HP XC System 3.x Software Logging in to HP XC System, Running an X terminal Session Using Slurm

$ 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:

$ 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, LSF-HPC has two nodes available for use, n46 and n48.
