Dear Wiki user, You have subscribed to a wiki page or wiki category on "Hama Wiki" for change notification.
The "Benchmarks" page has been changed by edwardyoon: https://wiki.apache.org/hama/Benchmarks?action=diff&rev1=64&rev2=65 ||60M || 40 seconds || 50 seconds || ||30M || 28 seconds || 40 seconds || + What are the major changes from the last release? + + The major improvement changes are in the queue and messaging systems. We now use own outgoing/incoming message manager instead of using Java's built-in queues. It stores messages in serialized form in a set of bundles (or a single bundle) to reduce the memory usage and RPC overhead. Kryo serializer is used to serialize objects more quickly. Another important improvement is the enhanced graph package. Instead of sending each message individually, we package the messages per vertex and send a packaged message to their assigned destination nodes. The thread-pool executor service also used for each vertex computation. With this, we achieve better performance. == Graph Package: PageRank Benchmarks 0.6.4 vs 0.7.0-SNAPSHOT ==
