News and Announcements

Dr. Jack Dongarra to retire next summer

Director and Founder of ICL Dr. Jack Dongarra will retire on July 31, 2022. Since its inception in 1989, Jack has served as the head and heart of ICL, where he has cultivated a culture of discovery and excellence, leading over 425 researchers, staff, and students over a course of over 30 years. Part of the glue that holds the lab together, he stands as a Knoxville-based beacon for the international field of HPC. 

Jack assured the team that he will still be active and engaged until July 31, 2022 and then the plan is to become an Emeritus Professor. As an emeritus professor he will still have an office, be able to direct students, and apply for grants. 

2021 Retreat Returns as Hybrid In-Person/Virtual

The annual retreat marks a time for everyone at ICL to come together, celebrate each others accomplishments and get excited for future work. This year’s retreat was especially noteworthy; not only was it the return to meeting in-person, but Jack’s retirement  announcement at the end made it especially poignant. Meeting at the Park Vista in Gatlinburg, everyone at ICL got the opportunity to hear from one another, and for several people who joined the team during the COVID-19 pandemic, the retreat marked the first time meeting in-person.

Here are some reflections from the retreat:

“This being my first retreat, it is so interesting to finally understand what my ICL neighbors do! My experience at the retreat will foster some interesting collaborations in the future.”  – Wissam Sid Lakhdar

“Being new here, it was hard to keep track of who does what because ICL/GCL does so much! And the view was definitely one of the better views I’ve seen in my life. I look forward to what else I’ll learn while I’m here.” – Danny Mishler

An international birthday party

Due to COVID-19, Jack’s 70th birthday celebration was a highly anticipated event. Postponed from last summer, the Numerical Linear Algebra Group hosted “New Directions in Numerical Linear Algebra and High Performance Computing: Celebrating the 70th Birthday of Jack Dongarra,” a workshop sponsored by The Royal Society and The MathWorks.

This international workshop, July 7-8, focused on numerical linear algebra and high performance computing and brought together researchers from the UC-Davis and Berkley, North Carolina State, King Abdullah University of Science and Technology and of course Manchester and Tennessee.

Session topics included the Top500, Computing in the Old Days and, of course, Jack. Check them out here.

Conference Reports

ISC 2021 Digital: an HPC blockbuster featuring ICL researchers

Jack Dongarra, Piotr Luszczek and Hartwig Anzt presented at ISC 2021 Digital, which took place between June 24 and July 2. The international conference was widely attended, bringing together over 2000 attendees and 80 presenters.  The program of this years conference highlighted current developments in exascale computing, machine learning/AI, and cloud-based HPC, while also featuring discussions on emerging technologies such as quantum computing, neuromorphic computing, and next-generation HPC components.

On the second day of the conference, the three delivered a Modern Mixed- and Multi-Precision Methods Tutorial, later in the week presented an HPCG Benchmark Update.

Dr. Deborah Penchoff and Dr. Piotr Lusczek highlight interdisciplinary work at ACS Conference

Associate Director Dr. Deborah Penchoff delivered a talk and chaired two sessions at the American Chemical Society Resilience through Science conference, which took place at the Georgia World Conference Center from August 22-26. Deborah serves on the executive committee for the nuclear division of the ACS, where she’s positioned to support the nuclear community and the larger body of ACS for radio- and nuclear-chemistry needs.

At the conference, this role brought her to helping attendees understand the roles of high-performance computing and data science applications in the field of nuclear chemistry. In addition to chairing two sessions–Data Science and Artificial Intelligence Applications in Nuclear and Radiochemistry and Computational Science for Lanthanides and Actinides–she also gave a talk titled “High Performance Computing: Advances and Challenges in Modeling Rare Earth Elements and Actinides”.

Dr. Piotr Luszczek also gave a talk at the conference titled, “Numerical methods and benchmarking across scales, precisions, and hardware platforms”. For more information or to view the talks, visit the ACS website.

Interview

Paul Bagwell Then

Paul Bagwell

Where are you from, originally?
I was born in Kingfisher, Oklahoma, which is most notably recognized as the birthplace of Sam Walton.

Can you summarize your educational background?
I graduated from Pensacola Junior College in Pensacola, Florida with an Associates of Engineering degree.  I graduated from the University of Texas at Arlington with a Bachelor’s of Science in Electrical Engineering.

Where did you work before joining ICL?
I worked for ProNova Solutions in Maryville, TN as a software engineer for the Imaging and Positioning team.

How did you first hear about the lab, and what made you want to work here?
I heard about ICL from the internet.  I have found in medical imaging and also in surveillance systems that high performance GPU computing is necessary to meet requirements.  I wanted to learn more about how ICL develops HPC libraries and applications.

What is your focus here at ICL? What are you working on?
I am working on the SLATE test software.

What are your interests/hobbies outside of work?
I love the outdoors and like to camp and hike in the Great Smoky Mountains National Park.  I like to do yard work and gardening.

Tell us something about yourself that might surprise people.
I’m a grandfather of 6 grandchildren and one more on the way.

If you weren’t working at ICL, where would you like to be working and why?
Once I get proficient in HPC development, I would like to apply my new skills in the Medical Devices industry.
