Using the chStone Benchmark Suite with Hardware Performance Counters and perf

The chStone Benchmark suite is a useful tool for evaluating the performance of embedded processors. It can be used in conjunction with hardware performance counters and the perf tool to measure and compare the performance of different systems.

Hardware Performance Counters

Hardware performance counters are special registers in a processor that are used to count specific events, such as instructions executed, cache misses, or branch mispredictions. These counters can be accessed and used to measure the performance of a system in real-time.

perf Tool

The perf tool is a Linux utility that can be used to collect and analyze data from hardware performance counters. It can be used to profile the performance of a system and identify areas for optimization.

Steps

1. Clone the repository to your local machine

   git clone https://github.com/Adiboy3112/chStone_HPC.git

2. change directory

   cd chstone

3. Run the script

   ./stat.sh

4. Your results will be saved in a folder with name username_result where username is your username.

Note: My results are saved in a folder adiboy_results
