OpenCL Matrix and Vector Multiplication

This repository contains two OpenCL programs for performing matrix-vector multiplication and matrix-matrix multiplication. The programs leverage OpenCL to perform computations on the GPU for improved performance.

Prerequisites

Before compiling and running the programs, ensure that OpenCL development libraries are installed on your system. You can install them using the following command:

sudo apt install ocl-icd-opencl-dev

This will install the necessary OpenCL headers and libraries for compilation.

Files

  • vector_multiply.c: Program to perform vector-matrix multiplication using OpenCL.
  • matrix_multiply.c: Program to perform matrix-matrix multiplication using OpenCL.
  • Makefile: A simple Makefile to compile both programs.

Compilation

To compile the programs, run the following command in the root directory of the project:

make

This will generate two executable files:

  • vector_multiply: The executable for vector-matrix multiplication.
  • matrix_multiply: The executable for matrix-matrix multiplication.

Running the Programs

Once compiled, you can run the executables as follows:

  • Vector-Matrix Multiplication:

    ./vector_multiply

  • Matrix-Matrix Multiplication:

    ./matrix_multiply

Both programs will perform computations on randomly initialized matrices and vectors and print the results.

Cleaning Up

To clean up the compiled executables, run:

make clean

This will remove the vector_multiply and matrix_multiply executables from the directory.
