About Interactive Jobs
It is sometimes desirable from a system management point of view to control all
workload through a single centralized scheduler.
Running an interactive job through the LSF batch system allows you to take
advantage of batch scheduling policies and host selection features for
resource-intensive jobs. You can submit a job and the least loaded host is selected
to run the job.
Since all interactive batch jobs are subject to LSF policies, you will have more
control over your system. For example, you may dedicate two servers as interactive
servers, and disable interactive access to all other servers by defining an interactive
queue that only uses the two interactive servers.
Scheduling policies
Running an interactive batch job allows you to take advantage of batch scheduling
policies and host selection features for resource-intensive jobs.
An interactive batch job is scheduled using the same policy as all other jobs in a
queue. This means an interactive job can wait for a long time before it gets
dispatched. If fast response time is required, interactive jobs should be submitted to
high-priority queues with loose scheduling constraints.
