## Network



There is a 10 Gbit Ethernet switch ([TP-Link T1700X-16TS](https://www.tp-link.com/us/business-networking/smart-switch/t1700x-16ts/)) that provides fast interconnection among the following nodes:

There is a 10 Gbit Ethernet switch ([TP-Link T1700X-16TS](https://www.tp-link.com/us/business-networking/smart-switch/t1700x-16ts/)) that provides fast interconnection among the nodes:



- compute nodes `gp11`-`gp14`

- login nodes `gp1.fjfi.cvut.cz`-`gp8.fjfi.cvut.cz`



The node `gp9.fjfi.cvut.cz` is not connected to the 10 Gbit switch and its use for distributed computations is therefore very inefficient.



Internet access from the compute nodes is provided via [NAT](https://en.wikipedia.org/wiki/Network_address_translation) on the login nodes connected to the 10 Gbit network.
