Outputs and File Formats

Main tool log 🗒️

• Filename: cutracer_main_YYYYMMDD_HHMMSS.log
• Contents: Initialization, kernel launch lines (ctx, grid/block sizes, kernel hash), analysis messages.

Per-kernel trace log 🧾

• Filename: kernel_<hash>_iter<idx>_<mangled_name>.log
• Purpose: Detailed per-kernel trace output (e.g., pretty-printed register or memory trace lines) when relevant modes are active.

Histogram CSV 📄

• Filename: kernel_<hash>_iter<idx>_<mangled_name>_hist.csv
• Columns:
  • warp_id (int): Global warp ID.
  • region_id (int): Region ordinal within the warp (clock-to-clock segment).
  • instruction (str): SASS mnemonic (with dot modifiers), extracted from static decoding.
  • count (int): Occurrence count in the region.

Example rows:

warp_id,region_id,instruction,count
0,0,LDG.E.SYS,64
0,0,IMAD.MOV.U32,32

Notes 📝

• Files are written to the traced process's working directory.
• Filenames are deterministic per kernel launch: <hash> is derived from the full mangled name; <idx> is a per-kernel iteration counter.
