HP XC System 3.x Software - Manual (Page 105)

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.
Determine the address of your monitor's display server, as shown at the beginning of “Running an X
Terminal Session from a Remote Node” . You can start an X terminal session using this address information
in a bsub command with the appropriate options. For example:
$ bsub -n4 -Ip srun -n1 xterm -display 14.26.206.134:0.0
Job <159> is submitted to default queue .
<>
<>
The options used in this command are:
-n4
allocate 4 cores
-Ip interact with the X terminal session
srun -n1 run the job on 1 core
xterm the job is an X terminal session
-display monitor's display server address
A remote X terminal session appears on your monitor. The X terminal session job is launched from node
n47
, which is the LSF execution host node. You can view this job using LSF-HPC and SLURM commands.
For example:
$ sinfo
PARTITION AVAIL TIMELIMIT NODES STATE NODELIST
lsf up infinite 2 alloc n[46,48]
$ squeue
JOBID PARTITION NAME USER ST TIME NODES NODELIST
117 lsf hptclsf@ username R 0:25 2 n[46,48]
$ bjobs
JOBID USER STAT QUEUE FROM_HOST EXEC_HOST JOB_NAME SUBMIT_TIME
119 lsfadmi RUN norma n48 4*n47 *8.136:0.0 date and time
You can now run some jobs from the X terminal session that you started and make use of the full allocation
within the LSF-HPC node allocation. For example:
$ srun -n4 hostname
n46
n48
n46
n48
$ srun -n2 hostname
n46
n48
Exiting from the X terminal session ends the LSF-HPC job.
11.3 Using the GNU Parallel Make Capability
By default, the make command invokes the GNU make program. GNU make has the ability to make
independent targets concurrently. For example, if building a program requires compiling 10 source files,
and the compilations can be done independently, make can manage multiple compilations at once — the
number of jobs is user selectable. More precisely, each target's rules are run normally (sequentially within
