RW Solver

Requirements

• Linux x86-64 (Ubuntu 20.04 or later is recommended)
• Python 3.8 with libpython3.8.so.1.0
• A CUDA-capable NVIDIA GPU
• An NVIDIA driver compatible with the GPU
• pip

Create a Python virtual environment and install the required packages:

python3.8 -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip
python -m pip install -r requirements.txt

requirements.txt contains all required Python packages. The NVIDIA driver is a system component and must be installed separately.

Usage example

./rw_solver \
  --input testcase20.sp \
  --gt testcase20.csv \
  --pred pred_testcase20.csv \
  --tol 5e-5 \
  --gpu 0,1 \
  --ratio 0.1

Arguments:

• --input: input SPICE file or THUPG .mtx file
• --gt: ground-truth CSV file
• --pred: initial prediction CSV file
• --tol: relative convergence tolerance; defaults to 5e-5
• --gpu: one GPU ID or comma-separated GPU IDs; defaults to 0
• --ratio: fraction of active nodes to solve; defaults to 0.1

The --input, --gt, and --pred arguments are required.
