HP XC System 3.x Software - Manual (Page 104)

$ 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 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.
