Hey Suzanne,

In order to "combine" RAM between different systems, you will need a
hardware/software solution like ScaleMP, or you need a software framework
like OpenMPI.  If your software is already written to use MPI then, in a
sense, it is "combining" the memory.

SLURM is a resource manager and only helps you allocate and track the usage
of the memory.

Here is an example link you may find useful:
