J3/06-321 Date: 24 October 2006 To: J3 From: Bill Long and John Reid Subject: Issue 63, FORM_TEAM synchronization Reference: J3/06-007r1, J3/06-266 Discussion of issue 63 (page 380) FORM_TEAM is a collective routine so that an implementation has the option of performing operations that involve all the team members. For example, the times for trial round trip messages to the other images might be used to determine an optimal communication pattern for the team. SYNC_IMAGES involves a different form of synchronization. In particular, the image sets may vary between the images involved. This may allow better load balancing than would be possible with SYNC_TEAM. Edit to J3/06-007r1 None.
