Trustworthy AI

Oct 30, 2023

Research Topics

Trustworthy AI research focuses on creating transparent, accountable, and reliable artificial intelligence systems. It includes two critical aspects: (1) eXplainable AI (XAI), which aims to make AI decisions understandable and free from bias. (2) Robust Machine Learning, which ensures AI systems can handle unforeseen conditions and adversarial attacks. The VIP team will apply the two aspects of Trustworthy AI to various scientific applications.

Algorithms: Programming Contest and Research

Mar 24, 2023

Goals of this Team

ALGORITHMS are an essential component of modern computing and have become increasingly important as the amount of data generated by businesses, governments, and individuals has grown exponentially. This VIP team centers on the study of algorithms, consisting of two threads:

  • Programming Contest Thread. Participating in programming contests can have several benefits: improving problem solving skills, enhancing programing skills, providing network opportunities, and enhancing career prospects. This thread serves as a channel for students who are interested in participating programming contest. With the support from the Computer and Information Science Department at UD, team members in this thread will collectively learn programming fundamentals, design contest strategies, participate in mock programming contests,  and finally, patriciate in programming contests in the US.
  • Research Thread. Algorithm research involves the study of algorithms, their properties, and their applications. The team in this thread will explore research topics in combinatorial optimization and social network analysis, in collaboration with the Computational Data Science Lab at UD (https://udel.edu/~amotong/).

Research Issues

Learning and using directives for parallel platforms; Migrating legacy code to GPUs and co-processors using high-level parallel programming models; Parallelizing irregular algorithms on massively parallel processors; Exploring Repeatability and Reproducibility issues.

Key Elements

High Performance Computing, Parallel Computing, Parallel Programming Models, Hardware Architectures, Portability, Scalability, Performance, Repeatability and Reproducibility.

Goals

Compute nodes pose thousand-way parallelism between parts of application, such as task parallelism, process-level and thread-level parallelism within a process and a core, along with hardware multithreading, instruction-level parallelism and pipelining of instructions. We see that technological advances have been instrumental in all scientific domains, be it astrophysics, medicine, finance and so on. However a major concern is if legacy code can tap into the massive potential of hardware resources; there is a real challenge to extract these parallelism. Moreover these codes are highly science-driven with varying workloads that demand dynamic load balancing and locality-aware scheduling. Modernizing legacy applications consisting of hundreds and thousands of lines of code for current and emerging architectures is a real challenge. This project aims to explore and create prototypes for parallelizing algorithms on heterogeneous platforms consisting of CPUs along with GPUs and Co-processors. Other hardware platforms of interest would be reconfigurable hardware such as FPGAs and specialized accelerators such as DSPs. However one of the primary challenges with the advances has been to understand how scientific applications were ported to hardware platforms using low-level or proprietary language – these are tied too close to the hardware. This project will explore ways to migrate such programs to a higher-level directive based programming model with a goal that in the process, a portable code be maintained. The overachieving goal is to write once and reuse multiple times such that less time is spent on programming and more time is spent on the science itself. This project will expose the students to large supercomputers comprising over 1 Million cores along with latest generation Co-Processors and several hundreds and thousands of GPUs.
