[OMPI users] Some Newbie questions

[Ashika Umanga Umagiliya]

Greeting all,

I am new to Open MPI and I have some newbie questions. I have given 4 
machines at our laboratory to set up Open MPI.Our net work is simply 
TCP/Ethernet running Debian Linux.

1) After installing OpenMPI on each machine ,do i need to run a 
service/daemon on each machine? (How does peers in MPI environment 
communicate ?)

2) After implementing parallel program , do I have to install the 
application on every machine ? (I thought the program automatically 
propagated to other peers , like in RMI applications? )



Thanks in advance,
Umanga
