| Research Abstract |
This research aims to develop a novel file cache algorithm suitable for many-core CPU environment that has many computation cores. The new method tries to cache high access cost data such as random accessed data that requires long time to be read from secondary storage devices. The evaluations by TPC-H, a de facto standard benchmark for DBMS, showed about five percent performance improvement on real computers. However, several dozen or several fold performance improvement enough for actual use was not achieved.
