CK ROCProf Tool - Profile CK applications with rocprof-compute

Usage: ck-rocprof <command> [options]

Commands:
  setup                           One-time setup: create Python venv and install dependencies
  run <name> <executable> [args]  Profile executable and save results as <name>
  analyze <name> [block]          Analyze profiling results (default: block 12 - LDS metrics)
  compare <name1> <name2>         Compare two profiling runs
  list                            List available profiling runs
  clean <name>                    Remove a profiling run (use --all for all runs)
  status                          Show current configuration and status
  help                            Show this help message

Examples:
  ck-rocprof setup
  ck-rocprof run baseline ./bin/tile_example_gemm_universal
  ck-rocprof analyze baseline
  ck-rocprof analyze baseline 12
  ck-rocprof compare baseline optimized
  ck-rocprof list
  ck-rocprof clean baseline
  ck-rocprof status

Environment Variables:
  CK_GPU_TARGET        - Override GPU detection (e.g., gfx950, MI300X)
  CK_PROFILE_VENV      - Python venv path (default: \$PROJECT/.ck-rocprof-venv)
  CK_ROCPROF_BIN       - rocprof-compute binary path
  CK_ROCM_REQUIREMENTS - Path to rocprofiler-compute requirements.txt
  CK_WORKLOAD_DIR      - Workload storage directory

Profiling Blocks (use with 'analyze <name> <block>'):
  Block 2:  System Speed-of-Light (SOL)
  Block 6:  Shader Engine (SE) utilization
  Block 7:  L2 Cache metrics
  Block 11: Vector L1D Cache metrics
  Block 12: LDS (Local Data Share) - DEFAULT
  Block 16: Instruction mix statistics
  Block 17: Compute Unit (CU) metrics

LDS Metrics (Block 12):
  - 12.1.3: Bank Conflict Rate (% of peak)
  - 12.2.9: Bank Conflicts/Access (conflicts/access)
  - 12.2.12: Bank Conflict (cycles per kernel)
  - 12.2.17: LDS Data FIFO Full Rate (cycles)

Notes:
  - Workload names must be alphanumeric with hyphens/underscores only
  - Profiling skips roofline analysis (--no-roof) for faster execution
  - Results stored in workloads/<name>/
  - For Docker usage, run via: ck-docker exec ck-rocprof ...
