Problem description:

  • Matrix-Matrix Multiplication Timings (MXM)

A C program which sets up a matrix-matrix multiplication problem A = B * C, and carries it out using it

- Nested FOR I, J, K loops;
- Nested FOR I, K, J loops;
- Nested FOR J, I, K loops;
- Nested FOR J, K, I loops;
- Nested FOR K, I, J loops;
- Nested FOR K, J, I loops;
- the MATMUL FORTRAN90 intrinsic function;

The user is allowed to specify N1, N2, and N3, which define the matrix sizes.

Usage: mxm n1 n2 n3

where:

  • n1 is the number of rows in B.
  • n2 is the number of columns in B and rows in C.
  • n3 is the number of columns in C;

The scope achieved in this project was to implement a parallelized version of the previous explained C code by using OpenMP directives. Pragma regions were correctly placed taking into account concepts already seen at HPC instruction.
