Trail: Scalable and Low-Cost Temporal TLB Prefetching via Page-Table-Embedded Deltas
Konstantinos Kanellopoulos, Konstantinos Sgouras, Harsh Songara +2
Address translation is a major bottleneck in data-intensive workloads. TLB prefetching can hide translation latency, but existing spatial prefetchers struggle with irregular access…
Argus: Agentic, Reference-Calibrated, Tree-Guided, System-Software-Level Bottleneck Localization
Vlad-Petru Nitu, Harsh Songara, Konstantinos Sgouras +3
Operating system (OS) code can account for a substantial share of CPU execution time. First, as application logic is offloaded to heterogeneous accelerators (e.g., GPUs), the CPU i…
Valinor: Architectural Support for Fast, Energy-Efficient and Programmable Physical Memory Allocation
Konstantinos Kanellopoulos, Spiros Galanopoulos, Konstantinos Sgouras +7
Physical memory allocation establishes virtual-to-physical mappings on demand. In current systems, each minor page fault traps into the kernel and triggers pipeline flushes, stalls…
Revelator: Rapid Data Fetching via System-Software-Guided Hash-based Speculative Address Translation
Konstantinos Kanellopoulos, Konstantinos Sgouras, Harsh Songara +7
Address translation is a major performance bottleneck in modern computing systems. Predicting the physical address (PA) of requested data before address translation completes can h…
Roadmap to Neuromorphic Computing with Emerging Technologies
Adnan Mehonic, Daniele Ielmini, Kaushik Roy +50
The roadmap is organized into several thematic sections, outlining current computing challenges, discussing the neuromorphic computing approach, analyzing mature and currently util…
Virtuoso: Enabling Fast and Accurate Virtual Memory Research via an Imitation-based Operating System Simulation Methodology
Konstantinos Kanellopoulos, Konstantinos Sgouras, F. Nisa Bostanci +7
The unprecedented growth in data demand from emerging applications has turned virtual memory (VM) into a major performance bottleneck. Researchers explore new hardware/OS co-design…
