Very interesting. But I was really surprised that the conclusions didn't mention any performance results. The problem description in the abstract states that "Past analysis shows that big-memory workloads can spend 5%-50%of execution cycles on TLB misses". I somehow expected that they would have presented some before and after-performance results. In Conclusion they state that "Our preliminary results show that the TLB-Miss overheadhas reduced significantly and we plan to do further analysis onwhere to perform the Direct Segment lookup in hardware to get thebest performance." So I guess they had a dealine to meet.
