Matrix Multiplication with Multithreading

This Java program performs matrix multiplication using multithreading. It utilizes threads to multiply matrices concurrently, enhancing the performance for larger matrices.

Files

• Main.java: Contains the main method to generate matrices, perform matrix multiplication, and display the results.
• IndexesOfThreadsData.java: Defines a class to hold thread-related indexes and data.
• MatrixMultiplier.java: Class responsible for matrix multiplication using multithreading.

Classes

Main.java

The Main class handles the execution flow, matrix generation, and result display.

• main(String[] args): Entry point of the program. Generates random matrices, performs matrix multiplication, and prints the resulting matrix.
• generateMatrix(): Generates a random matrix with specified dimensions and random values.
• printMatrix(int[][] matrix): Prints the given matrix to the console.

IndexesOfThreadsData.java

This class defines the data structure to hold thread-related indexes and data used in the matrix multiplication process.

• int row: Holds the row index.
• int column: Holds the column index.
• int data: Holds the computed data during the multiplication.

MatrixMultiplier.java

This class handles matrix multiplication using multithreading.

• MatrixMultiplier(int[][] matrixA, int[][] matrixB): Constructor initializes matrices and sets buffer size based on matrix dimensions.
• multiplyMatrices(): Method to perform matrix multiplication with multithreading and return the resulting matrix.
• generateIndexVector(): Generates an index vector for threads based on matrix dimensions.
• producer(IndexesOfThreadsData args): Performs matrix multiplication for each thread and places the result in the buffer.
