Manual Backpropagation Triton Kernel Derivations for Parameter-Efficient Cross-Entropy

Published mathematical explanations and Triton code demonstrating how computing gradient chain rules directly inside custom SRAM kernels avoids materializing multi-gigabyte intermediate tensors in PyTorch.

Model & Execution Context:Triton cross-entropy loss, RoPE embedding kernels, RMSNorm gradient fusion.
Scope & Limitations

Custom Triton kernels require deep mathematical derivations for each distinct attention and normalization layer.

Unsloth: Fast and Memory-Efficient Open-Source LLM Fine-Tuning

Created an open-source library that rewrites PyTorch forward and backward passes into handwritten Triton kernels, supporting LoRA, QLoRA, and full fine-tuning with 0% accuracy loss while preventing out-of-memory errors.

Model & Execution Context:Llama 3.1/3.2, Mistral NeMo, DeepSeek-R1-Distill, Gemma 2; 4-bit bitsandbytes and 16-bit mixed precision.
Scope & Limitations

Heavily optimized for NVIDIA Ampere, Ada Lovelace, and Hopper architectures; AMD ROCm support is emerging.
