Talk Titles and Abstracts

1st Speaker: Shigeki Tomishima

Title:

Memory in Supercomputers for FugakuNEXT and Beyond

Abstract:

Thanks to AI boom, the data transfer from memory to the computing units became more important and the memory device/ architecture with higher BW and larger but lower power are required.

The presenter will talk about the current direction on the memory devices and the upcoming architecture with introducing FugakuNEXT project.

2nd Speaker: Francesco Antici

Title:

Leveraging AI to Enhance HPC Workflows: From Code Generation to Resource Optimization

Abstract:

The integration of Artificial Intelligence (AI) and Large Language Models (LLMs) into High-Performance Computing (HPC) workflows is reshaping the way scientific applications are developed, optimized, and executed. Recent LLMs are capable of automatic code generation, systematic detection of security threats, and optimization of resource allocation through workload characterization. By integrating such tools in production HPC environments, it is possible to accelerate development cycles, improve performance efficiency, enforce security measures, and enable more adaptive and resource-aware computing workflows.

3rd Speaker: Anshuman Bhardwaj

Title:

Analog Gravity in Bose–Einstein Condensates and Strained Graphene

Abstract:

Analog gravity uses controllable condensed-matter systems to probe quantum-field phenomena in curved spacetime. I will discuss two representative platforms: a rapidly expanding toroidal Bose–Einstein condensate, which can emulate the primordial inflationary universe and exhibit spontaneous quasiparticle creation, and strained graphene where we realize the Unruh effect. In the graphene case, I will also discuss Takagi’s statistics inversion, in which the thermal spectrum of the created Dirac fermions depends on dimensionality, with possible signatures in spectroscopic and transport measurements. Together, these examples illustrate how table-top quantum simulators can provide experimentally accessible windows into phenomena traditionally associated with cosmology and relativistic quantum field theory.
