Effective but stingy installation of MDCS

If there are 3 nodes and 12 cores each, mdcs has to be installed in all 36 cores right?
Now for the nodes to communicate with each other, is installing mdcs in 1 core (or the master) of each node enough for the nodes to communicate with each other? Since we can use PCT to work with the cores within the system, we don't need to install MDCS in every core right?
This might mean a compromise on speed but is it possible?

MDCS is to be installed in each node not per core. You can use one MDCS worker per node which utilizes one CPU core and also launch multiple workers (for example, 12 workers which utilizes 12 cores) as much as the maximum number of your MDCS worker license.

Thank you for your reply. You said only 1 core is used per node right? But I can use the Parallel Computing Toolbox to perform intra-node functions right? Meaning use the toolbox to make this one core communicate with other 11 cores within the node.

The default is that each worker has one computational thread. You can change that in the cluster profile to allow the use of more computational threads per worker.
