 Creating a complete and effective Bash script for configuring an HPC cluster's power-saving measures using SLURM involves multiple complex steps that require thorough understanding of both SLURM and the cluster's hardware. However, I can provide you with a simplified example of a Bash script that demonstrates the concept of adjusting SLURM settings for power savings during low utilization periods.
