# Tune NVSHMEM Performance

## Purpose

Guide the user to the smallest applicable NVSHMEM performance workflow. Offer optional baseline collection and three focused optimization services while preserving each specialist's inputs, execution boundary, and safety rules.

Do not reproduce the specialists' technical guidance in this router. Invoke:

| User goal | Specialist |
| --- | --- |
| Collect a baseline, run perftests, or package system and benchmark evidence | `$nvshmem-collect-performance-data` |
| Select an inter-node remote transport | `$nvshmem-select-remote-transport` |
| Select HCAs or optimize NIC-to-PE mapping | `$nvshmem-configure-nic-pe-mapping` |
| Assess, prepare, review, or debug NVSHMEM TMA use | `$nvshmem-enable-tma` |
