Annette Greiner is a data nerd with particular interest in interaction design and visualization. She came to NERSC upon completion of a Master's in Information Management and Systems from UC Berkeley's School of Information, with a focus on human-computer interaction. Before returning to school, she developed web sites for the Advanced Light Source and the DOE Joint Genome Institute. At NERSC, her duties include wrangling data and developing science gateways of all kinds. At a broader level, she represents the Laboratory to the World Wide Web Consortium (W3C) and has served on international working groups related to publication and sharing of data. Her interests touch the UC Berkeley campus as well, where she teaches data visualization for the Master's in Information and Data Science (MIDS) program at the School of Information. Annette also holds a B.S. in biomedical science and theater from the University of Michigan.

As microbiome research becomes increasingly prevalent in the fields of human health, agriculture and biotechnology, there exists a need for a resource to better link organisms and environmental chemistries. Exometabolomics experiments now provide assertions of the metabolites present within specific environments and how the production and depletion of metabolites is linked to specific microbes. This information could be broadly useful, from comparing metabolites across environments, to predicting competition and exchange of metabolites between microbes, and to designing stable microbial consortia. Here, we introduce Web of Microbes (WoM; freely available at: http://webofmicrobes.org), the first exometabolomics data repository and visualization tool.

Here we present the DOE Systems Biology Knowledgebase (KBase, http://kbase.us), an open-source software and data platform that enables data sharing, integration, and analysis of microbes, plants, and their communities. KBase maintains an internal reference database that consolidates information from widely used external data repositories. This includes over 90,000 microbial genomes from RefSeq4, over 50 plant genomes from Phytozome5, over 300 Biolog media formulations6, and >30,000 reactions and compounds from KEGG7, BIGG8, and MetaCyc9. These public data are available for integration with user data where appropriate (e.g., genome comparison or building species trees). KBase links these diverse data types with a range of analytical functions within a web-based user interface. This extensive community resource facilitates large-scale analyses on scalable computing infrastructure and has the potential to accelerate scientific discovery, improve reproducibility, and foster open collaboration.

Detection, characterization, and mitigation of faults on supercomputers is complicated by the large variety of interacting subsystems. Failures often manifest as vague observations like ``my job failed" and may result from system hardware/firmware/software, filesystems, networks, resource manager state, and more. Data such as system logs, environmental metrics, job history, cluster state snapshots, published outage notices and user reports is routinely collected. These data are typically stored in different locations and formats for specific use by targeted consumers. Combining data sources for analysis generally requires a consumer-dependent custom approach. We present a vocabulary for describing data, including format and access details, an annotation schema for attaching observations to a dataset, and tools to aid in discovery and publishing system-related insights. We present case studies in which our analysis tools utilize information from disparate data sources to investigate failures and performance issues from user and administrator perspectives.

Effective HPC system operations and utilization require unprecedented insight into system state, applications’ demands for resources, contention for shared resources, and system demands on center power and cooling. Monitoring can provide such insights when the necessary fundamental capabilities for data availability and usability are provided. In this paper, multiple Cray sites seek to motivate monitoring as a core capability in HPC design, through the presentation of success stories illustrating enhanced understanding and improved performance and/or operations as a result of monitoring and analysis.We present the utility, limitations, and gaps of the data necessary to enable the required insights. The capabilities developed to enable the case successes drive our identification and prioritization of monitoring system requirements. Ultimately, we seek to engage all HPC stakeholders to drive community and vendor progress on these priorities.
