Matrix Product

Analysis and Measurement of Energy Comsumption for Matrix Multiplication.

Dependencies

1. A C++ compiler compatible with C++20
   1. We use g++ but others should work fine
2. PAPI
3. perf, toolkit for performance measurements available in Linux
   1. Requires a compatible CPU w/ RAPL, learn more here
   2. See the manual page w/ man perf
4. OpenMP
   1. Optional, but required in order to execute ./ompproduct.out
5. GNU Make
   1. Again, optional - just for compilation convinience

Usage

make                # builds colproduct and lineproduct
./colproduct.out    # column-based algorithm
./rowproduct.out    # row-based algorithm
./ompproduct.out    # row-based parallel algorithm
make clean          # removes executable file

In case of measuring energy:

# Requires elevated privileges!
# It is also possible to measure the energy consumption of other components
perf stat -e power/energy-cores/ <executable>
