-This document explains how to use the baseline mode functionality that provides a single-shot LLM approach for comparison with the multi-stage pipeline on the new-workflow branch. - -## Overview - -The baseline mode skips the sophisticated multi-stage pipeline (planner → spec_inference → view_inference → inv_inference → repairs) and instead uses a single comprehensive LLM call to generate both specifications and proofs at once. - -## Implementation Architecture - -### Core Components - -#### 1. **BaselineModule** (`src/modules/baseline.py`) -- **Purpose**: Single-shot specification and proof generation -- **Integration**: Inherits from `BaseModule`, uses existing `LLM` and `VEval` infrastructure -- **Features**: - - Comprehensive instruction covering all verification tasks - - Multiple candidate generation (5 per attempt) - - Retry logic with temperature escalation (0.7, 0.8, 0.9) - - Safety checking for immutable functions - - VEval scoring integration - -#### 2. **Main Integration** (`src/main.py`) -- **Environment Detection**: Checks `VERUS_BASELINE_MODE=1` flag -- **Pipeline Bypass**: Skips planner and multi-stage execution -- **Progress Integration**: Uses existing `ProgressLogger` system -- **Output Consistency**: Maintains same file structure as regular pipeline - -#### 3. **Batch Execution** (`run_baseline_bench.py`) -- **Automation**: Processes all `*_todo.rs` files automatically -- **Statistics**: Comprehensive performance tracking and reporting -- **Flexibility**: Multiple configs, timeouts, benchmark limits -- **Error Handling**: Graceful failure management and recovery -

-1. ✅ Before LLM-based syntax repair (line 505) -2. ✅ After compilation error handling (line 579) -3. ✅ Before processing each error type (line 596) -4. ✅ After each repair completes (line 822) -5. ✅ In timeout helper function (line 413) - -CONFIGURATION --------------------------------------------------------------------------------- -Default Settings: - repair_round_timeout: 900 seconds (15 minutes) - -Customization Options: - - Fast iteration: 600s (10 min) - - Default: 900s (15 min) ✓ - - Thorough repair: 1200s (20 min) - - Development: 300s (5 min) - - Disabled: null - -Location: src/configs/config-azure.json - -LOGGING OUTPUT --------------------------------------------------------------------------------- -When timeout occurs, you'll see: - - ⏱️ Repair round timeout reached: 905.23s / 900.00s - 🚨 Repair round timed out before processing PostCondFail - ⏱️ Repair round 3 exceeded timeout: 905.23s / 900.00s - -TESTING --------------------------------------------------------------------------------- -Test Suite: tests/test_repair_round_timeout.py -

