Setting up RMS
• Is the machine primarily for running parallel jobs or do you expect a significant
workload from sequential jobs?
• Will some of your users have jobs that consume all of the resources of the system for
extended periods of time? If so, are you happy for other users to wait until the
machine is available or do they need access to resources of their own?
• How do you wish to process the accounting data?
The answers to these questions should help you to determine how to configure the
system. It may be that you cannot answer these questions, in which case you should
start with one of the basic configurations described below.
9.2.1 Node Names
While planning the machine installation give some thought to its name and the names
of its nodes. We recommend selection of a short name for the machine (for example
atlas). Node names should use the name of the machine as a base and their network
port number as a suffix (for example atlas0, atlas1, ..., atlas63). RMS will
compress such lists of hostnames (for example atlas[0-63]).
Some machines have a management server node that is connected to the management
network but is not connected to the Compaq AlphaServer SC Interconnect. By
convention, this node is given the suffix ms (for example atlasms).
9.3 Setting up RMS
RMS should be installed according to the instructions in the Compaq AlphaServer SC
Installation Guide.
For the purposes of this section, we assume a machine with 64 nodes, where each node
has 4 CPUs, 4GB of memory and an 18GB disk. You should make adjustments for the
actual number of nodes in your system. If RMS is already running on the machine, skip
to Section 9.3.2.
9.3.1 Starting RMS
The RMS initialization script, /sbin/init.d/rms, is run on each node with the
argument start as the node boots. Conversely, when the node halts, the script is run
with the stop argument.
To start or stop RMS manually on all of the nodes at once, run rmsctl on the rmshost
node with the appropriate argument (start or stop). This command runs
/sbin/init.d/rms on each of the nodes in turn. rsh must be enabled for root users
