Probe CPU program's performance

A set of scripts for profiling CPU program performance including：

• FLOP
• Cache access
• DRAM access
• arithmetic intensity
• computation complexity
• ...

requirement

make sure you are working on a physical machine

• perf

sudo apt update
sudo apt install linux-tools-generic

or on WSL2:

wget https://mirrors.edge.kernel.org/pub/linux/kernel/tools/perf/<perf-version>.tar.gz
tar -xzvf perf-<version>.tar.gz
cd perf-<version>/tools/perf
make -j
./perf --version
sudo make install

• python packages: numpy, pandas

example program

compile

g++ -o GeMM -O3 -std=c++11 GeMM.cpp

usage

./GeMM <M> <K> <N> # (M,K) (K,N) -> (M,N)
