Researchers in Civil Engineering are interested in exploring the computing infrastructure that would be critical to support a data-rich future for connected vehicle transportation systems. Clemson ACI-REFs assisted in the design and implementation of such an experimental infrastructure. We also facilitated and trained Civil Engineering students in using large-scale computing resources, on-site and national, to deploy this infrastructure for research activities.
Since 2016, a Civil Engineering research group led by Dr. Mashrur Chowdhury has explored the challenge of moving and integrating massive amounts of data coming from various sources (such as roadside and roadway equipment, social media, online weather resources, etc.,) to a large-scale computing infrastructure. This is a new research direction aimed at the upcoming deluge of data that results from a future society where everything is connected. To date, most Civil Engineering research in the area of connected transportation systems has focused primarily on the transportation applications themselves, such as… . Less research has addressed the backbone of cyberinfrastructure that is critical to these transportation applications.
One challenge for this area of research is to evaluate various cyberinfrastructure designs quickly and at relatively large scale for validation purposes. This is important because… A shared-memory solution is not appropriate, as the individual computing entities need to reside on isolated physical devices. Another challenge is to ensure the maintainability and reproducibility of these experiments for future work. Dr. Chowdhury’s group thought working with ACI-REFs would help them address these challenges…?
Clemson University’s ACI-REFs Linh Ngo and Ashwin Srinath worked with graduate students and post-doctoral researchers from Dr. Chowdhury’s research group to identify potential solutions to these challenges. The scope of assistance that Dr. Chowdhury’s students received include training and consultation services (including the Palmetto cluster?). For training, the researchers learned Python programming, Linux, and how to use Clemson’s research computing resources. For research consultation, the facilitators worked with the researchers to help them understand a range of topics, including the temporal and spatial requirements of connected vehicles transportation, and back-end computing infrastructure performance metrics. The facilitators also introduced the research group to CloudLab, a cloud-based public computing resource that enables the deployment of experimental computing infrastructures. This allowed them…
Using CloudLab and Clemson University’s Palmetto, Dr. Chowdhury’s research group was able to design and deploy a large-scale experimental environment including more than a hundred computing instances running on isolated hardware instances located on different host institutions.
This environment allows… Through this environment, a prototype data delivery infrastructure was tested and results published in a peer-review journal and presented at a professional conference.
