1The first thing to do is to turn on GPU acceleration to install CUDA. To install CUDA, first install Nvidia drive. Ubuntu has its own open source driver, first to disable Nouveau. Note here that the virtual machine cannot install Ubuntu drivers. VMware under the video card is just a simulated video card, if you install Cuda, will be stuck in the Ubuntu graphics interface can not log on the system. So first we need to install a dual system.2Install Ub
Tag: Code screen--line XOR does not have Mina content valueNvidia's graphics card is overclocking-enabled, with tools such as afterburning in Windows.But there is no such thing as a ready-made tool under Linux.But Coolbits's settings are also very simple.Just modify the xorg.conf file to add coolbit and you can overclock it with nvidia-setting.Manual editing is still a hassle, in fact Nvidia provides commands to implement this edit.$sudo nvidia-xconfig -a --cool-bits=24 --allow-empty-initial-con
When compiling the source code with VS compilation OpenCV, the CMake-generated engineering file compiles, and the NVCC fatal:unsupported GPU architecture ' compute_11 ' problem occurs. The reason is that CUDA7.5 does not support older graphics versions, so 1.1,2.0,2.1, such as graphics options, are redundant.
Need to change the configuration of the CMake GUI for the project and remove support for Compute_11

provided by the SDK can be used to test transfer performance from host to Device,device to Host,device to device. Although PCIe has a 3.2g/s theoretical value, it does not actually reach so much. The transmission of Device to Device can reach 89g/s (GTX260), and the theoretical value is 90g/s (GTX260) is about the same. This place is not the same for everyone, the motherboard is not the same, setting the environment is different, not necessarily the same.

Brief introduction
This blog introduces kinectfusion in the ICP algorithm code, code implementation is the PCL Engineering Pcl_gpu_kinfu_large_scale project file ESTIMATE_COMBINED.CU.
The ICP algorithm can greatly improve the computational efficiency by doing parallel computing with the GPU. The objective function in the GPU minimization ICP algorithm

One of the most recent Qualcomm platform projects, where performance is demanding, we use OpenCL to achieve the main functionality, but bottlenecks occur in parts of the CPU that are copied from the GPU memory. Although the OpenCL map API was designed to solve this problem, in some inherent frameworks, map does not avoid all memory copies.Qualcomm has two very useful extensions for OpenCL that can effectively solve this problem:Https://www.khronos.org
. Property bindings (data binding, expression binding). Well, there are properties bindings that are ubiquitous in qml, although there are JS libraries in the H5 that have similar data bindings. But QML is supported in grammar.QML's rendering is also a significant update compared to previous versions. The previous version (Qt4 Qtquick 1.x) was closer to the widget, although it was griphics/view, but the rendering was more of a priority for CPU processing. Of course, in N9 (well, the first system

( Note: This is the cuda-8 version, the current version of the Theano support is not very good, but does not affect the use, it is best to download cuda7.5, I don't bother to reload again, so I use the cuda-8)

We can see on the Internet that AMD's core Math library for GPU has been released. Previously, amd had always felt that his attitude towards gpgpu was not very popular, and he was always slowing down NVIDIA. Now, it seems that he has begun to pay attention to this field, and there are also a lot of actions. From a personal perspective, I prefer nvidia and feel that N cards are indeed much better than a card in development. I wonder if AMD has changed
"Half paper" refers to the small ones that I know can be implemented but can't be done.ArticleThere is no fame or reputation. I am not interested in achieving this. But if you are interested, we can discuss related topics. This article is based on a paper in a finite element conference in libmesh and the limitations of writing a Houdini node to export a fluid point cloud, the purpose is to replace the traditional three-linear difference point cloud data, and the difference can be any point in th

Create a Cuda project on vs2008, create the test. Cu file, copy the following code, compile and execute the code, and clearly see the difference between GPU running matrix multiplication and CPU efficiency. The following result is displayed on my PC. The GPU efficiency of matrix multiplication is improved by about an order of magnitude (relative to the CPU). The development environment is vs2008 + cuda5.x D
Accelerating computer vision algorithms using opencl on the mobile GPU
March 12th, 2013
Abstract:
Recently, general-purpose computing on graphics processing units (gpgpu) has been enabled on mobile devices thanks to the emerging heterogeneous programming models such as opencl. the capability of gpgpu on mobile devices opens a new era for mobile computing and can enable computationally demaning computer vision algorithms on mobile devices. as a case
As the project needs to upgrade the Android 2.3 system, it is necessary to analyze the feasibility of JIT.

GPU deep mining (III): OpenGL frame buffer object 201Author: Rob 'phantom '; Jones Translator: 文 Updated: 2007/6/15 IntroductionIn the previous article OpenGL framebuffer object 101, I introduced some basic FBO applications. The article mainly introduced how to generate a FBO, how to render data to a single texture and apply the texture elsewhere. However, FBO extensions are not the only method to achieve this. In the previous article, we mainly talke
