Gilles,
Sure, this time I see more output (seems there was a typo in the env
variable earlier):
```
$ echo $OMPI_MCA_osc
^pt2pt
$ echo $OMPI_MCA_osc_base_verbose
10
$ mpirun -n 2 ./a.out
[beryl:12905] mca: base: components_register: registering framework osc
components
[beryl:12904] mca: base
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,
Gilles

Hi Howard,
Thanks for your quick reply and your suggestions. I exported both
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
Hi Joseph
What OS are you using when running the test?
Could you try running with
export OMPI_mca_osc=^pt2pt
and
export OMPI_mca_osc_base_verbose=10
This error message was put in to this OMPI release because this part of the
code has known problems when used multi threaded.

All,
I am seeing a fatal error with OpenMPI 2.0.2 if requesting support for
MPI_THREAD_MULTIPLE and afterwards creating a window using
MPI_Win_create. I am attaching a small reproducer. The output I get is
the following:
```
MPI_THREAD_MULTIPLE supported: yes
MPI_THREAD_MULTIPLE supported: y
