What's New?

Jetstream2 Introduces LLM Inference Service

The ACCESS resource Jetstream2 at Indiana University recently unveiled a Large Language Model (LLM) inference service tailored to the system’s users. The service provides access to advanced open-weight LLMs through two primary interfaces: a browser-based chat interface via Open WebUI similar to ChatGPT; and OpenAI-compatible inference APIs for seamless integration into projects and applications. For more information see Indiana University’s recent news release.

Are You Remembering to Cite ACCESS in Your Research Papers?

To ensure continued support for the NSF-funded cyberinfrastructure ecosystem, researchers are required to properly acknowledge the contribution of the ecosystem in their papers, presentations and other published works. Papers, presentations and other publications featuring work enabled by ACCESS should properly acknowledge the program’s contributions by citing this publication:

Timothy J. Boerner, Stephen Deems, Thomas R. Furlani, Shelley L. Knuth, and John Towns. 2023. ACCESS: Advancing Innovation: NSF’s Advanced Cyberinfrastructure Coordination Ecosystem: Services & Support. “In Practice and Experience in Advanced Research Computing (PEARC ’23),” July 23–27, 2023, Portland, OR, USA. ACM, New York, NY, USA, 4 pages. https://doi.org/10.1145/3569951.3597559.

In addition, please include the name of the resource and the following acknowledgment: This work used [resource-name] at [resource provider] through allocation [allocation number] from the Advanced Cyberinfrastructure Coordination Ecosystem: Services & Support (ACCESS) program, which is supported by National Science Foundation grants #2138259, #2138286, #2138307, #2137603, and #2138296."

SC25 Content Deadlines
