+=head2 Signal, recurse and long job
+
+By default, OAR use signal USR2 for checkpointing.
+It's possible to change this with option C<--kill>>.
+
+When use with long small job, checkpointing could be too long...
+Option C<--transmit> could be use to checkpoint small job!
+These will then stop cleanly and will be restarted next time.
+
+In the C<logtrace> file, small job will have the status suspend.
+They will be launch with the same command next OAR run.
