training is complete. Because digits runs on a Web server, team users can easily share database and network configurations, as well as test and share results. The digits integrates the popular Caffe deep learning framework and supports GPU acceleration using CUDNN.

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

compiler and language improvements for CUDA9 Increased support for C + + 14 with the Cuda 9,NVCC compiler, including new features A generic lambda expression that uses the Auto keyword instead of the parameter type; 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) The CONSTEXPR function can contain fewer restrictions, including var

One, using the GPU module provided in the OPENCV At present, many GPU functions have been provided in OpenCV, and the GPU modules provided by OPENCV can be used to accelerate most image processing. Basic use method, please refer to: http://www.cnblogs.com/dwdxdy/p/3244508.html The advantage of this method is simple, using Gpumat to manage the data transfer between CPU and GPU, and does not need to pay attention to the setting of kernel function call parameter, only need to pay attention to the l

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

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

CUDA 6, CUDAWarp Logically, all threads are parallel. However, from the hardware point of view, not all threads can be executed at the same time. Next we will explain some of the essence of warp.Warps and Thread Blocks Warp is the basic execution unit of SM. A warp contains 32 parallel threads, which are executed in SMIT mode. That is to say, all threads execute the same command, and each thread uses its own data to execute the command. A block can be

Cuda Memory Model: GPU chip: Register, shared memory; Onboard memory: local memory, constant memory, texture memory, texture memory, global memory; Host memory: host memory, pinned memory. Register: extremely low access latency; Basic Unit: register file (32bit/each) Computing power 1.0/1.1 hardware: 8192/Sm; Computing power 1.2/1.3 hardware: 16384/Sm; The register occupied by each thread is limited. Do not assign too many private variables to it dur
