7870/7950/7970 series (Tahiti)

All correct.

I assume this is intended for only windows machines, and then only those with more than one GPU. Unfortunately, I had a couple of machines with both a discrete GPU as well as an Intel HD 4000. Not now though.

These two machines have three physical GPUs. But for several GPU projects, they run multiple tasks per GPU.

Here are mine:

1) GPU type: ATI
GPU vendor: Advanced Micro Devices, Inc.
GPU name: AMD Radeon HD 7870/7950/7970 series (Tahiti)
GPU count: 3
GPU compute units: 32
GPU clock frequency:925

2) GPU type: NVIDIA
GPU vendor: NVIDIA Corporation
GPU name: GeForce GTX 590
GPU count: 3
GPU compute units: 16
GPU clock frequency:1260

I think zombie67's results highlight the problem very well:

WUProp isn't differentiating between the 7870, 7950 and 7970. It knows there are 3 GPU's but doesn't know the exact type. In fact it probably only knows that one of the GPU's is a 7870, 7950 or 7970. The other two could be any type of AMD/ATI.

We also know a GTX590 is a dual core card, but what does the third GPU core belong to? It's an NVidia, but that's all we can tell.

In theory the 'top' GPU is supposed to be reported, and the count just indicates other GPU's of equal or lesser models from the same manufacturer. Back when I was using Fermi's and GF200 cards that held true, however when I've had a GTX660Ti, GTX660 and GTX650TiBoost in the one system, projects reported 3 GTX650TiBoost cards! Perhaps that was broken with a recent Boinc change?

however when I've had a GTX660Ti, GTX660 and GTX650TiBoost in the one system, projects reported 3 GTX650TiBoost cards! Perhaps that was broken with a recent Boinc change?

Local BOINC detects and reports to projects the proper list of GPUs
Only on the web sites of projects the list is simplified to show [3] GTX650TiBoost

Can you check in some sched_request_*.xml for the <coprocs> ... </coprocs> section and (if possible) post that section:

This is from my sched_request_setiathome.berkeley.edu.xml

I modified the application: http://wuprop.boinc-af.org/download/gpu_detect_v2.exe

Can you test it, especially if your machine has 2 or more dissimilar GPU.

Thanks

The Intel HD4000 isn't listed in the gpu text file.
The reported Boost frequency is correct for the reference value of the GTX660Ti, however it's been slightly OC'ed and actually runs at 1202MHz.

I think the issue is that ATI no longer supports CAL in favour of OpenCL. This has caused issues with a number of projects (such as PrimeGrid and Collatz Conjecture, where GPU tasks just crash instantly, as they still expect CAL to be there despite not actually needing it), but it works fine for projects like DistrRTgen that don't have the CAL dependency.

Here's my desktop with a Radeon HD 7770, and a Radeon HD 6550D iGPU on my A8-3870K, Windows 7, BOINC 7.0.64

Found 2 GPUs
ATI/AMD Device 0: AMD Radeon HD 7700 series (Capeverde) (target: 22) (10 multiprocessors @ 1100 MHz)

As you can see, that one is accurate.

_____________

NVIDIA: correct (the integrated NVIDIA GPU is not CUDA capable and is disabled in BIOS, drivers are still installed despite I use only the ATI)

ATI: correct (AMD Radeon HD 6570 @ 800 MHz GPU/1050 MHz DDR3 ; I don't know what is '(target: 18)')
