20. Industry Outreach in partnership with Institute for Computational Science (ICS) and Industrial Research Office (IRO) "... to out-compete, we must out-compute.... " Putting Pennsylvania based companies at a competitive advantage by helping meet their large-scale computing needs. Many small-to-medium sized companies, and even larger ones, do not have enough in-house expertise and resources for large-scale computations and as a result have not been able to use simulation and analysis tools with far greater frequency to help them innovate faster and become more competitive. Helping develop stronger relationship between faculty and industry by providing computational services; may lead to more alignment between faculty research areas and industry needs and positive impact on economic development along the I-99 corridor and throughout the commonwealth.
