2015 article

Parallel In Situ Detection of Connected Components in Adaptive Mesh Refinement Data

2015 15TH IEEE/ACM INTERNATIONAL SYMPOSIUM ON CLUSTER, CLOUD AND GRID COMPUTING, pp. 302–312.

By: X. Zou n, K. Wu*, D. Boyuka n, D. Martin*, S. Byna*, H. Tang n, K. Bansal n, T. Ligocki*, H. Johansen*, N. Samatova n

TL;DR: The first connected component detection methodology for structured AMR that is applicable in a parallel, in situ context is presented, incorporating an multi-phase AMR-aware communication pattern that synchronizes connectivity information across the AMR hierarchy. (via Semantic Scholar)

2015 article

The Hyperdyadic Index and Generalized Indexing and Query with PIQUE

PROCEEDINGS OF THE 27TH INTERNATIONAL CONFERENCE ON SCIENTIFIC AND STATISTICAL DATABASE MANAGEMENT.

By: D. Boyuka n, H. Tang n, K. Bansal n, X. Zou n, S. Klasky* & N. Samatova n

TL;DR: PIQUE factors out commonalities in indexing, employing algorithmic/data structure "plugins" to mix orthogonal indexing concepts such as FastBit compressed bitmaps with ALACRITY binning, all within one framework. (via Semantic Scholar)

DIRAQ: scalable in situ data- and resource-aware indexing for optimized query performance

CLUSTER COMPUTING-THE JOURNAL OF NETWORKS SOFTWARE TOOLS AND APPLICATIONS, 17(4), 1101–1119.

By: S. Lakshminarasimhan n, X. Zou n, D. Boyuka n, S. Pendse n, J. Jenkins n, V. Vishwanath*, M. Papka*, S. Klasky*, N. Samatova n

author keywords: Exascale computing; Indexing; Query processing; Compression
TL;DR: DIRAQ is proposed, a parallel in situ, in network data encoding and reorganization technique that enables the transformation of simulation output into a query-efficient form, with negligible runtime overhead to the simulation run. (via Semantic Scholar)

2012 conference paper

Byte-precision level of detail processing for variable precision analytics

International conference for high performance computing networking.

By: J. Jenkins n, E. Schendel n, S. Lakshminarasimhan n, D. Boyuka n, T. Rogers n, S. Ethier*, R. Ross*, S. Klasky*, N. Samatova n

TL;DR: A precision level of detail (APLOD) library is developed, which partitions double-precision datasets along user-defined byte boundaries, and finds a strong applicability for the use of varying degrees of precision to reduce the cost of analyzing extreme-scale data. (via Semantic Scholar)
