the contents of karthur:/usr/nevis are mirrored nightly to
the backup applications servers: kolya and annex.

Nevis Applications ServerThe students and teachers at Nevis require the use of many common programs: ROOT![]() ![]() ![]() /usr/nevis ) to
all the other systems in the cluster via automount.
Any changes made to the software on the applications server is rapidly
available to the entire cluster.
The current applications server is karthur. For reliability,
the contents of karthur:/usr/nevis are mirrored nightly to
the backup applications servers: kolya and annex.
The automount configuration has been set so that if karthur
goes down, the copy on kolya is used instead (although this
seems to work better in theory than in practice). The Annex![]() annex:/usr/local by default, for speed.
A general question: what programs, applications, or utilities should go on
the applications server? The policy is this: If only one workgroup
uses a software package, then that package should be installed on that
workgroup's server and maintained by that group; for example, the
D0 group maintains the D0 analysis software on their
server, karthur. If a package is used by more than one working
group, or is of general interest (such as ROOT), it's kept on the
applications server and maintained by the Nevis research computer staff. |
