In 2026, HPC benchmark reports and dashboards have evolved from simple performance charts to strategic "observability cockpits." These systems do not just track peak FLOPS; they prioritize throughput-per-watt, sustained time-to-solution, and the AI-for-Science lifecycle.

1. Key Performance Indicators (KPIs) for 2026

Modern reports must move beyond the High-Performance Linpack ($R_{max}$) to reflect the heterogeneous nature of contemporary workloads.

Metric Category	Key Metric	Why it Matters in 2026
Sustained Performance	ns/day or years/day	Measures real-world productivity for climate or molecular modeling.
Scaling Efficiency	Parallel Efficiency %	Identifies the exact point where adding nodes results in diminishing returns.
Data Movement	I/O Throughput (GB/s)	Tracks the "Memory Wall" and parallel filesystem (Lustre/GPFS) health.
Energy Efficiency	GFLOPS/Watt	Energy is now a primary first-order constraint for exascale deployments.
AI Integration	Training/Inference Ratio	Measures how well the fabric handles mixed AI and simulation workloads.

2. Specialized Dashboards: The "Observability Cockpit"

HPC administrators now use unified dashboards that correlate hardware telemetry with application-level insights.

• Cluster Health & Heat Maps: Real-time visualization of node-level utilization. Heat maps help identify "hot nodes" or "zombie jobs" that consume power without producing scientific output.
• Self-Benchmarking Dashboards: Tools like Darshan and Altair InsightPro™ allow researchers to track their own job history over time to optimize their resource requests.
• Hybrid Quantum-HPC Dashboards: For 2026, dashboards are beginning to integrate "QCAE" (Quantum Computer-Aided Engineering) metrics, showing the depth of achieved HPC-QC integration.

3. Recommended Tools & Frameworks

To implement these reports, the industry has converged on a few "gold standard" stacks:

• Infrastructure Monitoring: Grafana paired with Prometheus remains the definitive choice for customizable, open-source cluster visualization.
• Application Profiling: HPE CrayPat (Perftools) and NVIDIA Nsight provide deep-dive reports into routine-based hardware counter data and GPU kernel performance.
• Automated Reporting: LinearB and Meegle offer templates for quarterly performance reports, including brand-new metrics for AI velocity and code quality.

4. Interpretation: Turning Data into Strategy

A good report should guide future procurement and policy, not just record the past.

1. Baseline Comparison: Always use the performance on the smallest number of nodes (or a single core) as your baseline. This reveals the "Parallel Overhead" inherent in your software.
2. Harmonic vs. Arithmetic Mean: When combining rate metrics (like ns/day), use the harmonic mean. Using arithmetic means for rates can lead to scientifically incorrect conclusions about average system throughput.
3. Actionable Recommendations: Every report should end with clear next steps, such as: "Upgrade memory bandwidth on Partition B to resolve the identified I/O bottleneck."
