# computational-execution-table-generation

## Summary

Systematically execute a suite of computational scripts across multiple software backends, measure wall-clock execution time and resource consumption for each script, and aggregate results into a tabular format for performance comparison and reproducibility verification.

## When to use

When you have a set of gallery or benchmark scripts (e.g., 19 visualization examples) that must be executed against multiple plotting backends (matplotlib, Bokeh, Plotly) and you need to measure and report per-script execution times and total runtime to verify performance claims or establish baseline metrics.

## When NOT to use

- The scripts are designed to run in parallel or have asynchronous/background execution modes where sequential wall-clock timing would not capture true performance.
- Execution time variability is expected to be very high (>50% between runs) without explicit control of system load, in which case you would need multiple runs and statistical analysis (mean, stdev) rather than a single pass.
- The library or backends are still under active development with no stable/reproducible baseline, making time comparison against a fixed table unreliable.

## Inputs

- A directory or manifest listing N computational scripts (e.g., 19 gallery examples)
- A target Python environment with the library and all plotting backends pre-installed
- Expected or baseline execution time table (for validation comparison)

## Outputs

- Tabular result file (CSV or dataframe) with per-script execution times
- Aggregate total execution time across all scripts
- Comparison report: measured vs. reported times

## How to apply

Set up a Python 3.12 environment with the target library (e.g., pyOpenMS-Viz) and all required backends installed. Sequentially execute each script in the suite using a wall-clock timer (Python's `time` module or Unix `time` command), recording execution time for each run. After all scripts complete, aggregate per-script times and compute the total execution time across the suite. Compare measured values against any reported or claimed execution times to validate performance claims. Tabulate results in a structured dataframe with columns matching the expected output schema (Example/Script Name, Time, optional Memory columns) and export to CSV or other tabular format for inspection and archival.

## Related tools

- **Python time module** (Timer for measuring wall-clock execution duration of each script)
- **Pandas** (Data structure (dataframe) for organizing and exporting per-script execution times into tabular result)
- **matplotlib** (One of three plotting backends against which gallery scripts are executed)
- **Bokeh** (One of three plotting backends against which gallery scripts are executed)
- **Plotly** (One of three plotting backends against which gallery scripts are executed)

## Examples

```
import pandas as pd
import time
import subprocess

scripts = ['script_1.py', 'script_2.py', ..., 'script_19.py']
times = []
for script in scripts:
    start = time.time()
    subprocess.run(['python', script], check=True)
    elapsed = time.time() - start
    times.append({'Example': script, 'Time': elapsed})

df = pd.DataFrame(times)
df.to_csv('execution_times.csv', index=False)
print(f"Total time: {df['Time'].sum():.3f} seconds")
```

## Evaluation signals

- All 19 scripts in the suite executed without error and returned a measured execution time for each.
- Aggregate total execution time is computed correctly as the sum of per-script times.
- Measured per-script times match reported times within an acceptable tolerance (e.g., within 5–10% or within one standard deviation if multiple runs are averaged).
- Tabular output schema matches the expected structure (Example, Time, optional Mem columns) and can be imported as a Pandas dataframe or CSV without parsing errors.
- Wall-clock timer is consistent across runs (e.g., sequential re-execution of the same script produces similar times, confirming measurement stability).

## Limitations

- Wall-clock execution time is sensitive to system load, background processes, and hardware state; results may vary by >5% across runs on the same machine without explicit isolation or warm-up.
- The task measures only sequential execution; if scripts can run in parallel or if certain backends cache results, the measured times may not reflect real-world concurrent usage patterns.
- Memory consumption is not explicitly measured in the reported workflow; if memory profiling is required, additional instrumentation (e.g., `memory_profiler` module) would be needed.
- No statistical replication (e.g., n=3 runs per script) is described, so a single measured value has no confidence interval and may be an outlier.
