SPEC CPU 2026 backend-bound top-five traces

This dataset contains the exact whole-trace inputs, canonical per-SimPoint trace bundles, and recovered SimPoint metadata used for the five highest backend-bound results in the corrected SPEC CPU 2026 characterization.

Method

  • —Golden Cove configuration with a 12-way D-cache.
  • —Power modeling disabled.
  • —20 million requested warmup instructions, shortened only at trace start.
  • —10 million measured instructions per SimPoint.
  • —use_fetched_count=1, with one fetch-group tolerance.
  • —Per-input values are ratios of weighted raw TopDown slot counters.
  • —Benchmark values are equal-input macro-averages.

Included workloads

Canonical top-level directories matching the layout used by deepanjalimishra99/ifuse-traces are:

  • —spec2026-749-fotonik3d-r-ref/
  • —spec2026-782-lbm-r-ref/
  • —spec2026-800-pot3d-s-ref/
  • —spec2026-809-cactus-s-ref/
  • —spec2026-822-palm-s-ref/

Each canonical directory contains traces_simp/trace/<simpoint>.zip, fingerprint and SimPoint metadata, validation logs, a release manifest, and checksums. Every ZIP passed CRC and DynamoRIO basic_counts; one representative ZIP per workload also completed a Scarab compatibility run with 20M warmup, 10M measured instructions, and a 12-way D-cache.

The original directories under workloads/ remain as provenance and contain:

  • —the exact official whole-trace ZIP under traces/whole/;
  • —the fingerprint and SimPoint metadata retained with the audited result;
  • —trace_clustering_info.json;
  • —the warmed run summary and raw per-SimPoint result tables;
  • —bundle_manifest.json and SHA256SUMS.

DATASET_MANIFEST.csv records the expected whole-trace size and SHA-256 for every workload. The canonical top-level folders are derived from those exact whole traces; recollection was not required.

Provenance

The source traces were read only through the macOS Finder-mounted Box Drive, relayed to CloudLab, and checkpointed after simulation. The final characterization evidence is in the local deliverable_warmed_20260727 package.
