Reliable Microsecond-Scale Distributed Computing
The landscape of computing is changing, thanks to the advent of modern networking equipment that allows machines to exchange information in as little as one microsecond. Such advancement has enabled microsecond-scale distributed computing, where entire dis ...
EPFL2023Recommendation on Live-Streaming Platforms: Dynamic Availability and Repeat Consumption
Live-streaming platforms broadcast user-generated video in real-time. Recommendation on these platforms shares similarities with traditional settings, such as a large volume of heterogeneous content and highly skewed interaction distributions. However, sev ...
ASSOC COMPUTING MACHINERY2021Efficient Protocols for Enforcing Causal Consistency in Geo-Replicated Key-Value Data Stores
Modern large-scale data platforms manage colossal amount of data, generated by the ever-increasing number of concurrent users. Geo-replicated and sharded key-value data stores play a central role when building such platforms. As the strongest consistency m ...
EPFL2020Fast General Distributed Transactions with Opacity
Aleksandar Dragojevic, Stanko Novakovic, Georgios Chatzopoulos
Transactions can simplify distributed applications by hiding data distribution, concurrency, and failures from the application developer. Ideally the developer would see the abstraction of a single large machine that runs transactions sequentially and neve ...
ASSOC COMPUTING MACHINERY2019A Minimally Intrusive Low-Memory Approach to Resilience for Existing Transient Solvers
We propose a novel, minimally intrusive approach to adding fault tolerance to existing complex scientific simulation codes, used for addressing a broad range of time-dependent problems on the next generation of supercomputers. Exascale systems have the pot ...
2019Increasing Availability in Distributed Storage Systems via Clustering
Michael Christoph Gastpar, Saeid Sahraei
We introduce the Fixed Cluster Repair System (FCRS) as a novel architecture for Distributed Storage Systems (DSS) that achieves a small repair bandwidth while guaranteeing a high availability. Specifically, we partition the set of servers in a DSS into s c ...
2018Experimental Validation of the Suitability of Virtualization-Based Replication for Fault Tolerance in Real-Time Control of Electric Grids
Jean-Yves Le Boudec, Wajeb Saab, Jalal Mostafa, Seyed Alireza Sanaee Kohroudi
Real-time control systems (RTCSs) perform complex control and require low response times. They typically use third-party software libraries and are deployed on generic hardware, which suffer from delay faults that can cause serious damage. To improve avail ...
2018Reliability Mechanisms for Controllers in Real-Time Cyber-Physical Systems
Cyber-physical systems (CPSs) are real-world processes that are controlled by computer algorithms. We consider CPSs where a centralized, software-based controller maintains the process in a desired state by exchanging measurements and setpoints with proces ...
