Today, I tested all Hama examples on my cluster of 32 nodes, with 96 tasks. Pi and Serialized Printing examples were working fine but
1. Barrier Synchronizations are not working well (with a 'bench' example). 2. When an unexpected shutdown occurs, ZK nodes (which created by each BSPPeer) will not be deleted. There's no way to clean them up before reboot the server. 3. Graph examples are not working. 4. Too many reporting times between Groom and Master. 5. And, there are many code issues that can be improved. 1, and 2 issues are already reported (See HAMA-387, HAMA-407). Some of 3, 4, and 5 issues are already started by ChiaHung Lin. All issues around this should be fixed in HAMA-413? or, Should we just commit HAMA-413? Thanks. -- Best Regards, Edward J. Yoon @eddieyoon
