How do you want me to send the debug file? Thanks for your time.

After checking the detailed data, it's indeed an NVIDIA driver problem. NVAPI doesn't return information about Teslas at all.
Moreover, due to a bug in addressing, HWiNFO thinks the 2nd adapter is the Tesla, but in fact that information should belong to the 2nd TITAN.
NVIDIA needs to fix this.

Despite that, I think that HWiNFO should display at least the temperature for all GPUs even if not currently properly supported by NVAPI.

This is what Nvidia says:

"Checking with Driver team.

Tesla customers use the nvsmi or nvml for getting the gpu statistics.

Nvapi is more for geforce and quadro. I have asked engg if the nvapi extends to Tesla."

Thanks

yes, 12Gb and 64fp performance is hard to replace for some tasks.
I was very happy they released a 1k$ 6gb card a few months ago, as even current 3gb 780ti is significantly slower for my tasks due to a lot of memory swapping between GPU and system.

12Gb would be even better, but I can not justify 5k$ just yet :)


CUDA6 will introduce Multi-GPU scaling (cublasXT); should allow you to use the GDDR memory of up to 8 cards on one app.
NVidia,

    a new BLAS GPU library that automatically scales performance across up to eight GPUs in a single node, delivering over nine teraflops of double precision performance per node, and supporting larger workloads than ever before (up to 512GB). The re-designed FFT GPU library scales up to 2 GPUs in a single node, allowing larger transform sizes and higher throughput.


FAQ's

HOW TO:
- Opt out of Beta Tests
- Ask for Help
