NAME
     topology - machine topology information

SYNOPSIS
     topology


DESCRIPTION
     Machine topology information is extracted from the hardware graph.


EXAMPLE
     When executed on a 16 processor Origin2000 named olympic, the topology
     command yields:

     Machine olympic has 16 cpu's, 8 memory nodes, and 4 routers.

     The cpus are:
     cpu   0 is /hw/module/1/slot/n1/node/cpu/a
     cpu   1 is /hw/module/1/slot/n1/node/cpu/b
     cpu   2 is /hw/module/1/slot/n2/node/cpu/a
     cpu   3 is /hw/module/1/slot/n2/node/cpu/b
     cpu   4 is /hw/module/1/slot/n3/node/cpu/a
     cpu   5 is /hw/module/1/slot/n3/node/cpu/b
     cpu   6 is /hw/module/1/slot/n4/node/cpu/a
     cpu   7 is /hw/module/1/slot/n4/node/cpu/b
     cpu   8 is /hw/module/2/slot/n1/node/cpu/a
     cpu   9 is /hw/module/2/slot/n1/node/cpu/b
     cpu  10 is /hw/module/2/slot/n2/node/cpu/a
     cpu  11 is /hw/module/2/slot/n2/node/cpu/b
     cpu  12 is /hw/module/2/slot/n3/node/cpu/a
     cpu  13 is /hw/module/2/slot/n3/node/cpu/b
     cpu  14 is /hw/module/2/slot/n4/node/cpu/a
     cpu  15 is /hw/module/2/slot/n4/node/cpu/b

     The nodes are:
     /hw/module/1/slot/n1/node
     /hw/module/1/slot/n2/node
     /hw/module/1/slot/n3/node
     /hw/module/1/slot/n4/node
     /hw/module/2/slot/n1/node
     /hw/module/2/slot/n2/node
     /hw/module/2/slot/n3/node
     /hw/module/2/slot/n4/node

     The routers are:
     /hw/module/1/slot/r1/router
     /hw/module/1/slot/r2/router
     /hw/module/2/slot/r1/router
     /hw/module/2/slot/r2/router

     The topology is defined by:



                                                                        Page 1
