DCPerf Replay-Ready SimPoint Traces
This dataset contains the selected, replay-ready trace archives and SimPoint
metadata needed to run weighted DCPerf experiments immediately. It is the
compact companion to the raw validated release:
harry1332/dcperf-validated-traces-20260709.

trace_clustering_info.json
For a workload-level metric, simulate every archive in
traces_simp/trace/ and combine its result using the matching weight in
simpoints/opt.w. Do not average selected segments uniformly.
videotranscode has one selected segment with weight 1.0. The Tao package
documents its excluded Scarab-undecodable cluster in
trace_clustering_info.json.
The large raw traces/whole trees are intentionally omitted here so that the
replay-ready package remains quick to download. They remain available in the
raw validated dataset.
