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.
