Stability in Health vs. Abrupt Changes in Disease in the Human Gut Microbiome...Larry Smarr
The document summarizes research on analyzing changes in human gut microbiome composition over time using 16S rRNA gene sequencing and the UniFrac metric. It presents findings that:
1) A healthy person's gut microbiome composition generally remains stable over periods of 60 days based on samples from multiple body sites.
2) In contrast, for people with C. difficile infections, their gut microbiome composition can abruptly shift to a healthy state within days after a fecal microbiota transplant from a healthy donor.
3) Analysis of one individual's gut microbiome samples over 3.5 years found the composition abruptly shifted between two distinct stable states that correlated with changes in symptoms and weight, before and after a

CENIC is a non-profit organization that operates an 8,000+ mile fiber optic network connecting over 12,000 sites across California, including K-12 schools, universities, libraries, and research organizations. It has over 750 private sector partners and contributes over $100 million annually to the California economy. CENIC's network enables research and education collaborations, innovation, and economic growth statewide. It also operates a wireless research network called PRP that connects wireless sensors to supercomputers, supporting applications like wildfire modeling.
Global Research Platform Workshops - Maxine BrownLarry Smarr
The document announces a workshop on global research platforms that will be held virtually in 2021 and in Salt Lake City in 2022, with topics including large-scale science, next-generation platforms, data transport, and international testbeds. It also announces the 4th Global Research Platform Workshop to be held in October 2023 in Limassol, Cyprus co-located with the IEEE eScience 2023 conference.
EPOC and NetSage provide engagement and network monitoring services to support research and education. NetSage collects anonymized network flow data to help understand traffic patterns and troubleshoot performance issues. It provides dashboards and analysis to answer common questions from network engineers and end users. Examples of NetSage deployments and use cases were shown for the CENIC network, including top sources and destinations of traffic, debugging slow flows, and analyzing international traffic patterns by country over time.
The document discusses accelerating science discovery with AI inference-as-a-service. It describes showcases using this approach for high energy physics and gravitational wave experiments. It outlines the vision of the A3D3 institute to unite domain scientists, computer scientists, and engineers to achieve real-time AI and transform science. Examples are provided of using AI inference-as-a-service to accelerate workflows for CMS, ProtoDUNE, LIGO, and other experiments.
Democratizing Science through Cyberinfrastructure - Manish ParasharLarry Smarr
This document summarizes a presentation by Manish Parashar on democratizing science through cyberinfrastructure. The key points are:
1) Broad, fair, and equitable access to advanced cyberinfrastructure is essential for democratizing 21st century science, but there are significant barriers related to knowledge, technical issues, social factors, and balancing capabilities.
2) An advanced cyberinfrastructure ecosystem for all requires integrated portals, access to local and national resources through high-speed networks, diverse allocation modes, embedded expertise networks, and broad training.
3) Realizing this vision will require a scalable federated ecosystem with diverse capabilities and incentives for partnerships to meet growing needs for cyberinfrastructure and
Panel: Building the NRP Ecosystem with the Regional Networks on their Campuses;Larry Smarr
This document summarizes a panel discussion on building the National Research Platform ecosystem with regional networks. The panelists discussed how their regional networks are connecting to and using the Nautilus nodes of the NRP. Examples included using NRP for deep learning and computer vision research at the University of Missouri, challenges of adoption in Nevada and potential solutions, and Georgia Tech's new involvement through the Southern Crossroads regional network. The regional networks see opportunities to expand NRP access and training to enable more researchers in their regions to take advantage of the platform.
Open Force Field: Scavenging pre-emptible CPU hours* in the age of COVID - Je...Larry Smarr
The document discusses Open Force Field (OpenFF), an open-source project that enables rapid development of molecular force fields through automated infrastructure, open data and software, and an open science approach. OpenFF provides access to large quantum chemical datasets, runs quantum chemistry calculations on pre-emptible cloud resources with minimal human intervention, and facilitates easy iteration and testing of new force field hypotheses through an open development model.
Panel: Open Infrastructure for an Open Society: OSG, Commercial Clouds, and B...Larry Smarr
The document discusses open infrastructure for an open society and the role of commercial clouds. It describes how the National Research Platform (NRP), Open Science Grid (OSG), and Open Science Data Federation (OSDF) provide open infrastructure through open source components that anyone can contribute to and use. It then discusses how Southwestern Oklahoma State University leveraged NRP resources on their campus and engaged students and local teachers. Finally, it outlines the pros and cons of commercial clouds, when they may be suitable to use, and how tools like CloudBank and Kubernetes can help facilitate science users' access to cloud resources.

Frank Würthwein - NRP and the Path forwardLarry Smarr
NRP will replace PRP and aims to democratize access to national research cyberinfrastructure. The long term vision is to create an open national cyberinfrastructure by federating resources across research institutions. Key innovations include an innovative network fabric, application libraries for FPGAs, a "bring your own resource" model, and innovative scheduling and data infrastructure. The NSF has funded the Prototype National Research Platform project to support NRP for the next 5 years. NRP aims to grow resources, introduce new capabilities, and be driven by the research community.

2. Carl Woese Was My Mentor
for Microbial Genomics
To Carl Woese: “What I have always understood
is that you were responsible for ‘turning Larry Smarr on’
to biology, to evolution, to the adventures in living systems.”
– John Wooley, July 26, 2006
To Larry Smarr: “I want to talk to you about setting up
a megabase sequencing unit at the U of I
I take this as necessary to the survival of good biology on this campus,
for it is clear that megabase sequencing
will be a major biological activity in the future.
- Carl Woese, July 6, 1995

3. There are 100 billion stars in the
Andromeda galaxy…
…and 100 billion galaxies in the
known universe.
4. It’s a microbial world…
…there are 100 million times as many bacteria on Earth
as stars in the universe.
Microbiology is the ultimate Big Data science!

6. Carl’s Late Thoughts on
the Critical Need for Research in Microbial Ecologies
The second major direction involves the nature of the global ecosystem.
. . . Bacteria are the major organisms on this planet—
in numbers, in total mass, in importance to the global balances.
Thus, it is microbial ecology that . . . is most in need of development,
both in terms of facts needed to understand it,
and in terms of the framework in which to interpret them.”
-Carl Woese Current Biology 15: R111–R112 (2005).
I started intensively working on microbial ecologies in 2005
