\fIopal-checkpoint\fR will attempt to notify a running process that it has been

requested that the process checkpoint itself. A snapshot handle reference is

presented to the user, which is used in \fIopal_restart\fP to restart the

process.

.SH DESCRIPTION
|
|
.
|
|
.PP
|
|
\fIopal-checkpoint\fR can be invoked multiple, non-overlapping times. This
|
|
allows the user to take involuntary checkpoints of a running sequential
|
|
process. See opal_crs(7) for more information about the CRS framework and
|
|
components. 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 the
|
|
running process being checkpointed.
