When I specify only -H like so:
mpirun -H localhost -np 1 prog1 : -H A.lan -np 4 prog2 : -H B.lan -np 4 prog2
I get the same error:
"There are not enough slots available in the system to satisfy the 4 slots
that were requested by the application:
Either request fewer slots for your application, or make more slots
available for use".

Yes both A and B have exactly 4 cores each.
