I won't talk about the installation of Cuda and Optimus on the theme. I found that some foreigners did not succeed or there were few articles about Kali. After more than one day of repeated installation and testing, this article is the final one, the English version is also released.
Install Cuda and NVIDIA driversThis step is relatively simple. Before installation, we recommend that you edit the/etc/APT/so
/local/cuda', '/usr/lib/nvidia-cuda-toolkit', '/opt/cuda '):
Otherwise the installation program cannot find nvcc
Then install
Python setup. py build
Python setup. py install
After installation, run
Pyrit list_cores
We should be able to see the GPU.

I. Background of the problem
Recently to do a learning sharing report on Cuda, I would like to make an example of using Cuda for image processing in the report, and use shared memory to avoid the global memory not merging, improve image processing performance. But for the CUDA program how to read the

Since the system was upgraded from Ubuntu 14.04 to 16.04, the original Cuda 6.5 could not continue to be used, so Cuda 8.0 was reinstalled. Two, uninstall Cuda 6.5 and drive

Translated from: http://blog.csdn.net/masa_fish/article/details/51882183The installation of CUDA7.5 and CUDA8.0 is a hair-like process. So if you install CUDA8.0, just replace all of the 7.5 below with 8.0.Toss a lot of days, before and after re-installed probably 六、七次 Ubuntu, finally on the Cuda installed, was the pit several times, also took a lot of detours.The first post, also please more advice.EnvironmentNotebook: ThinkPad T450 x86_64Video card:
With the development of graphics cards, GPUs become more and more powerful, and GPU optimizes display images. Computing has surpassed general CPU. Such a powerful chip would be too wasteful if it was just a video card, so NVIDIA launched Cuda to allow the video card to be used for purposes other than Image Rendering and computing (for example, general parallel computing mentioned here ). Cuda is the compute
CUDA and cuda ProgrammingIntroduction to CUDA Libraries
It is the location of the CUDA library. This article briefly introduces cuSPARSE, cuBLAS, cuFFT and cuRAND will introduce OpenACC later.
The cuSPARSE linear algebra library is mainly used for sparse matrices.
CuBLAS is a C
We have installed winxp64 + nvidia driver19 *. * + VS2008 (sp1), and we feel very stuck, so we have been using cuda2.2.
I installed win7 recently and found that the driver compatibility for Versions later than 190 is very good. I installed cuda2.3. I wanted to try VS2010 beta2,
However, I learned from Microsoft's staff that MSBuild still has some bugs, so I cannot use cuda normally and cannot patch me for the moment.
Switch back to VS2008.
When using
When Cuda C is run in the cudart library, the application can be linked to the static library cudart. lib or libcudart. A. The dynamic library cudart. dll or libcudart. So. The Cuda dynamic link library (cudart. dll or libcudart. So) must be included in the installation package of the application.
All running functions of Cuda are prefixed with

CUDA and cuda ProgrammingCUDA SHARED MEMORY
Shared memory has some introductions in previous blog posts. This section focuses on its content. In the global Memory section, Data Alignment and continuity are important topics. When L1 is used, alignment can be ignored, but non-sequential Memory acquisition can still reduce performance. Dependent on the nature of algorithms, in some cases, non-continuous access

Auto lambda = [] (auto A,auto b) {return a * b;};
The return type of the feature is deducted (using the Auto keyword as the return type, as shown in the previous example)

CUDA 5, CUDAGPU Architecture
SM (Streaming Multiprocessors) is a very important part of the GPU architecture. The concurrency of GPU hardware is determined by SM.
Taking the Fermi architecture as an example, it includes the following main components:
CUDA cores
Shared Memory/L1Cache
Register File
Load/Store Units
Special Function Units
Warp Scheduler
Each SM in the GPU is designed to support hundred

There are two ways to write a CUDA program using Python:

Numbapro is no longer recommended. It is split and integrated into accelerate and Numba.

Numba optimizes Python code through the JIT mechanism. Numba can optimize the hardware environment of the Loca
