Install cuda6.5 + vs2012, the operating system is win8.1 version, first of all the next GPU-Z detected a bit: It can be seen that this video card is a low-end configuration, the key is to look at two: Shaders = 384, also known as Sm, or the number of core/stream processors. The larger the number, the more parallel threads are executed, and the larger the computing workload per unit time. Buswidth = 64bit. The larger the value, the faster the data processing speed. Next let's take a look at the

The actual parameters are different for different machines.* Note 7: The OPENMPI versions supported by configure_openmpi are 1.4.2 and 1.4.3.* Note 8: MKL supports 10.0 or 11.0 series this time. If you are using version 9.0 or earlier, you must add the-oldmkl parameter to configure.* Note 9: The parallelism parameters are

In this paper, the basic concepts of CUDA parallel programming are illustrated by the vector summation operation. The so-called vector summation is the addition of the corresponding element 22 in the two array data, and the result is saved in the third array. As shown in the following:1. CPU-based vector summation:The code is simple:#include the use of the while loop above is somewhat complex, but it is intended to allow the code to run concurrently o

CUDA 3, CUDAPreface The thread organization form is crucial to the program performance. This blog post mainly introduces the thread organization form in the following situations: 2D grid 2D block Thread Index Generally, a matrix is linearly stored in global memory and linear with rows: In kernel, the unique index of a thread is very useful. To determine the index of a thread, we take 2D as an example: Thread and block Indexes Element coordinates
