You can not perform synchronization at the same time as communication on the
same target. This means if one thread is in MPI_Put/MPI_Get/MPI_Accumulate
(target) you can’t have another thread in MPI_Win_flush (target) or
MPI_Win_flush_all(). If your program is doing that it is not a valid MPI

All,
We are trying to combine MPI_Put and MPI_Win_flush on locked (using
MPI_Win_lock_all) dynamic windows to mimic a blocking put. The
application is (potentially) multi-threaded and we are thus relying on
MPI_THREAD_MULTIPLE support to be available.
When I try to use this combination (MPI_

Sure, this time I see more output (seems there was a typo in the env
variable earlier):

Joseph,
Would you mind trying again with
export OMPI_MCA_osc=^pt2pt
export OMPI_MCA_osc_base_verbose=10
If it still does not work, then please post the output
Cheers,

variables as you suggested but neither has any impact. The error message
stays the same with both env variables set. Is there any other way to
get more information from OpenMPI?
Sorry for not mentioning my OS. I'm r
