PROFILE

Rohan Vardhan

Worked on enhancing stability in distributed machine learning pipelines by implementing FP8 rowwise padding for AllToAll pooled embeddings in the pytorch/torchrec and pytorch/FBGEMM repositories. Addressed evaluation-time crashes with small or irregular batch sizes by ensuring input lengths are divisible by the row dimension, applying zero-filled padding before communication and stripping it after decoding. Integrated this approach into both quantization and communication paths, maintaining model output consistency while improving CI and test reliability. Demonstrated expertise in Python, PyTorch, and distributed systems, with a focus on maintainable code and cross-repository consistency in quantization and data processing workflows.

May 2026 performance summary: Delivered stability-first FP8 rowwise padding across TorchRec and FBGEMM to stabilize AllToAll pooled embeddings during evaluation, especially with small batches and irregular embedding sums. Implemented padding in quantization and communication paths (fixed- and variable-batch) so input lengths are divisible by the row dimension, padding before communication and stripping after decoding. Ensured no changes to model output while improving resilience and CI/test reliability. Aligns with existing padding patterns (MX4) and reinforces end-to-end quantization/communication pipeline.
