OLCF System Hostnames

See this article in context within the following user guides: Eos | Rhea | Titan

Each OLCF system has a single, designated hostname for general user-initiated user connections. Sometimes this is a load-balancing mechanism that will send users to other hosts as needed. In any case, the designated OLCF host names for general user connections are as follows:

System Name Hostname RSA Key Fingerprint
Titan titan.ccs.ornl.gov 77:dd:c9:2c:65:2f:c3:89:d6:24:a6:57:26:b5:9b:b7
Rhea rhea.ccs.ornl.gov 9a:72:79:cf:9e:47:33:d1:91:dd:4d:4e:e4:de:25:33
Eos eos.ccs.ornl.gov e3:ae:eb:12:0d:b1:4c:0b:6e:53:40:5c:e7:8a:0d:19
