TensorDynamic — Artifact Evaluation

TensorDynamic is an NVBit-based fault injection tool targeting Tensor Core (HMMA) instructions. This artifact evaluates fault injection on four DNN models (ResNet20, MobileNetV2, ShuffleNetV2, YOLOv9) using three backends: PyTorchFI, MRFI, and TensorDynamic.

Quickstart

# 1. Create and activate conda environment
conda create -n myenv python=3.10 pip -y
conda activate myenv

# 2. Download and extract NVBit 1.7.6
wget https://github.com/NVlabs/NVBit/releases/download/v1.7.6/nvbit-Linux-x86_64-1.7.6.tar.bz2
tar xvfj nvbit-Linux-x86_64-1.7.6.tar.bz2
cd nvbit_release_x86_64

# 3. Clone this repository
git clone <repo_url> TensorDynamic
cd TensorDynamic

# All subsequent commands should be run from the TensorDynamic/ directory.

# 4. Install dependencies (~5-10 min)
pip install -r requirements.txt

# 5. Set up YOLOv9 repo, dataset, and weights (~5 min)
bash setup_yolo.sh

Table 2 — Fault Injection Observability (Convolution vs. GEMM)

nohup bash table2/table2.sh > table2_run.log 2>&1

Output: table2/results/table2_summary.csv

Estimated time: ~2–3 h

---

Figure 6 — HMMA Register Sparsity

Recommended first step — this is the fastest way to verify your environment is set up correctly before running the longer fault injection sweeps.

bash figure6/figure6.sh

Builds the NVBit profiling tool, runs all four models, parses results, and generates: figure6/reg_dist_plots/combined_sparsity_dest_zero_4panel.png

Estimated time: ~1 h

---

Figure 4 — Fault Injection Accuracy Sweep

Run the full pipeline (sweeps → baselines → parse → plot):

nohup bash figure4/figure4.sh > figure4_run.log 2>&1

Or run each step individually:

# Step 1: PyTorchFI & MRFI sweep (~2-3 h)
nohup bash figure4/sweep_pytorchfi_mrfi.sh > pytorchfi_run.log 2>&1

# Step 2: TensorDynamic sweep (~13-14 h)
nohup bash figure4/sweep_tensordynamic.sh > tensordynamic_run.log 2>&1

# Step 3: Collect baselines, parse results, generate plot
bash figure4/plot_results.sh

Output: figure4/plots/eight_plots.png and figure4/plots/eight_plots.pdf

---

Figure 5 — Baseline vs. Parameter Sensitivity

Run the full pipeline (sweep → parse → plot):

nohup bash figure5/figure5.sh > figure5_run.log 2>&1

Or run each step individually:

# Step 1: Run TensorDynamic sensitivity sweep + PyTorchFI baseline (~8 h)
nohup bash figure5/sweep_baseline.sh > figure5_sweep.log 2>&1

# Step 2: After sweep completes — parse results and generate plot
bash figure5/plot_figure5.sh

Output: figure5/plots/nine_point_plot.png and figure5/plots/nine_point_plot.pdf
