   Node Specification
       Target  nodes  are  given  on  the command line.  Nodes are generically
       identified as n<list>, where <list> can be a single node identifier  or
       a list of node identifiers.  For example:


       Additionally,  c<list>  can  be  used  to list specific CPUs on a given
       machine (lamboot(1) is used to specify how many CPUs  LAM  may  use  on
       each node).

       Node/CPU identifiers are established in the boot schema (see bhost(5)),
       and can be written in decimal or hexadecimal notation.  In addition  to
       explicit  node  identification, LAM has special mnemonics that refer to
       special nodes or a group of nodes.

       h       the local node where the command is typed (as in "here")

       o       the origin node where LAM was started with lamboot(1)

       N       all nodes

       C       all CPUs

   Process Specification
       LAM processes can be specified in two ways: by process identifier  from
       the  underlying  operating  system  or  by LAM process index.  PIDs are
       written as p<list>, where <list> can be a single PID or a list of PIDs.
       Process  indices  are  written as i<list>, where <list> can be a single
       index or a list of indices.
