…_ADDR_UNSPEC There was a bug where if the source address was FI_ADDR_UNSPEC the context matching function used for processing queues and fifos did not look at the tag and successfully matched, resulting in hangs around MPI_Recv. The logic was changed to always look at both the tag and source addr when making a match. Signed-off-by: Paul Coffman <pcoffman@anl.gov>

I added @pkcoff as a writer to this repo. Paul, you should be able to merge your own changes to the bgq provider now. We only ask that you let us know if any patches touch the code outside of the provider. Thanks! |
