With regards to the topology for nested performance testing, I think a 
more-complicated but reasonably typical nested topology would be a 
compute node with something like 2/4 numa nodes, with a mix of memory 
page sizes (4K/2MB/1GB),  with HyperThreading, and with a few NUMA-aware 
PCI devices (SRIOV, FPGA, vGPU, etc.).
