tkill tkill.1 Terminate local node LAM session.
tping tping.1 Echo messages to a node.
wipe wipe.1 Terminate LAM.
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:
n1
n1,3,5-10
Node 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
C
all nodes intended for application computing
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.
