Hi weasleyma, I do not have an access to such a exotic HW like mentioned A100 SMX GPU though I can't test CUDA-Z for this kind of modules ;) I might try to update CUDA SDK to a newer version and hope it will work better with your SMX GPU. No promises though. Best regards, AG

Dear Developer.

Hello community, I am using cuda-z to get a baseline benchmark of GPU/vGPU. I am trying to figure out if it is possible to get result in text format so it will be a little easier to write a script and automate benchmark process. Any idea? Thank you. Best, jshen28

Version 0.10.251 of CUDA-Z has a very different appearance than previous releases. However, I prefer the original interface as it more closely resembles GPU-Z and is much more readable. Another issue is that the hyperlinks on the "About" tab are hard to see against the blue moon as shown in the attached screenshot. Is there a way to change the application's theme?

Actually crossing borders seems to be a possibility : https://docs.nvidia.com/cuda/cuda-runtime-api/group__CUDART__INTEROP.html I managed to use JCUDA in my app, I'm retrieving the textures real fast but they do not contain the full image.. It's a promising path but so far I can't see what I did wrong.

You are right. The direction of data transfer does not metter. If you map GPU memory block to CPU memory you will have the abstraction code to translate your calls in backgroud. I do not know if this is the only limiting factor here, but it shurely a significant one. If you use OpenGL, the use of cudaMemcpy() in your code will be most probably useless. OpenGL and CUDA are two non-crossing subsystems, as I know. You have to find something like this in OpenGL itself.

Hello, Using cuda-z I can see that "Device to Host" memory bandwidth is around 2.5 GiB/s on my eGPU Thunderbolt 3 GTX 1080. On an opengl app I am developing, I'm retrieving into CPU memory each frame/texture using http://spout.zeal.co/ My textures are 3840x2160 RGBA, right now it takes around 50 ms to retrieve the texture into client memory. If one compares with the statistics in cuda-z, I should be able to transfer the 31MB in less than 15 ms which is what I need at 60 fps. Spout uses an improved...

Hi! You cannot copy data from CPU memory to GPU memory with normal memcpy() routine directly. The reason for this is that beween CPU and GPU you have a PCIe bus. You have to use a special bus transfer routines like cudaMemcpy(). If you ARE able to use normal memcpy() routine to transfer data to GPU memory, you are clearly dealing with some emulation layer which detects change you made in the CPU memory page and translates them (probably not efficient) to bus transfer calls. Try to use native bus...

Thanks for the quick reply Andriy! That clears things up! I will just pay attention to the DLL version :) It appears when I load an older CUDA SDK (like 6.5), it installs fine, but your program still shows 9.10 as active, and the miner software doesn't seem to know it's there or be able to find the newer version.it's possible that I could drop the DLL's into the mining directory, but I wouldn't know which one's it wanted :) (I could also totally remove the entire video driver package (to get rid...

Hi Greg! You may look at DRIVER DLL as the CUDA DLL version your NVIDIA DRIVER delivered with. In contrary to this the RUNTIME DLL is the DLL CUDA-Z COMPILED WITH and comes from nvidia toolkit version used. DRIVER DLL = 9.10 means your NVIDIA DRIVER supports CUDA (up to) 9.10 RUNTIME DLL = 6.50 means the CUDA-Z APP compiled with compiler version 6.50 As I remember nvidia obsoletes some old CUDA HW with each new driver release. For example CUDA HW < 2.0 does not work since CUDA driver 7.0 (or 7.5)....

Hey all! I'm curious what the difference is between the DRIVER DLL and the RUNTIME DLL as reported by CUDA-Z...? I just loaded the latest Nvidia drivers, and I know they come with CUDA 9, so I get what the DRIVER DLL is (as it shows 9.10), but the RUNTIME shows 6.50...where did that come from? I ask because I have not done any separate CUDA SDK's installs. Do you think this RUNTIME 6.5 ver was installed via this latest Nvidia driver install along with cuda 9.10? After I installed the latest Nvidia...
