# Experiment 1 Cell A + B full capture — benchmark + nvidia-smi GPU profiling.
# Runs Cell A (direct tools) and Cell B (MCP baseline) sequentially in one
# Slurm allocation so both cells share the same node environment and GPU type.
#
# Phase 1 for each cell: run_experiment.sh handles vLLM lifecycle, the 3-trial
# multi-domain scenario loop, WandB upload, and (when TORCH_PROFILE=1) the
# vLLM torch-profiler replay pass while vLLM is still alive.
#
# Phase 2 for each cell: capture_around.sh wraps the Phase 1 command and
# records a background nvidia-smi CSV timeline, then calls
# log_profiling_to_wandb.py to attach gpu-util / memory stats to the
# benchmark's WandB run.
#
# Usage:
#   # Set MAIL_USER once (e.g. in ~/.bashrc on Insomnia):
#   #   export MAIL_USER="${USER}@example.edu"
#   sbatch --mail-type=BEGIN,END,FAIL --mail-user="$MAIL_USER" \
#       scripts/run_exp1_ab_capture.sh
#
# After the job completes, find artifacts at:
#   benchmarks/cell_A_direct/raw/<SLURM_JOB_ID>_aat_direct/
#   benchmarks/cell_B_mcp_baseline/raw/<SLURM_JOB_ID>_aat_mcp_baseline/
#   profiling/traces/<SLURM_JOB_ID>_cell_a/        (nvidia_smi.csv, capture_meta.json)
#   profiling/traces/<SLURM_JOB_ID>_cell_b/
#   profiling/traces/<SLURM_JOB_ID>_aat_direct_torch/     (*.pt.trace.json.gz, if profiler ran)
#   profiling/traces/<SLURM_JOB_ID>_aat_mcp_baseline_torch/
#
# To disable the torch-profiler replay for a faster run:
#   TORCH_PROFILE=0 sbatch scripts/run_exp1_ab_capture.sh
