A Scalable Gaussian Process Approach to Shear Mapping with MuyGPs

Autor: Sallaberry, Gregory, Priest, Benjamin W., Armstrong, Robert, Schneider, Michael D., Muyskens, Amanda, Steil, Trevor, Iwabuchi, Keita

Analysis of cosmic shear is an integral part of understanding structure growth across cosmic time, which in-turn provides us with information about the nature of dark energy. Conventional methods generate \emph{shear maps} from which we can infer the

Metall: A Persistent Memory Allocator For Data-Centric Analytics

Autor: Iwabuchi, Keita, Youssef, Karim, Velusamy, Kaushik, Gokhale, Maya, Pearce, Roger

Data analytics applications transform raw input data into analytics-specific data structures before performing analytics. Unfortunately, such data ingestion step is often more expensive than analytics. In addition, various types of NVRAM devices are

TriPoll: Computing Surveys of Triangles in Massive-Scale Temporal Graphs with Metadata

Autor: Steil, Trevor, Reza, Tahsin, Iwabuchi, Keita, Priest, Benjamin W., Sanders, Geoffrey, Pearce, Roger

Understanding the higher-order interactions within network data is a key objective of network science. Surveys of metadata triangles (or patterned 3-cycles in metadata-enriched graphs) are often of interest in this pursuit. In this work, we develop T

UMap: Enabling Application-driven Optimizations for Page Management

Autor: Peng, Ivy B., McFadden, Marty, Green, Eric, Iwabuchi, Keita, Wu, Kai, Li, Dong, Pearce, Roger, Gokhale, Maya

Leadership supercomputers feature a diversity of storage, from node-local persistent memory and NVMe SSDs to network-interconnected flash memory and HDD. Memory mapping files on different tiers of storage provides a uniform interface in applications.
