# Muon Optimizer Test

This directory contains a test script for the **Muon optimizer**.

To execute the test, simply run:

```bash
# By default, the test will use 8 GPUs.
./run_test.sh
```

The number of GPUs can be controlled with the NGPU environment variable.
For example, to run with 4 GPUs:

```bash
NGPU=4 ./run_test.sh
```

## Limitations:
- Multi-node execution is not supported yet.
- Ensure that the specified number of GPUs is available on your machine before running.
