I'm trying to use NVAPI to get GPU information.
But NvAPI fails to return the data on K20c with NVIDIA_DEVICE_NOT_FOUND
I'm using Windows Server 2012 & the display is driven by Onboard chip.
Is NvApi supported on K20 cards?
Please guide
Usually this is due to the wrong driver being loaded (nouveau instead of nvidia - you can check it with lsmod). Other option is to download and install up-to-date drivers from NVidia.
The command nvidia-smi should work at least and report GPU information.
K20c cards are supported by NVML interface provided Nvidia

This Library provides the monitoring & managing information.

When I try to use hardware event-based profiling in VTune (Profiler 2020), I get the error message
Cannot enable Hardware Event-based Sampling due to a problem with the driver (sep*/sepdrv*). Check that the driver is running and the driver group is in the current user group list. See the "Sampling Drivers" help topic for further details.
In the Sampling Drivers section of the use guide it says
Windows* targets: Verify the sampling driver is installed correctly. If required, install the driver.
then asks me to run amplxe-sepreg.exe. This is missing from the bin32 directory. I have reinstalled multiple times.
The amplxe-sepreg.exe application could be found in bin64 folderfor oneAPI beta07 toolkit,
After uninstalling again and installing from the oneAPI package, it worked.
I have developed the gstreamer GPU encoding on Nvidia Jetson Tx2. but now i am
trying for Desktop Nvidia GPU encoding using gstreamer.
I am not able get "omxh264enc" in the listed supported elements using
"gst-inspect-1.0.exe".
so, i want to do hardware encoding on* desktop GPU* using Gstreamer.
Kindly guide me in right direction, or any sample command line or program
for desktop gpu supported encoding.
Note: i am trying on laptop gpu + visual studio 2015

Depends on your GPU hardware. There is nvenc for NVIDIA and msdk for Intel at least. It may be that you have to build these elements yourself as they require proprietary libraries from 3rd party vendors that GStreamer can't redistribute. There is no omx on PC, that one is used for embedded devices primarily.
I have been wanting to work with Vulkan, the new graphics API and have gotten it up and running with no problems on Windows 7. However I can't get Vulkan to work on linux. When I try running any of the LunarG samples, or even my own code, vkEnumeratePhysicalDevices always says that there are no physical devices. Here is my setup:
OS: Ubuntu 16.04 (LTS) [x64]
GPU: Nvidia Geforce GT 730 2GB GDDR5
Driver: NVIDIA Binary driver - version 364.19 from nvidia-364 (open source)
Vulkan SDK: LunarG v1.0.17.0 [ latest version]
I was wondering if maybe there's a file for my GPU that I need to set an environment variable for, but I really don't know. As I said before, this worked on Windows 7 perfectly, but I can't seem to get this to work this the above configuration. I am able to create an instance with the LunarG standard validation layer and the correct extensions, but vkEnumeratePhysicalDevices doesn't find any physical devices. It doesn't give an error, just says it can't find any physical devices. This has really got me stumped and I would really appreciate the help. Thanks!
Depending on your distribution you may have to install the nvidia-utils package. See this issue on my Vulkan repo for details.
If this isn't the case for you check the directories Karl mentioned and check if there is no other ICD (maybe one from Intel) that may cause troubles. If you're on an optimus system with dual GPU you may need to explicitly activate the NVIDIA GPU.
The 730 should work fine on Linux, at least judging from the Linux hardware reports I got on my database like this one.
You shouldn't have to set an environment variable if the driver installed properly.
One way to check for a proper installation is to look for the JSON file that identifies the driver. For example, an nvidia driver will place a file called nvidia_icd.json in /etc/vulkan/icd.d/. /usr/share/vulkan/icd.d/ is another standard, but less common location.
It may also be the case that your GPU does not support Vulkan. Be sure to check your GPU vendor's web pages to confirm support. You may want to download the driver straight from the vendor's site in order to get one that they say has Vulkan support.
And are you sure that using the "Additional Drivers" page is supposed to give you a Vulkan driver?
You can refer to the loader documentation in the docs section at https://vulkan.lunarg.com for more info.
I am kinda new to Android Studio & stuff. So today, I was installing the Android Studio with the SDK Manager. All was going smooth until an error came up which says:
Unable to install Intel HAXM
Your CPU does not support required features (VT-x or SVM).
Unfortunately, your computer does not support hardware accelerated virtualization.
Here are some of your options:
Use a physical device for testing
Develop on a Windows/OSX computer with an Intel processor that
supports VT-x and NX
Develop on a Linux computer that supports VT-x or SVM
Use an Android Virtual Device based on an ARM system image (This
is 10x slower than hardware accelerated virtualization)
I've attached a pic of my system specs. Can someone please throw some light on this issue?
Thanks
It is because you had not intialize virtual technology in your device.You Need to go in BOOT Option before starting WINDOWS OS and enable VT-x from there>
The option of enabling Virtual technology is putted in different option depends on device manufacturer
Edit: Android Studio emulator won't run on Windows with an AMD processor. The error message is kind of misleading, as it suggests the problem is with your CPU. But it is within the troubleshoot message: "Windows/OSX computer with an Intel processor". Basicallly, that means it is not going to work properly in your current setup. Either try installing Linux and running Android Studio on that (which might come with its own issues), using a physical device for testing or use the slow ARM images.
You are using an AMD processor. SVM is AMD technology and VT-x is Intel technology. So you won't be able to get VT-x to run, but SVM might be possible.
As another poster had suggested, virtualization may have been disabled in the BIOS. There may be an option to enable virtualization. It does however seem to happen that virtualization is activated in the BIOS and Android-Studio does not recognize that. I have not figured out how to fix that either.
You could use the emulator with an ARM image, which will be very slow. Alternatively, you could use another emulator that is not integrated into Android-Studio.
I was trying to figure out a way to perform offline compilation of OpenCL kernels without installing Graphics cards. I have installed the SDK's.
Does anyone has any experience with compiling OpenCL Kernels without having the graphics cards installed for both any one of them NVIDIA or AMD.
I had asked a similar question on AMD forums
(http://devgurus.amd.com/message/1284379).
NVIDIA forums for long are in accessible so couldn't get any help from there.
Thanks
AMD has an OpenCL extension for compiling binaries for devices that are not present on the system. The extension is called cl_amd_offline_devices. Pass the property CL_CONTEXT_OFFLINE_DEVICES_AMD when creating a context and all of AMDs supported devices are reported and can be used to create binaries as if they were present on the system.
Check out their OpenCL programming guide at http://developer.amd.com/tools/hc/AMDAPPSDK/assets/AMD_Accelerated_Parallel_Processing_OpenCL_Programming_Guide.pdf for more info
No need to graphic card, you can compile OpenCL programs for CPU too. If you have Intel or AMD CPU this idea works. Download latest OpenCL SDK from corresponding manufacturer website and compile OpenCL program:
Intel OpenCL SDK
AMD APP
