Thanks for this information.  I’m hoping Alessandro (cc’d) will review and submit the Fortran 2015 EVENT patch that Tobias originally posted to this list in April:

https://gcc.gnu.org/ml/fortran/2015-04/msg00119.html

Given that Tobias’s email states the following, I hope this is a strong candidate for an exception to the stage rules if necessary:

 "I think the patch is finished, but I still have to extend the test cases, to re-read the patch and to write a changlog."

Alessandro submits his dissertation tomorrow (hooray!) and expects to resume work on gfortran/OpenCoarrays soon thereafter.   EVENT support already exists in OpenCoarrays so we are just waiting for support on the compiler side.  We are optimistic that judicious use of the EVENT features can have a positive impact on parallel performance as compared to SYNC ALL and SYNC IMAGES.

One important step Alessandro will need to take is to ensure that any recent changes to the relevant TS are reflected in the patch. It’s possibly there is nothing to do in that regard, but the good news is that the TS passed a straw ballot last month and is being forwarded to ISO for approval and publication so I think it’s safe to say that it is essentially final now.  That makes this a very opportune time to get the feature into the compiler.  

I don’t think anyone responded to Tobias’s April email.  I hope there is someone who is willing to review the patch when Alessandro or Tobias submits a candidate final version.
