[OMPI users] OSC UCX error using MPI_Win_allocate

[Stephen Guzik via users]

Hi,

For development purposes, I built and installed Open MPI 5.0.2 on my 
workstation.  As I understand it, to use OpenSHMEM, one has to include 
ucx.  I configured with

./configure --build=x86_64-linux-gnu 
--prefix=/usr/local/openmpi/5.0.2_gcc-12.2.0 --with-ucx 
--with-pmix=internal --with-libevent=external --with-hwloc=external 
--enable-mpi-fortran=all --with-cuda=/usr/local/cuda 
--with-cuda-libdir=/usr/lib/x86_64-linux-gnu

All seems fine with both MPI and OpenSHMEM until I try to use 
MPI_Win_allocate in which case I see the following error, once for each 
call:

osc_ucx_component.c:369  Error: OSC UCX component priority set inside 
component query failed

While the job still seems to run correctly, any advice on removing the 
error?

Thanks,
Stephen
