DESCRIPTION

16       A MPI application can be restarted using lamrestart.
17
18       lamrestart calls the module-specific restart function.  If the selected
19       SSI module is
20        'self', the SSI parameter specifying the arguments to be passed to
21       mpirun should also be given as an argument to lamrestart.  In case the
22       'blcr' Checkpoint/Restart module is specified as the 'cr' SSI parame‐
23       ter, the location of the context file should be passed as an argument
24       to lamrestart.
25

EXAMPLES

27       lamrestart -ssi cr self -ssi cr_restart_args "-ssi cr_self_prefix foo
28       -np 2 /location/of/application"
29           Restart application on 2 nodes.  Note that it is assumed that the
30           application has a function named 'foo_restart', failing which
31           mpirun aborts.
32
33       lamrestart -ssi cr blcr -ssi cr_blcr_context_file /path/to/context/file
34           Restart mpirun using the specified context file.  The context file
35           is the file that was saved during checkpoint time.
