Running encoder with lamexec

Hi,  
I was hoping someone could clarify some stuff for me.

My setup works great for the octave examples,

I'm trying to run a video encoder using lamexec on a 4 node Pelican Cluster.
My binaries are installed in /home/user/bin, and my data drive is an nfs mounted hard drive on the origin node.  


I'm running the command lamexec N /home/user/bin/encoder-binary --param1 --param2 --paramn

The command looks like it executes on all the nodes, but it seems like they're not distributing the load across all four nodes.  It looks like each node is running the task individually.

Can pelican HPC split the load of a binary designed to work on a single system?  Or does the application need to be "pelican" aware?

Thanks!
