\fIorte-checkpoint\fR will attempt to notify a running parallel job (identified
|

|
by \fImpirun\fP) that it has been requested that the job checkpoint itself. A
|

|
|
global snapshot handle reference is presented to the user, which is used in
|
||
|
|
\fIompi_restart\fP to restart the job.

.SH DESCRIPTION
|
||
|
|
.
|
||
|
|
.PP
|
||
|
|
\fIorte-checkpoint\fR can be invoked multiple, non-overlapping times.
|
||
|
|
It is convenient to note that the user does not need to spectify
|
||
|
|
the checkpointer to be used here, as that is determined completely by each of
|
||
|
|
the running process in the job being checkpointed.
