• Makefile:

  Builds all C sources.

=======

• mult_orig.c:

  Original version of matrix multiplication.

• mult_seq.c:

  Sequential version of matrix multiplication (with time measuring).

• mult_seq_prio.c:

  Sequential version with realtime priority (results not used in report).

• mult_par_v1.c:

  Parallel version of matrix multiplication. Parallelization: inner loop (k)

• mult_par_v2.c:

  Parallel version of matrix multiplication. Parallelization: middle loop (j)

• mult_par_v3.c:

  Parallel version of matrix multiplication. Parallelization: outer loop (i)

=======

• measure_par.py:

  Measure parallel version repeatedly and save stats in file.

• measure_seq.py:

  Measure sequential version repeatedly output stats.

=======

• showresult*.dem:

  Gnuplot scripts to generate diagrams.

• measure_all.sh:

  Bash script to execute test series with different program versions.

• Compile executables: make
• Edit mult_measure_par.py to set matrix size, iterations, number of threads.
• Measurement: ./mult_measure_par.py .
• Edit showresult*.dem to adjust.
• Generate diagram e.g.: gnuplot showresult_cmp_versions.dem.
• Generate all diagrams at once ./produce_diagrams.sh

Generate stress on OS with this tool:

stress --cpu 8 --vm 4 --timeout 200s

(was used compare a normal with a high priorized version (mult_seq_prio.c))
