Yesterday hand cheap, put cuda and OPENCV environment variable changed, restart login interface input password prompts error, password must be correct, is not into, is very silent. Various solutions have been tried on the web, such as deleting/tmp and./xauthor in command line mode, or changing the environment variables previously changed, and so on. Finally reinstall the CUDA again, reboot incredibly good.

CUDA, cudagpuDynamic Parallelism So far, all the kernel is called on the host, and the GPU works completely under the control of the CPU. CUDA Dynamic Parallelism allows the GPU kernel to create a call on the device. Dynamic Parallelism makes recursion easier to implement and understand, because the startup configuration can be determined by the thread on the device at runtime, which also reduces data trans

Today, using the thread in Cuda block to modify the hexahedral of two for loops has been wrong.// For (int i= 0;i// { int j= threadidx.x; int i= threadidx.y; // For (int j = 0; j {Is that the incorrect sequence of I and J affects the coordinate position when calculating vertex coordinates: Boxverticescuda[gridindexnumstop].

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 Development Kit + gt520m graphics card. Progr

Oracle VM VirtualBox Downloadubuntu14.04Install the VirtualBox first and then mount the ubuntu14.04 on top. Note To install the enhancements (after starting the virtual machine, select the "Devices" menu, select the "Insert Guest additions CD Images" option.) If you do not see devices, press the right crtl+c), otherwise the screen is not displayed completely.Caffe installation (temporarily not well, encountered problems: After the installation of Cuda

How to quickly and efficiently access the SDK-the overall idea and architecture, and the overall idea architecture of the sdk Question: Many people who develop games probably take over the Channel SDK, UC, dangle, 91, Xiaomi, 360 ...... according to statistics, there are currently no more than 100 channels in the domestic market, and there are also some small cha

I. Concept. 1. Related keywords. CUDA (Compute Unified Device Architecture). GPU English full name graphic processing unit, Chinese translation as "graphics processor." 2. Cuda is a general-purpose parallel computing architecture introduced by NVIDIA, which enables the GPU to solve complex computational problems. It contains the CUDA instruction set architect

Deb file installation, the advantage is not to exit the graphical interface. 1) Download the Deb file from the Cuda website 2) According to the process of the official website. $ sudo dpkg-i cuda-repo-$ sudo apt-get update$ sudo apt-get install Cuda 3) Configure the environment, add the following command to/etc/profile or. BASHRC, save and make it effective with

Chmod + x cuda_6.5.14_linux_64.run ./Cuda_6.5.14_linux_64.run The process went smoothly and ther

MemoryThe performance of kernel can not be explained simply from the execution of Warp. For example, the previous post involved that setting the block dimension to half of the warp size would cause the load efficiency to be lowered, which could not be explained by warp scheduling or parallelism. The root cause is that the way to get global memory is poor.It is well known that the operation of memory occupies a very important position in the language that emphasizes efficiency. Low-latency and Hi

CUDA 8.0 in the function of the call is easy to move people. The following is the VC + + from the online learning of the. cpp file calls the Cuda. cu file in the function method, and the general VC + + function call method basically no difference.The Cuda version used is Cuda 8.0, which is installed by default.1.vs2013
