Hi all, I'd like to add counting feature to get the total number of message exchanges during one synchronization among BSP tasks. Before leave barrier in sync() method, each task can report their counts.
This information will be useful to user and, some applications (for example, the sync cost of current SSSP example can be reduced to 1/3). Should we add this feature? -- Best Regards, Edward J. Yoon @eddieyoon
