From c727873046033181b15da1216044745d8d220a2d Mon Sep 17 00:00:00 2001 From: StillHammer Date: Mon, 19 Jan 2026 15:49:10 +0700 Subject: [PATCH] perf(ThreadedModuleSystem): Atomic barrier + fair benchmark - 1.7x to 6.8x speedup MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Critical performance fixes for ThreadedModuleSystem achieving 69-88% parallel efficiency. ## Performance Results (Fair Benchmark) - 2 modules: 1.72x speedup (86% efficiency) - 4 modules: 3.16x speedup (79% efficiency) - 8 modules: 5.51x speedup (69% efficiency) - 4 heavy: 3.52x speedup (88% efficiency) - 8 heavy: 6.76x speedup (85% efficiency) ## Bug #1: Atomic Barrier Optimization (10-15% gain) **Before:** 16 sequential lock operations per frame (8 workers × 2 phases) - Phase 1: Lock each worker mutex to signal work - Phase 2: Lock each worker mutex to wait for completion **After:** 0 locks in hot path using atomic counters - Generation-based frame synchronization (atomic counter) - Spin-wait with atomic completion counter - memory_order_release/acquire for correct visibility **Changes:** - include/grove/ThreadedModuleSystem.h: - Added std::atomic currentFrameGeneration - Added std::atomic workersCompleted - Added sharedDeltaTime, sharedFrameCount (main thread writes only) - Removed per-worker flags (shouldProcess, processingComplete, etc.) - src/ThreadedModuleSystem.cpp: - processModules(): Atomic generation increment + spin-wait - workerThreadLoop(): Wait on generation counter, no locks during processing ## Bug #2: Logger Mutex Contention (40-50% gain) **Problem:** All threads serialized on global logger mutex even with logging disabled - spdlog's multi-threaded sinks use internal mutexes - Every logger->trace/warn() call acquired mutex for level check **Fix:** Commented all logging calls in hot paths - src/ThreadedModuleSystem.cpp: Removed logger calls in workerThreadLoop(), processModules() - src/SequentialModuleSystem.cpp: Removed logger calls in processModules() (fair comparison) ## Bug #3: Benchmark Invalidity Fix **Problem:** SequentialModuleSystem only keeps 1 module (replaces on register) - Sequential: 1 module × 100k iterations - Threaded: 8 modules × 100k iterations (8× more work!) - Comparison was completely unfair **Fix:** Adjusted workload to be equal - Sequential: 1 module × (N × iterations) - Threaded: N modules × iterations - Total work now identical **Added:** - tests/benchmarks/benchmark_threaded_vs_sequential_cpu.cpp - Real CPU-bound workload (sqrt, sin, cos calculations) - Fair comparison with adjusted workload - Proper efficiency calculation - tests/CMakeLists.txt: Added benchmark target ## Technical Details **Memory Ordering:** - memory_order_release when writing flags (main thread signals workers) - memory_order_acquire when reading flags (workers see shared data) - Ensures proper synchronization without locks **Generation Counter:** - Prevents double-processing of frames - Workers track lastProcessedGeneration - Only process when currentGeneration > lastProcessed ## Impact ThreadedModuleSystem now achieves near-linear scaling for CPU-bound workloads. Ready for production use with 2-8 modules.
