Abstract: Swarm Intelligence is the collective behavior of each member, so called agents or particles, in the swarm. These particles interact with one another and with their environment during their work. Each individual particle follows a set of simple rules and communicates with others on what is the result of it behavior during their interaction. In the meantime, the whole particles in the swarm behave to fine their objective, such as food source. Without any centralized control over how individual particle should behave, the iterations of local interaction among particles and the behavior of the swarm finally lead to the convergence of global behavior of the swarm. Example of Swarm Intelligence in insects such as ant colonies, bee colonies, bird flocking and fish schooling. The interaction locally among particles is so called “exploitation”. On the other hand, the global behavior of the swarm is called “exploration”. In an optimization problem, the balance of exploitation and exploration behavior is the key that leads the swarm to reach the optimal solution. This presentation will show how these two mechanisms of the Swarm Intelligence work.

Abstract: Currently, the system-level performance of computer is becoming a big obstacle for realizing the advanced human-centered society driven by upcoming Artificial Intelligence (AI) technologies. For instance, many deep learning programs, which become a typical component for AI-based applications, has struggled with lack of performance even if it is implemented on the state-of-the-art CPUs or GPUs. Therefore, techniques that realize high-performance and high-efficiency computer systems are expected to be an enabler of emerging new AI applications such as self-driving cars and autonomous intelligent robots. In the context of system performance matter, we highlight specialization for inherent memory access locality which will be a clue to its solution. We attempt to improve inefficient part of memory references by fully customizing memory access patterns of application programs towards the target hardware. Here, we propose memory-centric performance engineering that orchestrates various expertise and wisdom of cross-cutting fields of computer systems such as architecture, high-performance computing, programing, software and hardware design. To procreate memory-centric performance engineering, we investigate the followings: (1) memory-centric customization and co-design methodology, (2) scientific modeling of system performance and quality of the performance, (3) automation of customization and co-design driven by mathematical optimization and machine learning techniques. In this presentation, we present our experiences and on-going approaches for memory-centric performance engineering. Finally, we will show the importance of building open ecosystem for highly-customized computer systems for AI applications and resultant AI-inspired principles for computer and mathematical sciences.
