Halting lamd

LAM 6.5.9/MPI 2 C++/ROMIO - Indiana University

-----------------------------------------------------------------------------
It seems that there is no lamd running on this host, which indicates
that the LAM/MPI runtime environment is not operating.  The LAM/MPI
runtime environment is necessary for the "lamhalt" command.

Please run the "lamboot" command the start the LAM/MPI runtime
environment.  See the LAM/MPI documentation for how to invoke
"lamboot" across multiple machines.
