The CPU and GPU are treated as separate devices that have their own memory spaces. As such, CUDA can be incrementally applied to existing applications. Serial portions of applications are run on the CPU, and parallel portions are offloaded to the GPU. Support heterogeneous computation where applications use both the CPU and GPU. With CUDA C/C++, programmers can focus on the task of parallelization of the algorithms rather than spending time on their implementation. Provide a small set of extensions to standard programming languages, like C, that enable a straightforward implementation of parallel algorithms. It enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU).ĬUDA was developed with several design goals in mind: Introduction ĬUDA ® is a parallel computing platform and programming model invented by NVIDIA ®. var/cache/apt/archives/libcublas-dev_10.2.0.168-1_amd64.The installation instructions for the CUDA Toolkit on Linux. Trying to overwrite '/usr/lib/x86_64-linux-gnu/libcublas_static.a', which is also in package nvidia-cuda-dev 9.1.85-3ubuntu1ĭpkg-deb: error: paste subprocess was killed by signal (Broken pipe)Įrrors were encountered while processing: ]ĭpkg: error processing archive /var/cache/apt/archives/libcublas-dev_10.2.0.168-1_b (-unpack): 253408 files and directories currently installed.) The following additional packages will be installed:ġ upgraded, 0 newly installed, 0 to remove and 145 not upgraded.Īfter this operation, 3,458 kB disk space will be freed. Then I tried to run 'apt -fix-broken install', but got the following error: Reading package lists. Try 'apt -fix-broken install' with no packages (or specify a solution). You might want to run 'apt -fix-broken install' to correct these. I have ubuntu 18.04, and accidentally installed cuda 9.1 to run Tensorflow-gpu, but it seems tensorflow-gpu requires cuda 10.0, so I want to remove cuda first by executing: :~$ sudo apt-get remove -auto-remove nvidia-cuda-toolkit I solved this issue as follow : sudo apt-get purge nvidia*Ĭheck all the options and then it will be uninstalled automatical References: Nvidia uninstallation Solution 2 Go to the line containing reference to Nvidia repo and comment it by appending # in front of the line, for e.g.: #deb / Run the following to delete it: sudo vim /etc/apt/sources.list If you get the problem of broken packages, it has happened since you added repo to the apt/sources.lst. Sudo /usr/local/cuda-11.4/bin/cuda-uninstaller Use it for the uninstallation instead: # To uninstall cuda If you have installed via source files (assuming the default location to be /usr/local) then remove it using: sudo rm -rf /usr/local/cuda*įrom cuda 11.4 onwards, an uninstaller script has been provided. To remove Nvidia drivers: sudo apt-get -purge remove "*nvidia*" To remove cuda toolkit: sudo apt-get -purge remove "*cublas*" "cuda*" "nsight*" If you have installed using apt-get use the following to remove the packages completely from the system: There are two things- nvidia drivers and cuda toolkit- which you may want to remove.
