Summarize your GPU-based heterogeneous Program Development Process

GPU and use them only as the IDs that indicate a computing result, right. Therefore, data dictionary design is also an iterative process. The data dictionary found during development can be optimized as much as possible! The principle of data dictionary design is that the GPU of devices is the service object, and the principle of devices is favored. What are the important points? The design of data dictionaries is very important in heterogeneous development. We do not seek to be in place in one

Experiences of Cuda engineering in

Cuda was introduced a few months ago. At that time, I only learned about how to use it. Now I have read the large-scale parallel processor programming practice book again, the book talks about the first generation of Cuda architecture. Now the GPU has gone through Fermi and is already in the Kepler architecture. I still use the g80 card. It seems that I have to keep up with the times. Today, when we use cuda, we have encountered problems according to our previous ideas. After the solution, the
