A recent article by Dimitris Gizopoulos, published in Computer Architecture Today, explores the evolving role of microarchitectural modeling and simulation in today’s accelerator-rich, large-scale computing systems.
Microarchitecture simulators remain essential tools for designing modern computing chips, enabling early and systematic exploration of performance, power, and resilience trade-offs. Joint performance–resilience modeling has now become a core component of development activities worldwide, including within the DARE project.
DARE relies extensively on microarchitectural simulation to guide design decisions across the three computing engines it is developing: a high-performance GPP, VEC, and AIPU.
The article discusses key challenges and questions closely aligned with DARE’s technical work, including simulation throughput, the impact of accelerator-rich designs on simulator complexity, and the validation of performance and resilience at scale.
Recommended reading for anyone interested in next-generation HPC and AI system design.
