===== Software =====
Unlike the cluster (Centos 6.5), the servers are running **Ubuntu Linux**. Thus, the servers do not share any software with the rest of the cluster. In the other word, there is no ''module'' command in the servers.
Software are installed directly on the servers.

We can find all Deep learning software stack: Tensorflow, keras, ... 



===== How to access =====
<note important>Deep-learning servers are only opened for the authorized users.</note>
