Todd Tannenbaum highlights the latest developments in the HTCondor Software Suite, previewing features coming in HTCondor v26 and showcasing improvements to monitoring, job management, metrics, data transfer, and resource provisioning. The talk covers new tools for analyzing distributed workloads, enhanced support for HPC and cloud environments, more efficient handling of shared input data, and upcoming capabilities designed to improve scalability and user experience across high throughput computing

Brian Bockelman explores how large language models and AI agents can make high throughput computing more accessible. The talk examines how AI-assisted tools, REST APIs, and the Model Context Protocol (MCP) can simplify HTCondor workflows while discussing the opportunities and limitations of using AI in scientific computing.

Justin Hiemstra presents new backend capabilities for the Pelican Origin, expanding support for a wider range of storage systems and improving how researchers access and share data. The talk covers backend architecture, protocol translation, caching, and ongoing work to make distributed data access more flexible and efficient.

Fabio Andrijauskas discusses how the Open Science Data Federation (OSDF) integrates with the National Research Platform to support distributed data access and computing. The talk highlights Pelican deployment, data transfer, monitoring, and infrastructure for managing data across geographically distributed research resources.

Brian Aydemir presents new features for sharing data in the Pelican Platform, including authentication, user management, and group-based access control. The talk explores how Pelican enables researchers to securely share and manage data while giving data owners greater control over permissions and collaboration.

Miron Livny opens HTC26 by introducing the conference theme, Transition, Trust, and Throughput (TT&T), and reflecting on major developments across the research computing community. The talk highlights leadership transitions within the OSG Consortium, the evolution of PATh into FabAID, the growing role of the multi-messenger astronomy community at HTC26, and the importance of trusted software and strong partnerships in advancing scientific computing.

Todd Tannenbaum discusses what's new in the HTCondor Software Suites (HTCSSS) and what's coming up. Topics include Release numbering Scheme, using container images, new authenticated docker support, Pelican local cache on the EP, sharing input common files, and more.

While there are perhaps hundreds of petabytes of datasets available to researchers, instead of swimming in seas of data there is often a feel of sitting in a data desert: there’s a mismatch between what sits in carefully curated repositories around the world versus what’s accessible at the computational resources locally available. The Pelican Project (https://pelicanplatform.org/) aims to bridge the gap between repositories and compute by providing a software platform to connect the two sides. Pelican’s flagship instance, the Open Science Data Federation (OSDF), serves billions of objects and more than a hundred petabytes a year to national-scale resources. This tutorial, targeted at end-user data consumers and data providers, will cover the data access model of Pelican, guide participants to access and share data through an existing data federation, and consider how data movement via Pelican and the OSDF can enable their research computing.

Brian Bockelman presents on the Pelican work debugging Pelican client failures and approaches to learn what happened.

NSF NCAR’s labs and programs collectively cover a breadth of research topics in Earth system science, from the effects of the Sun on Earth's atmosphere to the role of the ocean in weather and climate prediction, as well as supporting and training the next-generation of Earth system scientists. However, with the current legacy `download and analyze’ model followed by most of our remote users, we are not realizing the full research potential of NCAR’s wealth of datasets. Our goal is to integrate NCAR’s curated data collections with the OSDF data and compute fabric to broaden access capabilities. In this talk, we present progress on this collaboration and demonstrate geoscience workflows which ingest data from NCAR’s Research Data Archive using pelicanFS via OSDF caches.

Justin Hiemstra discusses access to data via tokens that you bring to the Origin to get your data. Hiemstra's talk explores the problems this complex system is trying to solve, why we don't use something simple like passwords and what Pelican is going to make it easier for users.

CHTC Fellows discuss the work and goals of their Fellows Projects - for CHTC and Pelican

Christina Koch presents on facilitation impacts at HTC25. Lead Research Computing Facilitator Christine Koch describes the facilitation services provided to researchers and ways to connect. In addition, Koch discusses PATh's role as a resource provider for NAIRR and building a data community.

Brian Bockelman, the Pelican Platform PI, discussed what Pelican does, and how it can be used. Bockelman discusses the Pelican Project that builds a software platform that delivers data to throughput computing and the Open Science Data Federation (OSDF), a global deployment of the platform.
