Includes an acrylic polymer to prevent scale formation in pipes and cooling towers.
In 2022, a small team of hardware engineers at gathered around a whiteboard in a cramped garage‑style lab on the campus of the University of Rochester. Their challenge? Build a PCI‑Express (PCIe) accelerator that could handle the ever‑growing data‑throughput demands of AI inference, high‑frequency trading, and real‑time video analytics— without inflating the bill of materials or draining power budgets.
