OPAL_CRS \- Open PAL MCA Checkpoint/Restart Service (CRS): Overview of Open PAL's
CRS framework, and selected modules. Open MPI 4.0.1.
.
.\" **************************
.\" Description Section
.\" **************************
.SH DESCRIPTION
.
.PP
Open PAL can involuntarily checkpoint and restart sequential programs.
Doing so requires that Open PAL was compiled with thread support and
that the back-end checkpointing systems are available at run-time.
.
.SS Phases of Checkpoint / Restart
.PP
Open PAL defines three phases for checkpoint / restart support in a
procress:
.
.TP 4
Checkpoint
When the checkpoint request arrives, the procress is notified of the
request before the checkpoint is taken.
.
.TP 4
Continue
After a checkpoint has successfully completed, the same process as the
checkpoint is notified of its successful continuation of execution.
.
.TP 4
Restart
After a checkpoint has successfully completed, a new / restarted
process is notified of its successful restart.
.
.PP
The Continue and Restart phases are identical except for the process
in which they are invoked. The Continue phase is invoked in the same process
as the Checkpoint phase was invoked. The Restart phase is only invoked in newly
restarted processes.
.
.\" **************************
.\" General Process Requirements Section
.\" **************************
.SH GENERAL PROCESS REQUIREMENTS
.PP
In order for a process to use the Open PAL CRS components it must adhear to a
few programmatic requirements.
.PP
First, the program must call \fIOPAL_INIT\fR early in its execution. This
should only be called once, and it is not possible to checkpoint the process
without it first having called this function.
.PP
The program must call \fIOPAL_FINALIZE\fR before termination. This does a
significant amount of cleanup. If it is not called, then it is very likely that
remnants are left in the filesystem.
.PP
To checkpoint and restart a process you must use the Open PAL tools to do
so. Using the backend checkpointer's checkpoint and restart tools will lead
to undefined behavior.
To checkpoint a process use \fIopal_checkpoint\fR (opal_checkpoint(1)).
To restart a process use \fIopal_restart\fR (opal_restart(1)).
.
.\" **********************************
.\" Available Components Section
.\" **********************************
.SH AVAILABLE COMPONENTS
.PP
Open PAL ships with two CRS components: \fIself\fR and \fIblcr\fR.
.
.PP
The following MCA parameters apply to all components:
.
.TP 4
crs_base_verbose
Set the verbosity level for all components. Default is 0, or silent except on error.
.
.\" Self Component
.\" ******************
.SS self CRS Component
.PP
The \fIself\fR component invokes user-defined functions to save and restore
checkpoints. It is simply a mechanism for user-defined functions to be invoked
at Open PAL's Checkpoint, Continue, and Restart phases. Hence, the only data
that is saved during the checkpoint is what is written in the user's checkpoint
function. No libary state is saved at all.
.
.PP
As such, the model for the \fIself\fR component is slightly differnt than for
other components. Specifically, the Restart function is not invoked in the same
process image of the process that was checkpointed. The Restart phase is
invoked during \fBOPAL_INIT\fR of the new instance of the applicaiton (i.e., it
starts over from main()).
.
.PP
The \fIself\fR component has the following MCA parameters:
.TP 4
crs_self_prefix
Speficy a string prefix for the name of the checkpoint, continue, and restart
functions that Open PAL will invoke during the respective stages. That is,
by specifying "-mca crs_self_prefix foo" means that Open PAL expects to find
three functions at run-time:
int foo_checkpoint()
int foo_continue()
int foo_restart()
By default, the prefix is set to "opal_crs_self_user".
.
.TP 4
crs_self_priority
Set the \fIself\fR components default priority
.
.TP 4
crs_self_verbose
Set the verbosity level. Default is 0, or silent except on error.
.
.TP 4
crs_self_do_restart
This is mostly internally used. A general user should never need to set this
value. This is set to non-0 when a the new process should invoke the restart
callback in \fIOPAL_INIT\fR. Default is 0, or normal execution.
.

crs_blcr_priority
Set the \fIblcr\fR components default priority.
.
.TP 4
crs_blcr_verbose
Set the verbosity level. Default is 0, or silent except on error.

ORTE_HOSTS \- OpenRTE Hostfile and HOST Behavior: Overview of OpenRTE's support for user-supplied
hostfiles and comma-delimited lists of hosts
.
.\" **************************
.\" Description Section
.\" **************************
.SH DESCRIPTION
.
.PP
OpenRTE supports several levels of user-specified host lists based on an established
precedence order. Users can specify a \fIdefault hostfile\fP that contains a list of
nodes available to all app_contexts given on the command line. Only \fIone\fP default
hostfile can be provided for any job. In addition, users
can specify a \fIhostfile\fP that contains a list of nodes to be used for a specific
app_context, or can provide a comma-delimited list of nodes to be used for that
app_context via the \fI-host\fP command line option.
