On Ubuntu 20.04, you can simply install NVIDIAs cuda toolkit cuda: sudo apt-get update sudo apt install nvidia-cuda-toolkit There are also install advices for Windows. The packge is around 1GB and it took a while to install… Some minutes later you need to export PATH variables so that it can be found: Find Shared Object … Read more
What’s the relation between nvidia driver, cuda driver and cuda toolkit?
From cuda document http://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#driver-api http://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#versioning-and-compatibility It seems cuda driver is libcuda.so which is included in nvidia driver and used by cuda runtime api Nvidia driver includes driver kernel module and user libraries. Cuda toolkit is an SDK contains compiler, api, libs, docs, etc…
Are cuda kernel calls synchronous or asynchronous
Kernel calls are asynchronous from the point of view of the CPU so if you call 2 kernels in succession the second one will be called without waiting for the first one to finish. It only means that the control returns to the CPU immediately. On the GPU side, if you haven’t specified different streams … Read more
Explanation of CUDA C and C++
CUDA C is a programming language with C syntax. Conceptually it is quite different from C. The problem it is trying to solve is coding multiple (similar) instruction streams for multiple processors. CUDA offers more than Single Instruction Multiple Data (SIMD) vector processing, but data streams >> instruction streams, or there is much less benefit. … Read more
What is the correct version of CUDA for my nvidia driver?
304.xx is a driver that will support CUDA 5 and previous (does not support newer CUDA versions.) If you want to reinstall ubuntu to create a clean setup, the linux getting started guide has all the instructions needed to set up CUDA if that is your intent. I believe you are picking up a 304.xx … Read more
Nvidia graphics driver causing noticeable frame stuttering
… or is there something I can do to fix it other telling people to disable Threaded “Optimization”? Yes. You can create custom “Application Profile” for your game using NVAPI and disable “Threaded Optimization” setting in it. There is a .PDF file on NVIDIA site with some help and code examples regarding NVAPI usage. In … Read more
Why is my GPU slower than CPU when training LSTM/RNN models?
If you use Keras, use CuDNNLSTM in place of LSTM or CuDNNGRU in place of GRU. In my case (2 Tesla M60), I am seeing 10x boost of performance. By the way I am using batch size 128 as suggested by @Alexey Golyshev.
How can I make tensorflow run on a GPU with capability 2.x?
Recent GPU versions of tensorflow require compute capability 3.5 or higher (and use cuDNN to access the GPU. cuDNN also requires a GPU of cc3.0 or higher: cuDNN is supported on Windows, Linux and MacOS systems with Pascal, Kepler, Maxwell, Tegra K1 or Tegra X1 GPUs. Kepler = cc3.x Maxwell = cc5.x Pascal = cc6.x … Read more
How do I run nvidia-smi on Windows?
Nvidia-SMI is stored by default in the following location C:\Windows\System32\DriverStore\FileRepository\nvdm*\nvidia-smi.exe Where nvdm* is a directory that starts with nvdm and has an unknown number of characters after it. Note: Older installs may have it in C:\Program Files\NVIDIA Corporation\NVSMI You can move to that directory and then run nvidia-smi from there. However, the command prompt window … Read more
