# Optimizing Tensor Parallelism in JAX and XLA

> **Draft** — this page is a placeholder. Content is in progress.

## Background

{/* Why TP matters: model sizes past single-GPU memory, the compute/communication
tradeoff versus FSDP and pipeline parallelism. */}

## Where tensor parallelism costs performance

{/* All-gather / reduce-scatter on the critical path, exposed communication,
small GEMM tiles at high TP degree, NVLink versus inter-node bandwidth. */}

## Optimizations

{/* One subsection per optimization, with the mechanism and how to enable it. */}

## Results

{/* Model, hardware, TP degrees swept, throughput and step-time deltas. */}

## Reproducing

{/* Container tag, framework config flags, launch command. */}

## Takeaways
