HP XC System 4.x Software - Manual (Page 108)

$ 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 192.0.2.134
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.
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 192.0.2.134:0.0
The options used in this command are:
srun -N1 run the job on 1 node
xterm the job is an X terminal session
-display 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
This section shows how to create an X terminal session on a remote node using LSF. In this
example, suppose that you want to use LSF 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:
