Impact

To illustrate the magnitude of the ACCESS program’s impact, in a given month, more than 2.5 million jobs are run on average by more than 4,000 researchers representing more than 2,000 unique research projects.

What the research community is saying

The ACCESS program opens up a wide variety of computational resources for no direct cost to researchers.

– Nicolae Moise, Ohio State University

Uncovering fundamental functional mechanisms in the biological systems we study, such as MFSD2A transporter, presents a substantial challenge due to the sheer size and complexity of these systems. With the help of the powerful computational resources provided by ACCESS we are able to overcome this challenge.

For many years, the ACCESS, and its predecessor (XSEDE), program has been enabling our lab to perform computational discovery at the interface of biology and nanotechnology. Being able to use these state-of-the-art resources is pivotal to ensuring global leadership of U.S. science and the emergence of breakthrough technological innovations.

Having access to an open science system for this research has made it easy for our team to get results. Obtaining an allocation on ACCESS and then transitioning to a new machine, such as DeltaAI, was straightforward.

– Spencer Bryngelson, Georgia Tech

Thanks to NSF ACCESS allocations, we’re equipping both undergraduate and graduate students with the practical knowledge of how to harness high-performance computing for generative AI and LLM research—skills that will be essential for the next generation of AI researchers and practitioners.

– Thai Le, Indiana University

ACCESS allocations on Expanse at San Diego Supercomputer Center allowed us to complete our project in a resourceful manner—both time-wise and financially—without access to Expanse, we would not have been able to work so efficiently.

– Fernando De Sales, San Diego State University

If we didn’t have outside organizations helping with some of the resources, the cost of compute capacity, the accessibility of the capacity, would just be out of reach, and we’d be extremely limited in what we’d be able to do.

– Gary Bloom, search and rescue volunteer

We teach the basics of how agriculture data can be analyzed with computational techniques on supercomputers like those allocated by the ACCESS program. The students were enthralled with these hands-on computational activities via ACCESS.
