Administering Platform LSF - SAS

Automatic Remote Execution
Chapter 43
Using lstcsh
Every time you enter a command, lstcsh looks in your task lists to determine
whether the command can be executed on a remote host and to find the
configured resource requirements for the command.
See the Platform LSF Reference for information about task lists and
lsf.task file.
If the command can be executed on a remote host, lstcsh contacts LIM to
find the best available host.
The first time a command is run on a remote host, a server shell is started on
that host. The command is sent to the server shell, and the server shell starts
the command on the remote host. All commands sent to the same host use the
same server shell, so the start-up overhead is only incurred once.
If no host is found that meets the resource requirements of your command, the
command is run on the local host.
