AMRZone: A Runtime AMR Data Sharing Framework for Scientific Applications

Zhang, W., Tang, H., Harenberg, S., Byna, S., Zou, X., Devendran, D., … Samatova, N. F. (2016, May 1).

By: W. Zhang n, H. Tang n, S. Harenberg n, S. Byna *, X. Zou n, D. Devendran*, D. Martin *, K. Wu * ...

topics (OpenAlex): Advanced Data Storage Technologies; Data Management and Algorithms; Distributed and Parallel Computing Systems
TL;DR: AMRZone's performance and scalability are even comparable with existing state-of-the-art work when tested over uniform mesh data with up to 16384 cores, in the best case, the framework achieves a 46% performance improvement. (via Semantic Scholar)

Exploring memory hierarchy and network topology for runtime AMR data sharing across scientific applications

Zhang, W., Tang, H., Ranshous, S., Byna, S., Martin, D. F., Wu, K., … Samatova, N. F. (2016, December 1).

By: W. Zhang n, H. Tang *, S. Ranshous n, S. Byna *, D. Martin *, K. Wu *, B. Dong *, S. Klasky*, N. Samatova n

topics (OpenAlex): Advanced Data Storage Technologies; Distributed and Parallel Computing Systems; Parallel Computing and Optimization Techniques
TL;DR: Results show the proposed framework's spatial access pattern detection and prefetching methods demonstrate about 26% performance improvement for client analytical processes and the framework's topology-aware data placement can improve overall data access performance by up to 18%.

In Situ Storage Layout Optimization for AMR Spatio-temporal Read Accesses

Tang, H., Byna, S., Harenberg, S., Zhang, W., Zou, X., Martin, D. F., … Samatova, N. F. (2016, August 1).

By: H. Tang n, S. Byna *, S. Harenberg n, W. Zhang n, X. Zou n, D. Martin *, B. Dong *, D. Devendran* ...

topics (OpenAlex): Advanced Data Storage Technologies; Simulation Techniques and Applications; Computer Graphics and Visualization Techniques
TL;DR: This work develops an in situ data layout optimization framework that automatically selects from a set of candidate layouts based on a performance model, and reorganizes the data before writing to storage to enable efficient AMR read accesses. (via Semantic Scholar)

Usage Pattern-Driven Dynamic Data Layout Reorganization

Tang, H., Byna, S., Harenberg, S., Zou, X., Zhang, W., Wu, K., … Samatova, N. F. (2016, May 1).

By: H. Tang n, S. Byna *, S. Harenberg n, X. Zou n, W. Zhang n, K. Wu *, B. Dong *, O. Rubel * ...

topics (OpenAlex): Advanced Data Storage Technologies; Parallel Computing and Optimization Techniques; Advanced Database Systems and Queries
TL;DR: This work proposes a framework that dynamically recognizes the data usage patterns, replicates the data of interest in multiple reorganized layouts that would benefit common read patterns, and makes runtime decisions on selecting a favorable layout for a given read pattern.
