Load Sharing X Applications
Setting up Exceed to log on the least loaded host
To set up Exceed to log on to the least loaded host:
1 Click the Xstart icon in the Exceed program group.
2 Choose REXEC (TCP/IP, ...) as start method, program type is X window.
3 Set the host to be any server host in your LSF cluster:
lsrun -R "type==any order[cpu:mem:login]" lsbg xterm -sb -
ls -display your_PC:0.0
4 Set description to be Best.
Starting an xterm in Exceed
Examples
5 Click the Install button in the Xstart window.
This installs Best as an icon in the program group you chose (for example,
xterm).
The user can now log on to the best host by clicking Best in the Xterm
program group.
To start an xterm:
◆ Double-click the Best icon.
You will get an xterm started on the least loaded host in the cluster and
displayed on your screen.
Running any application on the least loaded host
To run appY on the best machine licensed for it, you could set the command
line in Exceed to be the following and set the description to appY:
lsrun -R "type==any && appY order[mem:cpu]" sh -c "appY -display your_PC:0.0 &"
You must make sure that all the UNIX servers licensed for appY are configured
with the resource "appY". In this example, appY requires a lot of memory when
there are embedded graphics, so we make "mem" the most important
consideration in selecting the best host among the eligible servers.
Starting an X session on the least loaded host in any X desktop environment
The above approach also applies to other X desktop environments. In general,
if you want to start an X session on the best host, run the following on an LSF
host:
lsrun -R "resource_requirement" lsbg my_Xapp -display your_PC:0.0
where
resource_requirement is your resource requirement string
