$ echo $DISPLAY
:0

Next, get the name of the local machine serving your display monitor:

$ hostname
mymachine

Then, use the host name of your local machine to retrieve its IP address:

$ host mymachine
mymachine has address 14.26.206.134

Step 2. Logging in to HP XC System

Next, you need to log in to a login node on the HP XC system. For example:

$ ssh user@xc-node-name

Once logged in to the HP XC system, you can start an X terminal session using SLURM or
LSF-HPC. Both methods are described in the following sections.

Step 3. Running an X terminal Session Using SLURM

This section shows how to create an X terminal session on a remote node using SLURM. First,
examine the available nodes on the HP XC system. For example:

$ sinfo
PARTITION AVAIL TIMELIMIT NODES STATE NODELIST
lsf up infinite 2 idle n[46,48]

According to the information returned about this HP XC system, SLURM has two nodes, n46
and n48, available for use.

Start an X terminal session on this node, using the information you obtained about your display
server to direct output back to it. For example:

$ srun -N1 xterm -display 14.26.206.134:0.0

The options used in this command are:

srun -N1

run the job on 1 node

xterm

the job is an X terminal session

-display <address>

monitor's display server address

Once the job starts, an X terminal session appears on your desktop from the available remote
HP XC node. You can verify that the X terminal session is running on a compute node with the
hostname

command. For example:

$ hostname
n47

You can verify that SLURM has allocated the job as you specified. For example:

$ sinfo
PARTITION AVAIL TIMELIMIT NODES STATE NODELIST
lsf up infinite 2 idle n[46,48]
$ squeue
JOBID PARTITION NAME USER ST TIME NODES NODELIST
135 srun xterm username R 0:13 1 n47

Exiting from the X terminal session ends the SLURM job.

Step 4. Running an X terminal Session Using LSF-HPC

This section shows how to create an X terminal session on a remote node using LSF-HPC. In this
example, suppose that you want to use LSF-HPC to reserve 4 cores (2 nodes) and start an X
terminal session on one of them.

First, examine the available nodes on the HP XC system. For example:
