Here's a simple example which seems to work on my end. It requests a
entire machine using the TotalCpus attribute:

Universe = vanilla
Executable = /bin/sleep
Arguments = 60
Output = test.out
Error = test.err
Requirements = (TARGET.TotalCpus =!= UNDEFINED) && \
((Target.PartitionableSlot =?= TRUE) || (TARGET.DynamicSlot =?= TRUE))
# Request an entire machine
request_cpus = TARGET.TotalCpus
queue

I think this should do what you want, but as we only have 8 core
systems, it is hard for me to test all the possibilities you laid out
(2, 4, 8, 16). Let me know if it works.

Have a good day,
