[Beowulf] Programming for heartbeat

[Caio Freitas de Oliveira]

Hi all,

I'm completely new to all this beowulf thing. I've just now connected my 
2 PCs using Heartbeat + Pacemaker, but I don't have a clue of how to use 
them as a single computer. Pacemaker has a number of predefined 
resources but none of them (at least from what I've seen) is what I want.

I've seen OpenMPI, but it uses Oracle's Message Passing Toolkit. Would 
you guys know how could I get a program to work in this beowulf?

Thanks in advance. (:
