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 1. Open Cmakelist.txt CMake in the option t

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. An active warp on device has 32 thread

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 Kinectfusion in the ICP using the minimum point to th

During the second part in the reduction summation, the amount of data to be calculated have been greatly reduced when the Second kernel function runs. At this time, it equals the number of threads per block. Given the difference in architecture between the CPU and

I have been trying to read this article before. I have read it today and I have had some gains: 1. After clustering documents by similar terms, Delta is small, which can improve the compression ratio (similarity graph) 1. GPUs generally have hundreds of cores, including shared memory and global memory. Shared Memory is equivalent to the Register speed, and global memory is slow. 2. Search Algorithms on Ordered arrays include binary search and interplation search (Interpolation Search). The av
