7.6 Working Interactively Within an LSF-HPC Allocation

The best way to work interactively within an LSF-HPC allocation is to submit an interactive
job to LSF-HPC that launches the

xterm

program on the first allocated node. This requires

that your display support an external display connection from another computer. See Section
Section 7.6.1 for information on this approach.

If this is not possible, then the next best method is submitting an interactive job to launch a
shell. See Section 7.6.2 for more information on this approach.

7.6.1 Submitting an Interactive Job to Launch the

xterm

Program

The following is a general procedure for launching the

xterm

program, because there are

several ways in which a user can log into an HP XC system:

1.

Ensure that your display supports and permits a connection from the HP XC system.

For UNIX and Linux desktops, the easiest but least secure method is to run the following
command on your local desktop.

$ xhost +

See the xhost manpage for more information on this command.

2.

Login into the HP XC system and set the

DISPLAY

environment variable to your desktop

machine.

For example, if your desktop machine is

mymachine.lab.example.com

and your

shell is the Korn shell, enter the following:

$ export DISPLAY=mymachine.lab.example.com:0.0

3.

Test your display configuration by executing the

xterm

command. You should see a

terminal window show up on your display. Enter

exit

in the

xterm

window to close

the window and end execution.

Debug your display connection if the terminal window did not appear.

4.

Submit a job with the resources necessary for your interactive session, and launch the

xterm

program. The following sample command line requests four nodes:
