Following is an insert from the switch topology file for this configuration that
shows how the nodes are connected to the High Performance Switch:

Figure 58. Topology File Insert f r o m a Single Switch 16 Wide Node System

Note that the node numbering does not follow the usual convention. For
example, where you would normally expect to see “L01-N2,” there is “L01-N3.”
The node numbering in relation to the slot numbers remains consistent, but the
physical cabling has changed to enable the connection of 16 wide nodes to the
same switch board. The J16 cable now goes to slot 3 (node 3) instead of slot 2
(node 2). This pattern continues up through the 2 frames.

This has an effect on how the nodes are allocated in the various layouts. Using
the 4_12 example again, here is one of the possible configurations:

4 partition

Nodes 1, 3, 9, and 11

12 partition

Nodes 5, 7, 13, 15, 17, 19, 21, 23, 25, 27, 29, and 31

Using the topology files in this way is the only accurate method that can be used
to assess the impact of System Partitioning on all possible RS/6000 SP
configurations. However, using the

slot number method is perfectly valid for

configurations where a single switch services nodes in a single frame only.

If there was no High Performance Switch in this example of a 2 frame, 16 wide
node system, then the partitioning is done with the expectation that there would
be a High Performance Switch in each of the 2 frames, and so you would use the
slot number method to assess the impact of the various layouts on your
configuration.
