       -v      Be verbose.


DESCRIPTION

       The lamclean command attempts to remove all user processes
       and messages from all nodes.   It  also  de-allocates  all
       user allocated resources and cancels all user process reg­
       istrations.   This  happens  by  invoking  many  different
       remote  services  which have previously been invoked indi­
       vidually by several other commands.  These commands should
       still be used when partial selective removal of user pres­
       ence is desired.  Otherwise, lamclean is a quick and  con­
       venient  way  of starting over after a bad application run
       without rebooting the system.

       lamclean takes the following actions on the following sys­
       tem processes on all nodes:

       kenyad         The  LAM SIGUDIE signal (terminate) is sent
                      to all user processes.  See doom(1).

       bufferd        The entire daemon is reset to  its  initial
                      state after booting.  See sweep(1).

       filed          All  user file descriptors are closed.  See
                      fctl(1).

       traced         All traces are removed.  See lamtrace(1).

       lamclean will not succeed if any of the nodes are unreach­
       able  due  to catastrophic failure or maximum buffer over­
       flow with link jamming.  If lamclean does not return,  use
       wipe(1) and lamboot(1) to restart the multicomputer.
