Brent has over 30 years of experience with high performance computers, specializing in performance optimization. He started optimizing codes with the Cray XMP and has progressed through the current nVidia GPUs and Intel Xeon based clusters. He helped to design the hardware for the Supertek S-2, which became the Cray EL90. He was the lead technical support engineer at nCUBE, the system administrator in charge of the Cray T3D at the EPA Supercomputer Center, the project team lead at the Maui High Performance Computer Center, and was on the Blue Gene performance team at IBM. Brent holds 11 patents, most of them having to do with the improvement of high performance networks in massively parallel computer systems.
