### Advanced Networking
**Internet access**
#### Internet access
Sometime your virtual machine needs access to internet (install software, updates, software activation, etc). We suggest solution using Virtual Distributed Ethernet (VDE) enabled QEMU with SLIRP running on login node tunneled to compute node. Be aware, this setup has very low performance, the worst performance of all described solutions.

## Running Parallel Matlab Using Distributed Computing Toolbox / Engine
Recommended parallel mode for running parallel Matlab on Anselm is MPIEXEC mode. In this mode user allocates resources through PBS prior to starting Matlab. Once resources are granted the main Matlab instance is started on the first compute node assigned to job by PBS and workers are started on all remaining nodes. User can use both interactive and non-interactive PBS sessions. This mode guarantees that the data processing is not performed on login nodes, but all processing is on compute nodes.

### Non-Interactive Session and Licenses
If you want to run batch jobs with Matlab, be sure to request appropriate license features with the PBS Pro scheduler, at least the "` -l __feature__matlab__MATLAB=1`" for EDU variant of Matlab. More information about how to check the license features states and how to request them with PBS Pro, please [look here](../isv_licenses/).
