Benchmarking and Performance Analysis
Evaluate and enhance the performance of HPC systems through comprehensive benchmarking and analysis. From HPL LINPACK and HPCG to STREAM memory bandwidth and MLPerf HPC — the right benchmark suite for procurement, acceptance testing, and ongoing performance management.
HPL LINPACK & TOP500
The TOP500 ranking benchmark since 1993. Measures peak sustained compute via dense LU factorization. World-class systems achieve 60–90% of theoretical peak efficiency.
HPCG — Realistic Performance
Sparse iterative solver benchmark — far more realistic than HPL. Systems score only 3–10% of HPL on HPCG, revealing the true memory-bandwidth reality of scientific workloads.
STREAM — Memory Bandwidth
Measures sustainable memory bandwidth with four vector kernels. Often the best single predictor of real application performance. H100 HBM3 delivers 3,350 GB/s — 37× more than DDR5.
MLPerf HPC
Standardized AI training benchmarks for HPC: CosmoFlow, DeepCAM, OpenCatalyst, and BERT. Measures time-to-train to target accuracy — the definitive standard for AI-capable HPC procurement.
IO500 — Storage Performance
Composite score combining IOR bandwidth and mdtest metadata rate. The standard for ranking HPC storage systems — essential for data-intensive workloads and Lustre acceptance testing.
OSU MPI Benchmarks
Point-to-point latency, bandwidth, and collective operation tests. Essential for InfiniBand fabric validation. InfiniBand achieves ~600 ns latency vs ~5 µs for Ethernet.
Green500 — Energy Efficiency
Ranks systems by GFLOPS per watt alongside TOP500. As power costs dominate HPC TCO, efficiency rankings are critical for modern procurement. Frontier achieves ~52 GFLOPS/W.
Application Benchmarking
Running your actual scientific code on representative inputs — the only benchmark that truly matters for procurement decisions. Measures strong and weak scaling to identify bottlenecks.
