nodeinfo is normally created by our boot up stuff.  It looks something
like:

(node 0 (cpus 2)        (gm 10) (hz 2395000000) (mem 2119340032))       
(node 1 (cpus 2)        (gm 11) (hz 2395000000) (mem 2119340032))       
(node 2 (cpus 2)        (gm 12) (hz 2395000000) (mem 2119340032))       
(node 3 (cpus 2)        (gm 13) (hz 2395000000) (mem 2119340032))       
(node 4 (cpus 2)        (gm 14) (hz 2395000000) (mem 2119340032))       
(node 5 (cpus 2)        (gm 15) (hz 2395000000) (mem 2119340032))       
(node 6 (cpus 2)        (gm 16) (hz 2395000000) (mem 2119340032))       
(node 7 (cpus 2)        (gm 17) (hz 2395000000) (mem 2119340032))       
(node 8 (cpus 2)        (gm 18) (hz 2395000000) (mem 2119340032))       
(node 9 (cpus 2)        (gm 19) (hz 2395000000) (mem 2119340032))

These are all set by the mpirun that comes with cmtools.  NODES is
optional, the others are required if you're using that patch.
