44.2 Example Workflow in R

Below is a conceptual R workflow demonstrating how to:

1. Load data and define a test subset.

2. Perform computations in parallel for the test subset using the parallel or foreach approach.

3. Measure resource usage (basic approach in R; for deeper HPC environment metrics, rely on the cluster’s job scheduler logs).

4. Extrapolate resource usage.

5. Submit a scaled-up job with new allocations.
