Lou Marchant, Board Member


Lou Marchant is originally from Wyoming and moved to Texas to go to school. She received a BS in Architecture as a Master Builder from UT Arlington and a MS in Civil Engineering from Southern Methodist University specializing in structures and materials.

To put herself through school, Lou bought and sold British sports cars, worked as a Steel Detailer and was a Resident Engineer at various airports for navigational installations. After college she became Frito Lay’s Corporate Architect and Structural Engineer using Finite Element Analysis and Computational Fluid Dynamics products from the Rand Group. This introduced her into the world of HPC using larger computer systems to innovate faster.

Lou then joined the Rand Group to work on special products and was also introduced to Cray Research and the world of supercomputers. At the time, Gene Amdahl was going after Cray Research with his own idea for a supercomputer and started Elxsi Computers. Lou joined Elxsi working on special projects for the soon to be released supercomputer. In the end, the computers were 50 years ahead of their time and the materials were not available to build the systems.  Lou ended up moving to Cray Research as part of the Business Systems Division. The BSD team designed a system to solve HPC business problems which were as computationally intense as engineering simulations.

Three years later, Cray Research was sold to Silicon Graphics and the Cray BSD group was then sold to Sun Microsystems. At Sun, Lou was Board Chair of the 50 Data Center Ambassadors and Product Boss for the E10k, E15K, E20k and the E25k driving the division to a multi-billion a year product line.

After 14 years Sun was sold to Oracle Corp. and Lou joined IBM as a Pureflex Computer Specialist focused on solving HPC problems for Aerospace and Defense companies. She was successful until IBM sold the Pureflex Systems to Lenovo. Lou then joined Cray Computers as an Account Executive. While at Cray Computers, Lou attended an Aerospace Conference, and the biggest request was to have the capability to run various workflows which normally takes a Cray or large cluster but do it in the cloud.  Later that year, Lou was introduced to Rescale, Inc and they had a control plane for running large engineering simulations in the cloud. Shortly after learning about Rescale, she joined the company and has been working with companies to do HPC in the cloud for over five years.

Outside of HPC,  Lou is a Driving Instructor at the racetrack, enjoys vintage racing, collecting classic British cars and motorcycles and traveling around the globe.
