« Logon to the cluster system »
cluster.ma.utexas.edu is your gateway to the
cluster system. It is also the file server and job manager
for the cluster system. To access cluster, run from a terminal
window
ssh cluster.ma.utexas.edu
The first time you sign on, there are no files in your
home directory. This is because your home directory
on the cluster system is independent from that
on our local network. You can access your personal files
from your network home directory by changing
directory to /HOME/$USER, where $USER is your
login name. For example,
ls /HOME/$USER
should list all files in your network home directory. Be warned
that /HOME/$USER is only accessible on
cluster.ma.utexas.edu. To make files visible
by other nodes on the cluster system, you need to copy
them to your home directory on cluster. For example,
cp /HOME/$USER/program.dat ~/
will make program.dat available as ~/program.dat on
all cluster nodes.
Computing nodes on the cluster system
Computing nodes on the cluster system are named
amd1, amd2, ... amd45, amd46, with amd46 being the
gateway host cluster.ma.utexas.edu. Once logged on
to cluster, you can access other nodes, or run
commands on other computing nodes via the r-commands.
For example, the command
rsh amd10
will sign you on to node amd10, and
rsh amd40 uptime
will run the command uptime on amd40.
