Sparse Matrices · GitHub license mac version

The motivation behind this project is to understand the fundamentals behind the time and space complexity of algebraic routines on sparse matrices, given different conditions. A major part of this project is understanding the im- portance of preconditioning, where the use of different preconditioners, which are the different sparse matrix representations; as well as multi-threading and parallelism, can lead to a significant reduction routine computation times.

Information regarding OpenMP multi-threading and the different sparse matrix representations have been covered in detail in the report.

Installation

Use the provided Makefile to compile the program which will create an executable matrix program.

make install

Usage

The program must be run with parameters. There are a few optional and required parameters. View the CLA usage below.

matrix {routines} [options] -f matrix1 [matrix2]

Routines:

  • --sm scalar perform scalar multiplcation with value scalar
  • --tr compute the matrix trace value
  • --ad perform matrix addition on two matrices, matrix2 must be specified
  • --ts transpose the given matrix
  • --mm perform matrix multiplication on two matrices, matrix2 must be specified

Options:

  • -t threads specify the number of execution threads to use
  • -l if present, results will be logged to an output file
  • -s if present, results will not contain the matrix data

This program has been tested on Mac environments.
