as Bjoern already mentioned, normally you start the server program once
on each machine (so in total there are as many server programs running
as there are displays) that should render an image and the client
program exactly once.
The commands above look as if all the server programs run on a single
computer, only their output is sent to different machines. I'd expect
the sequence to look more like this:
ssh display1
./myclusterserver -geometry 300x300+200+100 -m display1
exit
ssh display2
./myclusterserver -geometry 300x300+200+100 -m display2
exit
etc.
and then the client as above.
Hope it helps,
Carsten
