From e28f0da4f14e4cbb7ac6208bf8625eb4d10c901f Mon Sep 17 00:00:00 2001 From: Ammar Date: Sat, 8 Nov 2025 21:27:15 +0000 Subject: [PATCH 1/5] =?UTF-8?q?=F0=9F=A4=96=20feat:=20add=20hysteresis-bas?= =?UTF-8?q?ed=20adaptive=20concurrency=20for=20terminal-bench?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements adaptive concurrency control for terminal-bench using a burst-and-resume pattern that automatically adjusts parallelism based on system load average. ## Key Features - **Hysteresis-based adjustment**: Double concurrency when load < threshold, halve when load > threshold - **Burst-and-resume pattern**: Runs terminal-bench in bursts, using native resume capability to skip completed tasks between bursts - **Clean container lifecycle**: No mid-task interruption, each burst completes naturally before adjusting - **Configurable parameters**: Max concurrency, load threshold, check interval ## Implementation - `benchmarks/terminal_bench/adaptive_bench.py`: Main wrapper implementing burst-and-resume logic with load monitoring - `benchmarks/terminal_bench/adaptive_bench_test.py`: Unit tests for adaptive logic - `Makefile`: New `benchmark-terminal-adaptive` target - Documentation updates in `benchmarks/terminal_bench/README.md` ## Usage ```bash # Start with concurrency=1, scale up to 16 based on load TB_MAX_CONCURRENT=16 make benchmark-terminal-adaptive # Conservative: max 8, higher load threshold TB_MAX_CONCURRENT=8 TB_LOAD_THRESHOLD=2.0 make benchmark-terminal-adaptive # Sample 5 tasks with adaptive concurrency TB_SAMPLE_SIZE=5 TB_MAX_CONCURRENT=8 make benchmark-terminal-adaptive ``` ## How It Works 1. Start with concurrency=1 2. Run terminal-bench burst with current concurrency 3. After burst completes, check 1-minute load average 4. Adjust concurrency: double if load < threshold, halve if load > threshold 5. Update tb.lock with new concurrency 6. Resume run (skips completed tasks automatically) 7. Repeat until all tasks complete ## Tradeoffs - ✅ Automatically finds optimal concurrency for hardware - ✅ Prevents system overload - ✅ Uses terminal-bench native features (resume, tb.lock) - ⚠️ Burst overhead ~2-5s (acceptable for 6+ minute avg task duration) - ⚠️ Modifies tb.lock (semi-internal format, but stable) ## Design Rationale Research showed terminal-bench uses fixed-size ThreadPoolExecutor that cannot be resized mid-run. Kill-and-restart approach would interrupt Docker containers mid-task. Burst-and-resume leverages terminal-bench's built-in resume capability for clean checkpointing and task skipping. _Generated with `cmux`_ --- Makefile | 41 ++- benchmarks/terminal_bench/README.md | 61 ++++ benchmarks/terminal_bench/adaptive_bench.py | 275 ++++++++++++++++++ .../terminal_bench/adaptive_bench_test.py | 273 +++++++++++++++++ 4 files changed, 649 insertions(+), 1 deletion(-) create mode 100755 benchmarks/terminal_bench/adaptive_bench.py create mode 100644 benchmarks/terminal_bench/adaptive_bench_test.py diff --git a/Makefile b/Makefile index a27559132..9a860e633 100644 --- a/Makefile +++ b/Makefile @@ -39,7 +39,7 @@ include fmt.mk .PHONY: dist dist-mac dist-win dist-linux .PHONY: docs docs-build docs-watch .PHONY: storybook storybook-build test-storybook chromatic -.PHONY: benchmark-terminal +.PHONY: benchmark-terminal benchmark-terminal-adaptive .PHONY: ensure-deps .PHONY: check-eager-imports check-bundle-size check-startup @@ -330,6 +330,45 @@ benchmark-terminal: ## Run Terminal-Bench with the cmux agent (use TB_DATASET/TB $$TASK_ID_FLAGS \ $${TB_ARGS} +.PHONY: benchmark-terminal-adaptive +benchmark-terminal-adaptive: ## Run Terminal-Bench with adaptive concurrency (use TB_MAX_CONCURRENT/TB_LOAD_THRESHOLD/TB_CHECK_INTERVAL) + @TB_DATASET=$${TB_DATASET:-terminal-bench-core==0.1.1}; \ + TB_TIMEOUT=$${TB_TIMEOUT:-1800}; \ + TB_MAX_CONCURRENT=$${TB_MAX_CONCURRENT:-16}; \ + TB_LOAD_THRESHOLD=$${TB_LOAD_THRESHOLD:-1.0}; \ + TB_CHECK_INTERVAL=$${TB_CHECK_INTERVAL:-60}; \ + LIVESTREAM_FLAG=$${TB_LIVESTREAM:+--livestream}; \ + TASK_ID_FLAGS=""; \ + if [ -n "$$TB_SAMPLE_SIZE" ]; then \ + echo "Ensuring dataset $$TB_DATASET is downloaded..."; \ + uvx terminal-bench datasets download --dataset "$$TB_DATASET" 2>&1 | grep -v "already exists" || true; \ + echo "Sampling $$TB_SAMPLE_SIZE tasks from $$TB_DATASET..."; \ + TASK_IDS=$$(python3 benchmarks/terminal_bench/sample_tasks.py --dataset "$$TB_DATASET" --sample-size "$$TB_SAMPLE_SIZE" --format space) || { \ + echo "Error: Failed to sample tasks" >&2; \ + exit 1; \ + }; \ + if [ -z "$$TASK_IDS" ]; then \ + echo "Error: Sampling returned no task IDs" >&2; \ + exit 1; \ + fi; \ + for task_id in $$TASK_IDS; do \ + TASK_ID_FLAGS="$$TASK_ID_FLAGS --task-id $$task_id"; \ + done; \ + echo "Selected task IDs: $$TASK_IDS"; \ + fi; \ + echo "Running adaptive terminal-bench (max concurrency: $$TB_MAX_CONCURRENT, load threshold: $$TB_LOAD_THRESHOLD)"; \ + python3 benchmarks/terminal_bench/adaptive_bench.py \ + --max-concurrent $$TB_MAX_CONCURRENT \ + --load-threshold $$TB_LOAD_THRESHOLD \ + --check-interval $$TB_CHECK_INTERVAL \ + -- \ + --dataset "$$TB_DATASET" \ + --agent-import-path benchmarks.terminal_bench.cmux_agent:CmuxAgent \ + --global-agent-timeout-sec $$TB_TIMEOUT \ + $$LIVESTREAM_FLAG \ + $$TASK_ID_FLAGS \ + $${TB_ARGS} + ## Clean clean: ## Clean build artifacts @echo "Cleaning build artifacts..." diff --git a/benchmarks/terminal_bench/README.md b/benchmarks/terminal_bench/README.md index c106c8804..4f723db1a 100644 --- a/benchmarks/terminal_bench/README.md +++ b/benchmarks/terminal_bench/README.md @@ -99,6 +99,65 @@ Based on analysis of the Oct 30 nightly run (15-minute timeout): **Impact of 30-minute timeout**: Expected to reduce false timeout failures by ~50% and improve pass rates by 10-15 percentage points (from ~42% to ~52-57%). +## Adaptive Concurrency Mode + +The `benchmark-terminal-adaptive` target automatically adjusts concurrency based on system load using a **burst-and-resume pattern**: + +```bash +# Start with concurrency=1, scale up to max 16 based on load +TB_MAX_CONCURRENT=16 make benchmark-terminal-adaptive + +# More conservative: max 8, higher load threshold +TB_MAX_CONCURRENT=8 TB_LOAD_THRESHOLD=2.0 make benchmark-terminal-adaptive + +# Faster adjustments: check every 30 seconds +TB_CHECK_INTERVAL=30 TB_MAX_CONCURRENT=16 make benchmark-terminal-adaptive + +# Sample 5 tasks with adaptive concurrency +TB_SAMPLE_SIZE=5 TB_MAX_CONCURRENT=8 make benchmark-terminal-adaptive +``` + +### How It Works + +1. **Runs terminal-bench in bursts** with current concurrency +2. **Monitors system load** after each burst completes +3. **Adjusts concurrency** using hysteresis: + - **Double** when 1-minute load avg < threshold + - **Halve** when 1-minute load avg > threshold +4. **Resumes** the run with updated concurrency + +The burst-and-resume pattern leverages terminal-bench's native resume capability to skip completed tasks.

This is critical when the system is overloaded - we need to reduce concurrency on the very next burst, not one burst later. Flow before fix: Burst N completes → adjust_concurrency() → write tb.lock Burst N+1 starts → resume reads OLD tb.lock value Flow after fix: adjust_concurrency() completes Burst N+1 starts → write tb.lock → resume reads NEW tb.lock value --- benchmarks/terminal_bench/adaptive_bench.py | 28 ++++++++++--------- .../terminal_bench/adaptive_bench_test.py | 8 ++---- 2 files changed, 17 insertions(+), 19 deletions(-) diff --git a/benchmarks/terminal_bench/adaptive_bench.py b/benchmarks/terminal_bench/adaptive_bench.py index 2fc56daa4..8d47e1054 100755 --- a/benchmarks/terminal_bench/adaptive_bench.py +++ b/benchmarks/terminal_bench/adaptive_bench.py @@ -19,14 +19,14 @@ class AdaptiveBench: """ Adaptive concurrency wrapper for terminal-bench. - + Concurrency is automatically bounded to [1, 16] for optimal performance across different hardware configurations.
