Case Study with Argonne National Laboratory


About Argonne National Laboratory

Kirill Prozument is an Assistant Chemist at the Chemical Sciences and Engineering Division of Argonne National Laboratory. His primary area of scientific interests is fundamental chemical reaction dynamics.

In his laboratory, they use the broadband chirped-pulse rotational spectroscopy to investigate chemical reactivity in the gas phase. With the advent of broadband rotational spectroscopy, automation of data analysis and, in particular, the assignment of rotational spectra became a necessity. Kirill and his team decided to approach the problem using artificial neural networks.

Daniel Zaleski, who is now Assistant Professor at Colgate University, was the lead researcher working with Kirill on this project. Daniel did most of his work while being a postdoctoral researcher at Argonne.

Tools of the Trade

While a standard PC was sufficient while using the feed forward artificial neural network, which operates with frequencies of rotational transitions, training a convolutional neural network on images of spectra required a customized PC. The need for Kirill's team to fully customize their workstation for neural network work is one reason he enlisted the help of Puget Systems.

Kirill outfitted his workstation with NVIDIA GeForce GTX 1080 Ti GPU. This powerful GPU is used to train the convolutional neural network which is part of a Rotational Assignment and Identification Network (RAINet).

Why Argonne Chose Puget Systems

The research Kirill and his team were performing required more horsepower than a standard, off-the-shelf PC could offer. Not only was the GPU important to his work, but he also needed lots of RAM and a high-performance SSD.

Kirill worked with Puget Systems consultants to come up with a workstation that is optimized to take advantage of the neural networks his research requires.

The work is published in the Journal of Chemical Physics, 149, 104106 (2018).
