Nevis Linux Cluster Node Names

  These are the names of the computers in the Nevis Linux Cluster.
Line: 8 to 8
 
  • the systems on the Nevis condor batch farm;
  • the student boxes;
  • machines that are not part of the cluster (e.g., Windows machines, laptops, some ATLAS, DOE, and Neutrino systems).

 Most Linux machines at Nevis are typically used by a particular working group; the student boxes are the main exception, but there are other shared workstations noted below.

Each group has an informal naming convention for its machines. The list below includes the different groups with machines in the cluster, the basis for the names, and description of each Linux machine normally used by that group.

 Named (initially) for characters and locations from the Harry Potter novels by J. K. Rowling. (The student boxes are also shared, but they're described separately.) The reason for mixed naming scheme is these systems were at one time dedicated to specific workgroups.

Why the funny names?

Changed:
<
<		Well, there's the sheer intellectual over-indulgence of it all, but there's also a serious reason: the function of a given computer can change over time; for example, a computer that used to be Jones' Linux desktop client may become an FTP server in the future. If the computer's name was jonespc or d0pc3, we'd want to change it to ftpserver or something like that. If the computer's name was hanuman.nevis.columbia.edu, there'd be no reason to change it, nor any need to update the various databases of names (/etc/hosts, NIS, DNS, etc.).

  Obviously, we have this luxury because there are relatively few computers at Nevis. We can configure them individually and know each one by name. If we had a hundred boxes, this would be impossible. \ No newline at end of file
