Scrambler: dynamic layout adaptation

Content Provider ACM Digital Library
Author Chang, David Takayesu, Niko Nguyen, Thu
Abstract Developers and compiler writers spend significant effort on performance tuning and optimizations. However, the impact of these efforts must be taken with a grain of salt. Prior work has shown that changes to a program's layout—the placement of code and data in memory—can change performance by more than the effect of standard optimization techniques. This paper presents Scrambler, a system that dynamically changes the layout of programs to improve their performance. Scrambler runs C and C++ programs with a randomized layout, and monitors these programs for evidence of layout-related performance issues. When an issue is detected, Scrambler relocates the offending code to eliminate the layout issue. We evaluate Scrambler on eight SPEC CPU2006 benchmarks, and find that Scrambler can provide speedups as large as 4.6% by fixing layouts that hurt branch predictor performance. These early results are encouraging, and we plan to extend this work to support additional layout-related performance issues in the future. .

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
