I don't understand that sentence.

Corosync and pacemaker are for High Availability, which generally means that 
you have more computing resources than you need at any given time, in order 
that a failed machine can be efficiently replaced by a working one.  If all your 
machines are busy, and one fails, you have no spare computing resources to 
take over from the failed one.

The setup you were asking about is High Performance computing, where you are 
trying to use the resources you have as efficiently and continuously as 
possible, therefore you don't have any spare capacity (since 'spare' means 
'wasted' in this regard).

A Beowulf Cluster is one example of the sort of thing you're asking about; for 
others, see the "Implementations" section of the URL I previously provided.
