Matrix C
Example Detailed Explanation:
This program demonstrates a real-world application of high-performance computing (HPC) in C++. It performs matrix multiplication on two randomly generated matrices of size 10000×10000.
The `matrixMultiplication` function takes the two input matrices `A` and `B`, and calculates the product matrix `C`. It uses a nested loop structure to iterate through the rows and columns of the matrices and performs the multiplication operation based on the dot product of corresponding elements from `A` and `B`. The resulting value is then added to the corresponding element in matrix `C`.
In the `main` function, the matrices `A`, `B`, and `C` are declared with a size of 10000×10000. The matrices `A` and `B` are then filled with random values using the `rand` function and the current system time as the seed.
Next, the `matrixMultiplication` function is called with the matrices `A`, `B`, and `C` as arguments. This calculates the product matrix `C`.
Finally, the product matrix `C` is printed to the console. Each element in the matrix is separated by a space, and each row is printed on a new line.
This program showcases best practices in HPC by efficiently performing matrix multiplication using nested loops and avoids redundant or unnecessary computations. It also demonstrates the use of random number generation and well-structured code organization.
