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

              n1
              n1,3,5-10

       Additionally, clist 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 plist, where list can be a single  PID  or  a  list  of  PIDs.
       Process indices are written as ilist, where list can be a single index or a list of indices.
