The NEBULA RPC-Optimized Architecture

Babak Falsafi, Alexandros Daglis, Mark Johnathon Sutherland, Dionysios Pnevmatikatos, Siddharth Gupta

Large-scale online services are commonly structured as a network of software tiers, which communicate over the datacenter network using RPCs. Ongoing trends towards software decomposition have led to the prevalence of tiers receiving and generating RPCs wi ...

Data stream statistics over sliding windows: How to summarize 150 Million updates per second on a single node

Odysseas Papapetrou, Dionysios Pnevmatikatos, Grigorios Chrysos

Traditional data management systems map information using centralized and static data structures. Modern applications need to process in real time datasets much larger than system memory. To achieve this, they use dynamic entities that are updated with str ...

Design Guidelines for High-Performance SCM Hierarchies

Babak Falsafi, Javier Picorel Obando, Alexandros Daglis, Edouard Bugnion, Dmitrii Ustiugov, Mark Johnathon Sutherland, Dionysios Pnevmatikatos

With emerging storage-class memory (SCM) nearing commercialization, there is evidence that it will deliver the much-anticipated high density and access latencies within only a fewfactors of DRAM. Nevertheless, the latency-sensitive nature of memory-residen ...

The Mondrian Data Engine

Babak Falsafi, Javier Picorel Obando, Boris Robert Grot, Alexandros Daglis, Nooshin Sadat Mirzadeh, Dmitrii Ustiugov, Mario Paulo Drumond Lages De Oliveira, Dionysios Pnevmatikatos

The increasing demand for extracting value out of ever-growing data poses an ongoing challenge to system designers, a task only made trickier by the end of Dennard scaling. As the performance density of traditional CPU-centric architectures stagnates, adva ...

DeSyRe: On-demand system reliability

Sebastian Isaza, Babak Falsafi, Dionysios Pnevmatikatos

The DeSyRe project builds on-demand adaptive and reliable Systems-on-Chips (SoCs). As fabrication technology scales down, chips are becoming less reliable, thereby incurring increased power and performance costs for fault tolerance. To make matters worse, ...

ReSim, a Trace-Driven, Reconfigurable ILP Processor Simulator

Sotiria Fytraki, Dionysios Pnevmatikatos

Modern processors are becoming more complex and as features and application size increase, their evaluation is becoming more time-consuming. To date, design space exploration relies on extensive use of software simulation that when highly accurate is slow. ...
