- My original patch stands: MPI_FINALIZE directly invokes the
attribute callbacks on MPI_COMM_SELF
- We added some user-level checks to ensure that they don't call
MPI_FINALIZE twice (this isn't really required, but it will prevent
whacky segv's -- they'll at least get a nice error message)
- Removed the attribute callbacks on MPI_COMM_SELF from
ompi_mpi_comm_finalize (i.e., we just moved them from
ompi_mpi_comm_finalize to ompi_mpi_finalize -- we just moved this
process up earlier in the MPI_FINALIZE sequence of events)
- Because there were so many conversations about this, here's the
rationale:
- MPI-2:4.8 says that we have to MPI_COMM_FREE MPI_COMM_SELF so that
the attribute callbacks are invoked.
- After considerable discussion, we came to the conclusion that
FREE'ing COMM_SELF is not the issue -- calling the callbacks is
the issue.
- So it is sufficent for MPI_FINALIZE to directly invoke these
attribute callbacks
- The attribute callbacks are *not* invoked on other communicators
because said communicators are not MPI_COMM_FREE'ed

[mpi_init:startup:internal-failure]
|
|
It looks like %s failed for some reason; your parallel process is
|
|
likely to abort. There are many reasons that a parallel process can
|
|
fail during %s; some of which are due to configuration or environment
|
|
problems. This failure appears to be an internal failure; here's some
|
|
additional information (which may only be relevant to an Open MPI
|
|
developer):

[mpi-param-check-enabled-but-compiled-out]
|
|
WARNING: The MCA parameter mpi_param_check has been set to true, but
|
|
parameter checking has been compiled out of Open MPI. The
|
|
mpi_param_check value has therefore been ignored.
|
|
[mpi_init:startup:paffinity-unavailable]
|
|
The MCA parameter "mpi_paffinity_alone" was set to a nonzero value,
|
|
but Open MPI was unable to bind MPI_COMM_WORLD rank %s to a processor.
|
|
|
|
Typical causes for this problem include:
|
|
|
|
- A node was oversubscribed (more processes than processors), in
|
|
which case Open MPI will not bind any processes on that node
|
|
- A startup mechanism was used which did not tell Open MPI which
|
|
processors to bind processes to
|
|
[mpi_finalize:invoked_multiple_times]
|
|
The function MPI_FINALIZE was invoked multiple times in a single
|
|
process on host %s, PID %d.
|
|
|
|
This indicates an erroneous MPI program; MPI_FINALIZE is only allowed
|
|
to be invoked exactly once in a process.
