This paper describes an empirical study designed to quantify the level of cross-loop reuse occurring in a set of scientiic Fortran programs, the NAS Benchmarks. Cross-loop reuse takes place when a set of data items or cache lines are accessed in a given loop nest and then accessed again within some subsequent portion of the program (usually another outer loop nest). In contrast to intra-loop re...

This paper presents a study of the performance limits of data value reuse. Two types of data value reuse are considered: instruction-level reuse and trace-level reuse. The former reuses instances of single instructions whereas the latter reuses sequences of instructions as an atomic unit. Two different scenarios are considered: an infinite resource machine and a machine with a limited instructi...

Question Answering (QA) is an emerging important field in Information Retrieval. In a QA system the archive of previous questions asked from the system makes a collection full of useful factual nuggets. This paper makes an initial attempt to investigate the reuse of facts contained in the archive of previous questions to help and gain performance in answering future related factoid questions. I...
