# `pcluster`
<a name="pcluster-v3"></a>

`pcluster` is the primary AWS ParallelCluster CLI command. You use `pcluster` to launch and manage HPC clusters in the AWS Cloud.

`pcluster` writes logs of your commands to `pcluster.log.#` files in `/home/user/.parallelcluster/`. For more information, see [`pcluster` CLI logs](troubleshooting-v3-pc-cli-logs.md).

To use `pcluster`, you must have an IAM role with the [permissions](iam-roles-in-parallelcluster-v3.md#iam-roles-in-parallelcluster-v3-example-user-policies) required to run it.

```
pcluster [-h]
```
