LSF master host

The overall LSF coordinator for the system. The master load information manager (LIM) and
master batch daemon (

mbatchd

) run on the LSF master host. Each system has one master host

to do all job scheduling and dispatch. If the master host goes down, another LSF server in the
system becomes the master host.

LVS

Linux Virtual Server. Provides a centralized login capability for system users. LVS handles
incoming login requests and directs them to a node with a login role.

N

NAT

Network Address Translation. A mechanism that provides a mapping (or transformation) of
addresses from one network to another. This allows external access of a machine on one LAN
that has the same IP address as a machine on another LAN, by mapping the LAN address of the
two machines to different external IP addresses.

Network Address Translation

See NAT

Network Information Services

See NIS

NIS

Network Information Services. A mechanism that allows centralization of common data that
is pertinent across multiple machines in a network. The data is collected in a domain, within
which it is accessible and relevant. The most common use of NIS is to maintain user account
information across a set of networked hosts.
