July 23 – 27, 2023

Portland Oregon

We’re looking forward to the PEARC 23 (Practice and Experience in Research Computing) conference in Portland, Oregon this year. PSC staff will be contributing by presenting papers, workshops, tutorials, and visualization demos, and sitting on panels. Here’s where you can find them:

Monday July 24

8:30 – 4:30 PDT


Providing novel accelerator systems to the science and engineering community

There are multiple novel accelerator hardware-based supercomputers and resources that are being built and made available to the science and engineering community…offerings from ARM, Habana Labs, Cerebras, Graphcore, SambaNova to name a few. These machines differ in that the software stack is generalized to support a large set of applications. In addition to offering tremendous performance gains by transparently taking advantage of specialized architecture, these generally applicable frameworks coupled with purpose-built tools to seamlessly transition applications and scientific workflows between generalized HPC environments and the specialized CI resources. Discussions will include the ideas behind such hardware, project plans that are developed jointly with vendors of these systems, the architecture of such machines including processor cores, interconnects, file systems etc. Also, how the system is managed, what cluster management tools and approaches are used, what system monitoring tools are used, how the I/O subsystems are architected and managed, what batch systems are used, and how user accounts and allocations are managed for researchers. Finally, a bit on management and operational aspects of these novel systems. And from a user and application support perspective, a bit on how these machines are benchmarked, how users are onboarded, how researchers are applying workflows that are utilizing the machines, challenges and experiences with onboarding, training and enabling researchers to use these machines effectively, and how the users have been able to port, run and optimize applications. Our experience is that there is close and ongoing collaboration needed among three parties – the centers’ system and applications staff, the experts from the vendors and the ARC user community.

How To ACCESS?: An Informational and Demonstrational Overview on How to Get Started, Leverage, and Get Involved With ACCESS Systems and Services

The Advanced Cyberinfrastructure Coordination Ecosystem: Services & Support (ACCESS) program promotes discovery and support of advanced CI resources, operational support and accessibility, and monitoring and measurement of some of the most innovative systems in the world. The foundational mission of ACCESS is to democratize the availability and accessibility to more diverse communities. To facilitate this, ACCESS provides a wide range of services including assistance with allocating resources on nationally available computing resources, support for using them with user-facing tools and expert knowledge, operational support in maintaining policies and procedures, along with monitoring and measurement. In this workshop a combination of demonstrations and informational sessions will be presented to highlight the basics of getting started, what resources and tools are available, and how to get involved with ACCESS.

A Guideline to Writing a Successful Proposal for ACCESS and Other National Compute Resources

Navigating the everchanging national landscape of the national computing resources is difficult for any researcher may they be beginners and seasoned long-time users. During our long involvement in the review and allocation process of resources of the XSEDE, ACCESS, leadership-class programs (Blue Waters, Frontera, etc.) we have helped many scientists to succeed. We ask to kindly accept our tutorial submission at the PEARC 2023 conference that will address systematically the two most persistent problems that researchers face during the application process. Selecting the appropriate resource among the variety of choices offered and writing a successful application that translates a solid science project into a strong proposal ready to take on the competition.

Visualizing the Future of Louisiana's Coastline

Matt Yoder will present “Visualizing the Future of Louisiana’s Coastline” as part of the Applications track for Scientific Tools.

Two other authors will also present research on this topic.

Be sure to stop in to the Posters & Viz reception in the ballroom at 5:45 to chat with Matt and Juan and to see the effects that a slate of proposed interventions are expected to have on Louisiana’s coastline 5, 10, even 50 years in the future.

5:45 – 7:45 PDT

Visualization demo

Visualization demo: Effects of Proposed Mitigation Projects on the Louisiana Coastline

As part of the Posters & Viz reception in the ballroom, Matt Yoder  and Juan Puerto will demonstrate their vizualization tool that predicts the effects of proposed interventions on the Louisiana coastline from 5 to 50 years in the future.
