Exploring the Landscape of Midwest Research Computing and Data Consortium

Summer Wang Professional Headshot

This is a series where we dive into the world of the Midwest Research Computing and Data Consortium, exploring its members, their challenges, and future prospects. We had the opportunity to speak with Summer Wang from the High Performance Computing (HPC) Client Services Department at the Ohio Supercomputer Center (OSC), who shared her insights on the field. Edited excerpts from the conversation below:

About My Role

As a senior client engineer at the Ohio Supercomputer Center, my journey began when I pursued a Ph.D. in nuclear engineering at The Ohio State University. My advisor’s focus was on experimental work, so I turned to OSC’s supercomputing resources for my simulations. This experience led to my current role at OSC, where I support the Help Desk team, guide junior staff, and work closely with clients to maximize their use of our resources. My day involves monitoring tickets, providing technical guidance, and identifying gaps in our services that we can address.

Computational Fluid Dynamics (CFD) Expertise

With significant experience in computational fluid dynamics (CFD) and prior programming training, my background has turned out to be crucial. In fact, there was an opening at OSC for a CFD expert, and that’s how I was hired. I started by supporting the simulation and modeling for small and medium-sized manufacturers who didn’t have their own clusters, so we facilitated their usage of OSC’s resources. Although my role has evolved in the sense that I don’t require my CFD expertise on a day-to-day basis, the programming skills I learned and continue to learn on the job remain quite relevant. I develop tools for users and staff to enhance our efficiency and mentor undergraduate students needing technical support. While we now cater to over 6,000 users with a broad range of needs, my foundational skills help me address the broad range of needs and challenges our users face. 

Machine Learning and AI Integration

HPC is constantly evolving with new technologies. A decade ago, I didn’t know much about artificial intelligence or machine learning. I remember going to a conference where there was a discussion about TensorFlow, and I had to learn about it to support our users. With machine learning and artificial intelligence slowly becoming integral to HPC, we at OSC provide resources such as GPUs and libraries like TensorFlow and PyTorch to support a vast array of projects. I assist users, especially beginners, in establishing their workflows and provide basic training. The evolution of HPC means continuously learning new technologies, such as artificial intelligence (AI), to better support our users.

Research and Client Needs

My work involves significant research and alignment with client needs, including technology transfer and process improvements. For example, we recently received National Science Foundation (NSF) funding for an HPC Q&A service that uses AI to respond to user queries based on our documentation and resources. This project, led by Rutgers University, in collaboration with National Center for Supercomputing Applications (NCSA) and Texas Advanced Computing Center (TACC), aims to enhance user experience and reduce our workload.

Collaboration, Challenges and Future Trends

Collaboration is key to our success at OSC. A notable project is the Protected Data Service, developed in response to user needs. We are working with other institutions in Ohio to create the right environment for this project, demonstrating the benefits of multidisciplinary expertise and teamwork. However, a major challenge in HPC is data privacy and security, especially with the increasing openness of data. Establishing robust policies and governance around AI usage is also critical to prevent misuse. Over the next decade, these challenges will require continuous adaptation and vigilance.

Advice for Aspiring Individuals

For those looking to enter the field of HPC, staying informed about new technologies and being ready to learn is essential. Networking and building professional connections are also crucial. Especially for newcomers in the field, don’t ever hesitate to ask for advice. I’ve learned a lot from clients and colleagues over the years and you will find people always willing to pass it on. For example, recently I created a Slack channel at OSC to keep everyone updated on workshops, tutorials, and articles because learning from clients and colleagues has been invaluable throughout my career. 

Personal Interests

Outside of work, I enjoy running every day, which helps clear my mind and start the day fresh. I also enjoy dancing, even though I’m not very good at it (laughs). These hobbies keep me balanced and energized.
