gpu-optimizer SKILL.md skillA
gpu-optimizer from mathews-tom/armory is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add mathews-tom/armory/gpu-optimizer@v1.1.1Pins v1.1.1 in mdr.lock. Pin the fingerprint instead.

GPU optimization for consumer NVIDIA GPUs (8-24GB VRAM) covering mixed precision, gradient checkpointing, XGBoost GPU, CuPy/cuDF migration, and torch.compile. Triggers on: "optimize GPU training", "speed up CUDA", "reduce OOM", "migrate NumPy to CuPy", "manage GPU memory", "benchmark PyTorch".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# GPU Optimizer Expert GPU optimization for consumer GPUs with 8–24GB VRAM. Evidence-based patterns only. ## Hardware Profile Fill in your hardware before applying optimizations: | Property | Your Value | | ----------------- | ------------------------------------------------ | | GPU model | (e.g., RTX 4080 Mobile, RTX 3090, RTX 4090) | | VRAM | (e.g., 12GB, 16GB, 24GB) | | CUDA version | (`nvidia-smi` → top-right) | | TDP / power limit | (laptop vs desktop affects sustained throughput) | | Driver version | (`nvidia-smi` → top-left) | Key constraint: VRAM capacity determines which strategies apply. Patterns below are annotated with minimum VRAM requirements where relevant. ## Optimization Categories ### 1. XGBoost GPU Acceleration **DMatrix vs QuantileDMatrix:** ```python # GPU-optimized: QuantileDMatrix is 1.8x faster dtrain = xgb.QuantileDMatrix(X_train.astype(np.float32)) dval = xgb.QuantileDMatrix(X_val.astype(np.float32)) # Standard: DMatrix (use for inference only) dtest = xgb.DMatrix(X_test.astype(np.float32)) ``` …

How to install
mdr add mathews-tom/armory/gpu-optimizer@sha256:8ddd111b6b0be8d0The line at the top of this page pins the label v1.1.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
