    v9 v10  
    269269We can call up the DETER experiment page and look at the visualization tab:

     272
     273The physical node {{{n-9}}} shows up in the DETER visualization, and otherwise acts as a physical node that is in a 11-node topology.  This experiment uses three different container types: physical nodes, ViewOS processes, and Qemu VMs.

    273275=== Changing The Packing Factor ===
    274276
     277The {{{containerize.py}}} program is deciding how many virtual nodes to put on each physical machine.  Because we have been using roughly the same number of nodes as the default packing target (10 nodes per machine) all the examples have fit on a single machine.  If we change the packing factor, using the {{{--packing}}} parameter to {{{containerize.py}}} we can put fewer nodes on each machine.  For example:
     278
     279
     280{{{
     281users:~$ /share/containers/containerize.py --packing 2 DeterTest example1 ~/example1.tcl
     282Containerized experiment DeterTest/example1 successfully created!
     283Access it via http://www.isi.deterlab.net//showexp.php3?pid=DeterTest&eid=example1
     284}}}
     285
     286Calls {{{containerize.py}}} on our [attachment:example1.tcl original topology] with a low packing factor.  The result is the same nodes spread across more physical machines, as we can see from teh DETER web interface (visualization tab):
