Host Redirection
Host Redirection
Examples
@ character
Host redirection overrides the task lists, so you can force commands from your
local task list to execute on a remote host or override the resource
requirements for a command.
You can explicitly specify the eligibility of a command-line for remote
execution using the @ character. It may be anywhere in the command line
except in the first position (@ as the first character on the line is used to set the
value of shell variables).
You can restrict who can use @ for host redirection in lstcsh with the
parameter LSF_SHELL_AT_USERS in lsf.conf. See the Platform LSF
Reference for more details.
% hostname @hostD
>

% hostname @/type==alpha

hostB
@
@ followed by nothing means that the command line is eligible for
remote execution.
@host_nam @ followed by a host name forces the command line to be executed
e
on that host.
@local @ followed by the reserved word local forces the command line
to be executed on the local host only.
@/res_req @ followed by / and a resource requirement string means that the
command is eligible for remote execution and that the specified
resource requirements must be used instead of those in the remote
task list.
For ease of use, the host names and the reserved word local following @ can
all be abbreviated as long as they do not cause ambiguity.
Similarly, when specifying resource requirements following the @, it is
necessary to use / only if the first requirement characters specified are also the
first characters of a host name. You do not have to type in resource
requirements for each command line you type if you put these task names into
remote task list together with their resource requirements by running
lsrtasks.
