BFT task distribution model

Simulation model for task pool size calculation.

Description

This model allows to perform experiments of task distribution process in bft environment. Model has 3 parameters:

• number of nodes -n
• number of tasks -v
• precision (number of experiments) -e

Model produces size of node's task pool for chosen precision.

Detailed information about task distribution problem can be found on medium article.

Usage

You can run model inside a docker container or run app manually with go run. Don't forget to turn on gomodules in that case!

Output string 3:67 (1.000) 1(1) means, that for 3 nodes, pool size must be 67 tasks.

Relation between max pool size and obtained pool size is 1.000 - so they equal.

Last column is a number of tries to reduce pool size.

There is also gnuplot file with example from medium article:

$ gnuplot
Terminal type is now 'qt'
gnuplot> load 'results.gp'