Main loop starts repair round, notes start time -2. Calls repair_all() with timeout=900s, start_time=t0 -3. repair_all() defines check_round_timeout(): - - Calculates elapsed = now - t0 - - Returns True if elapsed > 900s -4. Before each major operation, calls check_round_timeout() -5. If timeout detected: - - Log "🚨 Repair round timed out..." - - Return immediately with partial results - - Main loop falls back to best checkpoint - -NEXT STEPS --------------------------------------------------------------------------------- -1. ✅ Implementation complete -2. ✅ Tests passing -3. ✅ Documentation complete -4. 🔄 Monitor production runs for timeout occurrences -5. 🔄 Tune default timeout based on empirical data -6. 🔄 Consider adaptive timeouts in future versions - -ROLLBACK PLAN --------------------------------------------------------------------------------- -If issues arise, disable by setting in config-azure.json: - - "repair_round_timeout": null - -Or remove the parameter entirely. - -================================================================================ - IMPLEMENTATION COMPLETE ✓ -================================================================================ diff --git a/benchmark_summary_20251105_141357.txt b/benchmark_summary_20251105_141357.txt deleted file mode 100644 index 64f9a8bb..00000000 --- a/benchmark_summary_20251105_141357.txt +++ /dev/null @@ -1,25 +0,0 @@ -VERUSAGENT PARALLEL BENCHMARK RUN SUMMARY -================================================================================ -Date: 2025-11-05 14:13:57 -Total: 13 -Success: 13 -Failed: 0 -Timeout: 0 -Error: 0 -Total time: 2535.1s - -DETAILED RESULTS: --------------------------------------------------------------------------------- -atomics_todo SUCCESS 270.7s /home/chuyue/VerusAgent/logs/atomics_todo_20251105_133142.log -bitmap_2_todo SUCCESS 2406.0s /home/chuyue/VerusAgent/logs/bitmap_2_todo_20251105_133142.log -bitmap_todo SUCCESS 844.4s /home/chuyue/VerusAgent/logs/bitmap_todo_20251105_133142.log -bst_map_todo SUCCESS 842.9s /home/chuyue/VerusAgent/logs/bst_map_todo_20251105_133142.log -invariants_todo SUCCESS 77.7s /home/chuyue/VerusAgent/logs/invariants_todo_20251105_133142.log -node_todo SUCCESS 8.1s /home/chuyue/VerusAgent/logs/node_todo_20251105_133142.log -option_todo SUCCESS 76.1s /home/chuyue/VerusAgent/logs/option_todo_20251105_133142.log -rb_type_invariant_todo SUCCESS 2535.1s /home/chuyue/VerusAgent/logs/rb_type_invariant_todo_20251105_133142.log -rwlock_vstd_todo SUCCESS 72.5s /home/chuyue/VerusAgent/logs/rwlock_vstd_todo_20251105_133142.log -set_from_vec_todo SUCCESS 286.5s /home/chuyue/VerusAgent/logs/set_from_vec_todo_20251105_133142.log -transfer_todo SUCCESS 2.6s /home/chuyue/VerusAgent/logs/transfer_todo_20251105_133142.log -treemap_todo SUCCESS 1398.9s /home/chuyue/VerusAgent/logs/treemap_todo_20251105_133142.log -vectors_todo SUCCESS 183.0s /home/chuyue/VerusAgent/logs/vectors_todo_20251105_133145.log diff --git a/check_benchmark_status.sh b/check_benchmark_status.sh deleted file mode 100755 index 32dfc71e..00000000 --- a/check_benchmark_status.sh +++ /dev/null @@ -1,63 +0,0 @@ -#!/bin/bash -# Quick status check for parallel benchmark run - -echo "==========================================" -echo "VERUSAGENT PARALLEL RUN STATUS" -echo "==========================================" -echo - -# Check if running -PROCESS_COUNT=$(ps aux | grep "run_all_benchmarks.py" | grep -v grep | wc -l) -if [ $PROCESS_COUNT -gt 0 ]; then - echo "✅ Status: RUNNING" - echo " Active processes: $PROCESS_COUNT" - echo - - # Show latest output - echo "Latest output (last 10 lines):" - echo "------------------------------------------" - tail -10 run_all_benchmarks.out 2>/dev/null || echo "No output yet" - echo - - # Show log files created - LOG_COUNT=$(ls logs/*_todo_*.log 2>/dev/null | wc -l) - echo "Benchmark logs created: $LOG_COUNT / 13" - if [ $LOG_COUNT -gt 0 ]; then - echo - echo "Most recent logs:" - ls -t logs/*_todo_*.log 2>/dev/null | head -5 | while read log; do - echo " - $(basename $log)" - done - fi - echo - - # Show output directories - OUTPUT_COUNT=$(ls -d output/*_todo 2>/dev/null | wc -l) - echo "Output directories: $OUTPUT_COUNT / 13" - -else - echo "❌ Status: NOT RUNNING" - echo - - # Check if completed - if [ -f run_all_benchmarks.out ]; then - echo "Checking for completion..." - if grep -q "SUMMARY" run_all_benchmarks.out; then - echo "✅ RUN COMPLETED!" - echo - tail -30 run_all_benchmarks.out | grep -A 30 "SUMMARY" - else - echo "Run was stopped or crashed.

multi-stage pipeline on the new-workflow branch. + +## Overview + +The baseline mode skips the sophisticated multi-stage pipeline (planner → spec_inference → view_inference → inv_inference → repairs) and instead uses a single comprehensive LLM call to generate both specifications and proofs at once. + +## Implementation Architecture + +### Core Components + +#### 1. **BaselineModule** (`src/modules/baseline.py`) + +- **Purpose**: Single-shot specification and proof generation +- **Integration**: Inherits from `BaseModule`, uses existing `LLM` and `VEval` infrastructure +- **Features**: + - Comprehensive instruction covering all verification tasks + - Multiple candidate generation (5 per attempt) + - Retry logic with temperature escalation (0.7, 0.8, 0.9) + - Safety checking for immutable functions + - VEval scoring integration + +#### 2. **Main Integration** (`src/main.py`) + +- **Environment Detection**: Checks `VERUS_BASELINE_MODE=1` flag +- **Pipeline Bypass**: Skips planner and multi-stage execution +- **Progress Integration**: Uses existing `ProgressLogger` system +- **Output Consistency**: Maintains same file structure as regular pipeline + +#### 3. **Batch Execution** (`run_baseline_bench.py`) + +- **Automation**: Processes all `*_todo.rs` files automatically +- **Statistics**: Comprehensive performance tracking and reporting +- **Flexibility**: Multiple configs, timeouts, benchmark limits +- **Error Handling**: Graceful failure management and recovery + +## Usage Guide + +### Single Benchmark Execution + +```bash +# Set
