This presentation will tell the story of several compound semiconductor materials systems that have been developed for LEDs, the most important of which is the (Al,Ga,In)N system. In addition, you will learn more about this unusual material system's demonstration of blue-emitting LEDs for the first time and how it has penetrated about 50% of the conventional (i.e., incandescent, fluorescent, discharge) lighting market with enormous savings energy consumption.

First I will talk about our recent work on incorporating Non-volatile Memory (NVM) as Last Level Cache (LLC). I will highlight different tradeoffs (e.g. NVM latency vs capacity vs reliability) involved in designing such NVM based LLC and further discuss our solutions. In the end, I will go over some of the focus areas of our research Lab (Parallel Computing Lab) as well as some recent research directions.

Elections must satisfy a variety of seemingly contradictory properties. Join this talk to hear more about the simplistic nature of voting systems that must also be resistant to attacks from the most talented nation-state adversaries. You will also learn about our efforts to understand vulnerabilities in existing voting systems and to build sophisticated alternatives with state of the art technologies.

As HPC applications move from single GPU to multi-GPU, there are growing challenges around how to accurately model and predict the performance of future GPU designs and systems. This talk will provide a retrospective on the development of a simulation workflow used within NVIDIA today and the fidelity versus simulation-time trade-offs needed to enable system level simulation of HPC and data center workloads.
