Simlloovia

Simulate transactional systems running on cloud infrastructure

Introduction

Simlloovia is a Python package to simulate transactional systems running on cloud infrastructure.

It uses Malloovia as base to represent the system to be simulated and SimPy as simulation engine.

To use:

• Clone the repository

• From the root of the repository, run this to install in the current environment:

  pip install -e .

• To run a simulation use the simlloovia command. For example, this command runs a simulation from the system described in the test file basic.p, which was generated by Malloovia:

simlloovia --sol-file=tests/sols/basic.p --output-prefix=test --output-dir=. --workload-length=3600 --save-evs=True --quantum=3600

• Check the results in the files test_out.txt and test_reqs.csv.

• The parameters can also be passed with a configuration file using the option --config FILE.

• A dashboard that summarizes the information graphically can be run by installing the dash package:

pip install dash

Run this command:

python dashboard_sim.py

Open the URL http://127.0.0.1:8050/ and select . as Base dir and test as Prefix.

Run simlloovia --help for more options.
