LAMRESTART(1) LAM COMMANDS LAMRESTART(1)
NAME
lamrestart - restart a LAM/MPI program.
SYNOPSIS
lamrestart -ssi cr self|blcr -ssi cr_restart_args argstompirun -ssi
cr_blcr_context_file contextfile
OPTIONS
-h Print useful information on this command.
DESCRIPTION
A MPI application can be restarted using lamrestart.
lamrestart calls the module-specific restart function. If the selected
SSI module is
'self', the SSI parameter specifying the arguments to be passed to
mpirun should also be given as an argument to lamrestart. In case the
'blcr' Checkpoint/Restart module is specified as the 'cr' SSI
parameter, the location of the context file should be passed as an
argument to lamrestart.
EXAMPLES
lamrestart -ssi cr self -ssi cr_restart_args "-ssi cr_self_prefix foo
-np 2 /location/of/application"
Restart application on 2 nodes. Note that it is assumed that the
application has a function named 'foo_restart', failing which
mpirun aborts.
lamrestart -ssi cr blcr -ssi cr_blcr_context_file /path/to/context/file
Restart mpirun using the specified context file. The context file
is the file that was saved during checkpoint time.
