Llama-3.2-3B-Aurora-Chat v3

LoRA fine-tune of meta-llama/Llama-3.2-3B-Instruct specialized for the ALCF Aurora supercomputer (Intel Xeon Sapphire Rapids + Intel GPU Max 1550 / Ponte Vecchio, oneAPI / SYCL, PBS Pro).

Off-the-shelf code-LLMs hallucinate Aurora specifics — they suggest nvcc instead of icpx -fsycl, srun / aprun instead of mpiexec, NERSC's /global/cfs instead of /lus/flare, and CUDA device strings instead of xpu. This adapter teaches the base model the actual Aurora toolchain, file system layout, scheduler conventions, and recommended PyTorch/TensorFlow/SYCL idioms.

Quick start

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

tok = AutoTokenizer.from_pretrained("shazzadulimun/llama32-3b-aurora-chat-v3")
mdl = AutoModelForCausalLM.from_pretrained("shazzadulimun/llama32-3b-aurora-chat-v3", torch_dtype=torch.bfloat16, device_map="auto")

msgs = [{"role": "user", "content": "How do I launch one MPI rank per Aurora GPU tile?"}]
ids = tok(tok.apply_chat_template(msgs, tokenize=False, add_generation_prompt=True), return_tensors="pt").to(mdl.device)
print(tok.decode(mdl.generate(**ids, max_new_tokens=400, temperature=0.0)[0][ids.input_ids.shape[1]:], skip_special_tokens=True))

Training data

Distilled from openai/gpt-oss-120b on ALCF Sophia (vLLM) over 416 cleaned chunks of docs.alcf.anl.gov/aurora. 4,495 training rows + 562 validation rows in ChatML format with embedded chain-of-thought (**Reasoning:** / **Answer:**).

Broad coverage, parallel-rank distillation. 20 worker ranks each took a disjoint slice (~21 chunks) of the cleaned docs.alcf.anl.gov/aurora corpus and asked the teacher for chain-of-thought QA pairs. Disjoint slicing maximizes phrasing diversity (each rank sees fresh context) while still covering every chunk exactly once.

Evaluation

Part of the v3 parameter-size sweep (1B → 120B trained on the same dataset). Holdout scorecard appears here once the full sweep completes.

Limitations

• Synthetic-data biases. Teacher (gpt-oss-120b) can confabulate plausible-looking but incorrect commands. Treat outputs as a verifiable first draft, not authoritative.
• Doc snapshot is fixed at 2026-04-29. Module versions, queue names, and APIs change — anything published after that date isn't reflected here.
• Aurora-only. Specifics (/lus/flare, xpu, PBS queues) won't transfer to Frontier, Polaris, or other systems.
• Use temperature ≤ 0.1 for technical answers; higher temps invite invented flag names and paths.
