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.

We all say that GPU Cuda is very Nb-hard, so the next step is to run the program through GPU acceleration. This week, we have been configuring the Cuda environment of opencv. Today we finally ended up failing because the graphics card of the lab machine does not support Cuda... Sorry, a week !!!

Flow: The Cuda stream is much like a CPU thread, and the operations in a cuda stream are sequential and coarse-grained to manage the concurrent execution of multiple processing units.In layman's terms, the flow is used for parallel operations, such as processing the same image, you use a stream to process the left half of the picture, and then the second stream to process the right half of the picture, the

Cuda is very handy for parallel computing, but the interaction between the GPU and the CPU, such as passing parameters, is relatively cumbersome. When writing the Cuda kernel function, there will often be many parameters, to reach 10-20, if the data can be organized in advance of the CPU, such as the use of two-dimensional arrays, which can save a lot of arguments, in the kernel function can use a two-dimen

Compare trial Platform Introduction
After experiencing the outstanding performance of the core I5 2300 in 3D games and multitasking, HD playback and more, today I used my free time to compare my old platform against the core I5 2300 in HD transcoding, and the results were shocking. Good gossip not much to say, first to give their own new and old PC to do an introduction:
