/* NOTE: MPI-2.1 requires that MPI_FINALIZE is "collective" across
*all* connected processes. This only means that all processes
have to call it. It does *not* mean that all connected
processes need to synchronize (either directly or indirectly).
For example, it is quite easy to construct complicated
scenarios where one job is "connected" to another job via
transitivity, but have no direct knowledge of each other.
Consider the following case: job A spawns job B, and job B
later spawns job C. A "connectedness" graph looks something
like this:
A <--> B <--> C
So what are we *supposed* to do in this case? If job A is
still connected to B when it calls FINALIZE, should it block
until jobs B and C also call FINALIZE?
After lengthy discussions many times over the course of this
project, the issue was finally decided at the Louisville Feb
2009 meeting: no.
Rationale:
- "Collective" does not mean synchronizing. It only means that
every process call it. Hence, in this scenario, every
process in A, B, and C must call FINALIZE.
- KEY POINT: if A calls FINALIZE, then it is erroneous for B or
C to try to communicate with A again.
- Hence, OMPI is *correct* to only effect a barrier across each
jobs' MPI_COMM_WORLD before exiting. Specifically, if A
calls FINALIZE long before B or C, it's *correct* if A exits
at any time (and doesn't notify B or C that it is exiting).
- Arguably, if B or C do try to communicate with the now-gone
A, OMPI should try to print a nice error ("you tried to
communicate with a job that is already gone...") instead of
segv or other Badness. However, that is an *extremely*
difficult problem -- sure, it's easy for A to tell B that it
is finalizing, but how can A tell C? A doesn't even know
about C. You'd need to construct a "connected" graph in a
distributed fashion, which is fraught with race conditions,
etc.
Hence, our conclusion is: OMPI is *correct* in its current
behavior (of only doing a barrier across its own COMM_WORLD)
before exiting. Any problems that occur are as a result of
erroneous MPI applications. We *could* tighten up the erroneous
cases and ensure that we print nice error messages / don't
crash, but that is such a difficult problem that we decided we
have many other, much higher priority issues to handle that deal
with non-erroneous cases. */

For example: when a message arrives at the orted, we want the
OS to wake up the orted in a timely fashion (which most OS's
seem good about doing) and then we want the orted to process
the message as fast as possible. If the orted yields and lets
aggressive MPI applications get the processor back, it may be a
long time before the OS schedules the orted to run again
(particularly if there is no IO event to wake it up). Hence,
routed OOB messages (for example) may be significantly delayed
before being delivered to MPI processes, which can be
problematic in some scenarios (e.g., COMM_SPAWN, BTL's that

the message as fast as possible. If the orted yields and lets
aggressive MPI applications get the processor back, it may be a
long time before the OS schedules the orted to run again
(particularly if there is no IO event to wake it up). Hence,

/* NOTE: MPI-2.1 requires that MPI_FINALIZE is "collective" across
*all* connected processes. This only means that all processes
have to call it. It does *not* mean that all connected
processes need to synchronize (either directly or indirectly).
For example, it is quite easy to construct complicated
scenarios where one job is "connected" to another job via
transitivity, but have no direct knowledge of each other.
Consider the following case: job A spawns job B, and job B
later spawns job C. A "connectedness" graph looks something
like this:
A <--> B <--> C
So what are we *supposed* to do in this case? If job A is
still connected to B when it calls FINALIZE, should it block
until jobs B and C also call FINALIZE?
After lengthy discussions many times over the course of this
project, the issue was finally decided at the Louisville Feb
2009 meeting: no.
Rationale:
- "Collective" does not mean synchronizing. It only means that
every process call it. Hence, in this scenario, every
process in A, B, and C must call FINALIZE.
- KEY POINT: if A calls FINALIZE, then it is erroneous for B or
C to try to communicate with A again.
- Hence, OMPI is *correct* to only effect a barrier across each
jobs' MPI_COMM_WORLD before exiting. Specifically, if A
calls FINALIZE long before B or C, it's *correct* if A exits
at any time (and doesn't notify B or C that it is exiting).
- Arguably, if B or C do try to communicate with the now-gone
A, OMPI should try to print a nice error ("you tried to
communicate with a job that is already gone...") instead of
segv or other Badness. However, that is an *extremely*
difficult problem -- sure, it's easy for A to tell B that it
is finalizing, but how can A tell C? A doesn't even know
about C. You'd need to construct a "connected" graph in a
distributed fashion, which is fraught with race conditions,
etc.
Hence, our conclusion is: OMPI is *correct* in its current
behavior (of only doing a barrier across its own COMM_WORLD)
before exiting. Any problems that occur are as a result of
erroneous MPI applications. We *could* tighten up the erroneous
cases and ensure that we print nice error messages / don't
crash, but that is such a difficult problem that we decided we
have many other, much higher priority issues to handle that deal
with non-erroneous cases. */
/* Wait for everyone to reach this point. This is a grpcomm
barrier instead of an MPI barrier for (at least) two reasons:
1. An MPI barrier doesn't ensure that all messages have been
transmitted before exiting (e.g., a BTL can lie and buffer a
message without actually injecting it to the network, and
therefore require further calls to that BTL's progress), so
the possibility of a stranded message exists.
2. If the MPI communication is using an unreliable transport,
there's a problem of knowing that everyone has *left* the
barrier. E.g., one proc can send its ACK to the barrier
message to a peer and then leave the barrier, but the ACK
can get lost and therefore the peer is left in the barrier.
Point #1 has been known for a long time; point #2 emerged after
we added the first unreliable BTL to Open MPI and fixed the
del_procs behavior around May of 2014 (see
https://svn.open-mpi.org/trac/ompi/ticket/4669#comment:4 for
more details). */
