Feature request: Which computation is used?

[therealsummoner]

Hi all,

would it be possible for the WUs to show which kind of computing is to be used by the GPU?
I was using a GTX660m for months when i just realized it used "3D" regarding to Windows Task Manager, due to old(broken?) drivers.

I also have a number since a while in the FS List, maybe thats something related? Sorry if distracted.
For example the "1862" here:

Code: Select all

gpu:0:GP107 [GeForce GTX 1050 LP] 1862

Thanx in advance!

Not quite sure what you are asking in the first part of the post. But the GPU folding core always uses OpenCL code that is processed on the shaders in the GPU.

As for the number '1862 ' in the description field of the GPU information, that has been added by the persons entering GPU devices fro the GPUs.txt file. That is just an estimated GFLOPS to make it easier for them to group cards by performance which may be used more in the future for determining assignments

In the log, it does tell you which set of video drivers you are using:

20:18:10:OpenCL Device 0: Platform:0 Device:0 Bus:1 Slot:0 Compute:1.2 Driver:445.87
20:18:10:OpenCL Device 1: Platform:1 Device:0 Bus:4 Slot:0 Compute:1.2 Driver:3004.4

The first is a Nvidia Driver, the second an AMD driver.

If you are using a CPU, there is a line that mentions if you are using SSE2 or AVX-256. (AVX is at least twice as fast)

19:43:41:WU02:FS02:0xa7: SIMD: avx_256

Thanx for your help, it solves actually what i meant.
However, when watching the GPU in Windows Task Manager, it was showing "3D" instead of "Computing" or "CUDA" as busy, which still indicates then that the GPU is using OpenCL?

[Joe_H]

As long as that figure is in the 90% or higher range, yes. Task Manager is quirky at best at showing Compute usage of a GPU versus Rendering for video display. Where it shows the GPU doing computing will depend on which version and patch level of the OS you have and how it reads the data through the drivers from the GPU.

Utilites like GPU-Z that are designed from the beginning to monitor this kind of information from GPUs will be better at displaying it.

[JimboPalmer]

I recommend GPU-Z and it's sensor page. It will show GPU usage, VRAM usage, PCI-E Bus Usage, and Memory Controller usage as well as Power usage both Bus power and Pin power, and some CPU numbers as well.

On the main page it shows how many lanes and what version of PCI-E traffic

If you were watching youtube, have a screensaver on, or run the FAHViewer, you'll see 3D activity in the task manager.
