# hpca2027-traces

Continuous DynamoRIO / drmemtrace collections of [CRONO](https://github.com/masabahmad/CRONO) graph analytics kernels on **soc-LiveJournal1**, packaged in the same HF/humza layout used by related ifuse / HPCA characterization traces.

Folder names use `*-soc-livejournal` so CRONO LiveJournal bundles stay distinct from other graph inputs and from DC-app traces in this dataset.

## CRONO workloads (graph=soc-LiveJournal1)

| Folder | Binary | Whole fetched instrs | SimPoints (`traces_simp`) |
|---|---|---|---|
| `bfs-soc-livejournal` | `bfs` | ~208M | 10 × 20M |
| `dfs-soc-livejournal` | `dfs` | ~232M | 10 × 20M |
| `bc-soc-livejournal` | `bc` (synthetic) | ~220M | 10 × 20M |
| `pagerank-soc-livejournal` | `pagerank` | ~236M | 10 × 20M |
| `sssp-soc-livejournal` | `sssp` | ~214M | 10 × 20M |
| `community-soc-livejournal` | `community_lock` | ~221M | 10 × 20M |
| `connected_components-soc-livejournal` | `connected_components_lock` | ~221M | 10 × 20M |

Each SimPoint zip is **20M instructions** (10M warmup + 10M ROI). Zip names are ROI segment IDs (e.g. `10.zip`), not a 0..9 index.

## Per-workload layout

```
<workload>/
  command.txt
  events.txt
  trace_clustering_info.json
  fingerprint/
  simpoints/
  traces/whole/...
  traces_simp/{raw,bin,trace/*.zip}
```

## Input graph

- SNAP: [soc-LiveJournal1](https://snap.stanford.edu/data/soc-LiveJournal1.html)
- BC uses CRONO synthetic generation (`bc 1 N DEG`) rather than SNAP text load

## Notes

- Whole-window target ≈ **200M fetched instructions** per workload
- Collected with DynamoRIO drmemtrace offline; SimPoints via Scarab BB fingerprint + SimPoint clustering
- CRONO apps patched for LiveJournal-scale graphs and binary graph load for post-parse tracing
