# <span style="color:#4078c0">args_to_db</span> - An Argument Optimisation Data Generation Tool

```sh
    pip install args_to_db
```

You want to analyze a (python) script for different arguments/settings? - Argument optimization is becoming more and more important in many application areas. <span style="color:#4078c0">args_to_db</span> is an attempt to generalize and simplify the process of running a programm in different modes or configurations and combining the resulting datasets to allow for further analysis.

## When should I use <span style="color:#4078c0">args_to_db</span>?
You have a programm which is very general in its application, for example a solver framework for linear system of equations. This could look something like

```python
    python solver.py A b [--solver SOLVER] [--preconditioner PRECONDITIONER]
```

Different inputs vary performance of solving methods dramatically. So we want to optimize the solver and preonditiner used for a specific linear system of equations.

## How do I use <span style="color:#4078c0">args_to_db</span>?

So we want to compare different argument configurations. <span style="color:#4078c0">args_to_db</span> takes them in the array form:
```python
    argument_configurations = [['--solver', 'cg'],
                               ['--solver', 'cg', '--preconditioner', 'jacobi'],
                               ['--solver', 'lu']]
```

And then we run all cases via:
```python
    args_to_db.run('solver.py', argument_configurations, threads=3)
```

This spawns upto 3 concurrent processes each running the specified command. As complex applications are mostly reliant on argument optimisations, parallel execution is supported intuitively.

## Data collection
We want to run the test cases individually and not inside a bigger (benchmarking) framework, but spawning different process yields the problem of data collection. Therfore the scripts internally log the results and <span style="color:#4078c0">args_to_db</span> handles combination of those later on.
```python
    args_to_db.add_result('solver_time', 20.3)
    args_to_db.add_result('solver_state', 'converged')

    args_to_db.write_results(__file__, args) # args currently is an argparse object
```
This results in single file outputs of each script. Which are then combined into a single pandas dataframe after all simulations are completed.
