J3/15-201 To: J3 From: R. Bader Subject: DE6 comment on TS18508 Date: 2015 August 05 Reference: N2056, N2066 DISCUSSION: The response to the DE6 comment was that [20:8-9] was put in to enable an implementation to perform additional optimizations in case the actual argument could be determined to be a coarray. This paper suggests adding some text to NOTE 8.4 to describe the motivation.. EDITS: Add following new paragraph at the end of NOTE 8.4: "If the actual argument is a coarray, the implementation might be able to optimize the execution of the collective, for example by avoiding copying of data."
