Dot product and matrix multiplication example

Up to this point, we have learned almost all the important concepts related to basic parallel programming using CUDA. In this section, we will show you how to write CUDA programs for important mathematical operations like dot product and matrix multiplication, which are used in almost all applications. This will make use of all the concepts we saw earlier and help you in writing code for your applications.

Dot product

The dot product between two vectors is an important mathematical operation. It will also explain one important concept in CUDA programming that is called reduction operation. The dot product between two vectors can be defined as follows:

(x1,x1,x3) . (y1,y2,y3) =...
