(j3.2006) (SC22WG5.5060) [ukfortran] WG5 vote on draft TS on further coarray features

[Lionel, Steve]

Here is my vote - I'm not taking a position on the other issues being discussed on the list right now.


Please answer the following question "Is N1983 ready for forwarding to
SC22 as the DTS?" in one of these ways.

2) Yes, but I recommend the following changes.

On page 11, R507 "form-team-spec" should be "form-subteam-spec" (probably left over from an older draft)

Events - I'd like to see a note or some wording specifying what happens if more than one image is waiting for an event to be posted. Say images 2 and 3 are sitting at an EVENT_WAIT with the event count at 0. Image 1 calls EVENT_POST once for the event. Do both images 2 and 3 proceed? I hope not, but I don't see anything to suggest one way or the other. (Perhaps also wording saying that if more than one image is waiting, the order in which they are released is implementation-dependent.)

7.4.1 (ATOMIC_ADD) - change "ATOM becomes defined with the value of ATOM + VALUE." To "ATOM becomes defined with the value of ATOM + INT(VALUE,ATOMIC_INT_KIND)."   Or is the intent that the normal mixed-mode arithmetic and assignment rules apply? This seems rather ugly to me, and "becomes defined with the value" is not intrinsic assignment.
