Usage

Installation (Amazon Linux 2)

sh ./install.sh

Generate Workload

1. fill workload.toml (or choose one of the pre-configured workloads in the templates folder),
2. then run sh ./workload.sh workload.toml

Run Simulation

sh ./simulate.sh workload.toml

You will find the results in the results sub-folder.

For performance reasons it is recommended to renice these processes to a niceness of -20 whereever possible, e.g. with sudo renice -n -20 -p $(pgrep python3)

Calculate Caching

sh ./caches.sh workload.toml

Run analysis

sh ./analysis.sh workload.toml
