Tasks may belong to task groups where each group may have a different priority. In that case, tasks are prioritized by group… Continue reading Resource aware queue

As everything is in-memory you maintain… Continue reading Oracle Coherence and MapReduce

It was kind of dated and as the Java VM continues to improve (in addition to the C++ compiler I would presume), I thought it would be interesting to rerun the tests to see what we would end up with. So this is what I… Continue reading C++ vs Java performance; It’s a tie!
