Computing and Data Challenges in Climate Change
ABSTRACT:
High Performance Computing has been a critical tool in understanding predicting climate change, and exascale computing combined with advances in mathematical modeling and parallel algorithm will lead to new insights in climate impacts, including the prevalence of hurricanes, droughts, wildfires and more. But the role for HPC in climate science goes well beyond physical modeling to the development of mitigation and adaptation strategies, and the use of high performance data analytics based with both traditional algorithms and machine learning. An explosion of new data sources from satellite imagery and embedded environmental sensors to portable genome sequencers and personal mobile phone data will transform our ability to monitor, infer and manage responses to a changing climate. What is the role of machine learning and HPC in climate change and how do the data-intensive problems change the requirements on hardware, programming support, parallel algorithms, and architecture? I will give an overview of several high performance modeling and analysis problems, their potential impacts on climate change and opportunities for mapping these to exascale architectures.

Role of HPC in next-generation AI
ABSTRACT
Scale has been central to the success of deep learning with the availability of large-scale data and compute infrastructure. However, for further progress, scale has to be coupled with novel algorithms. Next-generation AI will be unsupervised, robust and adaptive. It will incorporate more structure and domain knowledge. Examples include tensors, graphs, physical laws, and simulations. I will describe efficient frameworks that enable developers to easily prototype such models, e.g. Tensorly to incorporate tensorized architectures, NVIDIA Isaac to incorporate physically valid simulations and NVIDIA RAPIDS for end-to-end data analytics. I will then lay out some outstanding problems in this area.

Breaking the Scalability Wall
ABSTRACT
While HPC systems have considerably improved their raw compute performance and scalability over the last two decades – first with the adoption of compute clusters and then throughput computing – good communication performance and overall scalability are still very difficult to achieve with irregular and communication intensive sparse linear algebra and graph applications. Recent advances in chip packaging, such as Embedded Multi-die Interconnect Bridge (EMIB), novel Optical IO Photonics modules that can be directly integrated on chip, and aggressive system designs that eliminate the SW stack and natively support a Distributed Global Address Space, can be used to improve overall performance and potentially break the scalability wall of state of the arts computing systems.
