Thanks! Probably im reading documentation not very thoroughly. Ask again.
Have you a running mechanizm that does not use any network protocols?
I want to run lamboot but when LAM is in booting stage it must not
set any network connections between other machines and to localhost. If it
is allowed for user to call rsh/ssh or other remote calls then after user
time left LoadLeveler will not be able to finalize spawned processes that
run by ssh or other remote call program.
We intent to use LAM as simulator distributed memory over shared memory
and use messages as a way to organize interconection between processors in
SMP system.
