--------------------
There are some limitations for PRACE user when using the cluster. By default PRACE users aren't allowed to access special queues in the PBS Pro to have high priority or exclusive access to some special equipment like accelerated nodes and high memory (fat) nodes. There may be also restrictions obtaining a working license for the commercial software installed on the cluster, mostly because of the license agreement or because of insufficient amount of licenses.
For production runs always use scratch file systems. The available file systems are described [here](storage/storage/).

### Accounting & Quota
The resources that are currently subject to accounting are the core hours. The core hours are accounted on the wall clock basis. The accounting runs whenever the computational cores are allocated or blocked via the PBS Pro workload manager (the qsub command), regardless of whether the cores are actually used for any calculation. See [example in the general documentation](resource-allocation-and-job-execution/resources-allocation-policy/).

PRACE users should check their project accounting using the [PRACE Accounting Tool (DART)](http://www.prace-ri.eu/accounting-report-tool/).
