Interactive Tasks
Chapter 33
Running Interactive and Remote Tasks
LSF supports transparent execution of tasks on all server hosts in the cluster.
You can run your program on the best available host and interact with it just
as if it were running directly on your workstation. Keyboard signals such as
CTRL-Z and CTRL-C work as expected.
Interactive tasks communicate with the user in real time. Programs like vi use
a text-based terminal interface. Computer Aided Design and desktop
publishing applications usually use a graphic user interface (GUI).
This section outlines issues for running interactive tasks with the non-batch
utilities lsrun, lsgrun, etc. To run interactive tasks with these utilities, use the
-i option.
For more details, see the lsrun(1) and lsgrun(1) man pages.

Interactive tasks on remote hosts
Job controls
Hiding remote
execution
When you run an interactive task on a remote host, you can perform most of
the job controls as if it were running locally. If your shell supports job control,
you can suspend and resume the task and bring the task to background or
foreground as if it were a local task.
For a complete description, see the lsrun(1) man page.
You can also write one-line shell scripts or csh aliases to hide remote
execution. For example:
#!/bin/sh
# Script to remotely execute mytask
exec lsrun -m hostD mytask
OR
% alias mytask "lsrun -m hostD mytask"
Interactive processing and scheduling policies
LSF lets you run interactive tasks on any computer on the network, using your
own terminal or workstation. Interactive tasks run immediately and normally
require some input through a text-based or graphical user interface. All the
input and output is transparently sent between the local host and the job
execution host.