.sp
The precedence order applied to these various options depends to some extent on
the local environment. The following table illustrates how host and hostfile directives
work together to define the set of hosts upon which a job will execute
in the absence of a resource manager (RM):
.sp
.nf
default
hostfile host hostfile Result
---------- ------ ---------- -----------------------------------------
unset unset unset Job is co-located with mpirun
unset set unset Host defines resource list for the job
unset unset set Hostfile defines resource list for the job
unset set set Hostfile defines resource list for the job,
then host filters the list to define the final
set of nodes available to each application
within the job
set unset unset Default hostfile defines resource list for the job
set set unset Default hostfile defines resource list for the job,
then host filters the list to define the final
set of nodes available to each application
within the job
set set set Default hostfile defines resource list for the job,
then hostfile filters the list, and then host filters
the list to define the final set of nodes available
to each application within the job
.fi
.sp
This changes somewhat in the presence of a RM as that entity specifies the
initial allocation of nodes. In this case, the default hostfile, hostfile and host
directives are all used to filter the RM's specification so that a user can utilize different
portions of the allocation for different jobs. This is done according to the same precedence
order as in the prior table, with the RM providing the initial pool of nodes.
.sp
.
.\" **************************
.\" Relative Indexing
.\" **************************
.SH RELATIVE INDEXING
.
.PP
Once an initial allocation has been specified (whether by an RM, default hostfile, or hostfile),
subsequent hostfile and -host specifications can be made using relative indexing. This allows a
user to stipulate which hosts are to be used for a given app_context without specifying the
particular host name, but rather its relative position in the allocation.
.sp
This can probably best be understood through consideration of a few examples. Consider the case
where an RM has allocated a set of nodes to the user named "foo1, foo2, foo3, foo4". The user
wants the first app_context to have exclusive use of the first two nodes, and a second app_context
to use the last two nodes. Of course, the user could printout the allocation to find the names
of the nodes allocated to them and then use -host to specify this layout, but this is cumbersome
and would require hand-manipulation for every invocation.
.sp
A simpler method is to utilize OpenRTE's relative indexing capability to specify the desired
layout. In this case, a command line of:
.sp
mpirun -pernode -host +n1,+n2 ./app1 : -host +n3,+n4 ./app2
.sp
.PP
would provide the desired pattern. The "+" syntax indicates that the information is being
provided as a relative index to the existing allocation. Two methods of relative indexing
are supported:
.sp
.TP
.B +n<#>
A relative index into the allocation referencing the <#> node. OpenRTE will substitute
the <#> node in the allocation
.
.
.TP
.B +e[:<#>]
A request for <#> empty nodes - i.e., OpenRTE is to substitute this reference with
<#> nodes that have not yet been used by any other app_context. If the ":<#>" is not
provided, OpenRTE will substitute the reference with all empty nodes. Note that OpenRTE
does track the empty nodes that have been assigned in this manner, so multiple
uses of this option will result in assignment of unique nodes up to the limit of the
available empty nodes. Requests for more empty nodes than are available will generate
an error.
.sp
.PP
Relative indexing can be combined with absolute naming of hosts in any arbitrary manner,
and can be used in hostfiles as well as with the -host command line option. In addition,
any slot specification provided in hostfiles will be respected - thus, a user can specify
that only a certain number of slots from a relative indexed host are to be used for a
given app_context.
.sp
Another example may help illustrate this point. Consider the case where a user has a default
hostfile containing:
.sp
.nf
dummy1 slots=4
dummy2 slots=4
dummy3 slots=4
dummy4 slots=4
dummy5 slots=4
.fi
.sp
.PP
This may, for example, be a hostfile that describes a set of commonly-used resources that
the user wishes to execute applications against. For this particular application, the user
plans to map byslot, and wants the first two ranks to be on the second node of any allocation,
the next ranks to land on an empty node, have one rank specifically on dummy4, the next rank
to be on the second node of the allocation again, and finally any remaining ranks to be on
whatever empty nodes are left. To accomplish this, the user provides a hostfile of:
.sp
.nf
+n2 slots=2
+e:1
dummy4 slots=1
+n2
+e
.fi
.sp
.PP
The user can now use this information in combination with OpenRTE's sequential mapper to
obtain their specific layout:
.sp
.nf
mpirun --default-hostfile dummyhosts -hostfile mylayout -mca rmaps seq ./my_app
.fi
.sp
.PP
which will result in:
.nf
.sp
rank0 being mapped to dummy3
.br
rank1 to dummy1 as the first empty node
.br
rank2 to dummy4
.br
rank3 to dummy3
.br
rank4 to dummy2 and rank5 to dummy5 as the last remaining unused nodes
.sp
.fi
Note that the sequential mapper ignores the number of slots arguments as it only
maps one rank at a time to each node in the list.
.sp
If the default round-robin mapper had been used, then the mapping would have resulted in:
.sp
.nf
ranks 0 and 1 being mapped to dummy3 since two slots were specified
.br
ranks 2-5 on dummy1 as the first empty node, which has four slots
.br
rank6 on dummy4 since the hostfile specifies only a single slot from that node is to be used
.br
ranks 7 and 8 on dummy3 since only two slots remain available
.br
ranks 9-12 on dummy2 since it is the next available empty node and has four slots
.br
ranks 13-16 on dummy5 since it is the last remaining unused node and has four slots
.fi
.sp
.PP
Thus, the use of relative indexing can allow for complex mappings to be ported across
allocations, including those obtained from automated resource managers, without the need
for manual manipulation of scripts and/or command lines.
