How do you change the default memory per node from the current 1MB to
something much higher?
Thanks in advance.

See the slurm.conf manual page:
RealMemory
Size of real memory on the node in megabytes (e.g. "2048"). The default value is 1.
There's a nice command to run on any given node which tells you slurmd's
view of the node:
$ slurmd -C
NodeName=i004 CPUs=16 Boards=1 SocketsPerBoard=2 CoresPerSocket=8
ThreadsPerCore=1 RealMemory=128691
UpTime=36-17:32:44
Here's an example that I use:
NodeName=i[004-030] Sockets=2 CoresPerSocket=8 ThreadsPerCore=1
RealMemory=128000
There is additional information in my Wiki page:
