Enabling system wide shared memory for performance improvement in PyCOMPSs applications
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessPython has been gaining some traction for years in the world of scientific applications. However, the high-level abstraction it provides may not allow the developer to use the machines to their peak performance. To address ... -
Characterizing the impact of last-level cache replacement policies on big-data workloads
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessThe vast disparity between Last Level Cache (LLC) and memory latencies has motivated the need for efficient cache management policies. The computer architecture literature abounds with work on LLC replacement policy. ... -
Internet routing paths stability model and relation to forwarding paths
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
Conference report
Open AccessAnalysis of real datasets to characterize the local stability properties of the Internet routing paths suggests that extending the route selection criteria to account for such property would not increase the routing path ... -
Nonparametric statistical methods to analyze the internet connectivity reliability
(Institute of Electrical and Electronics Engineers (IEEE), 2015)
Conference report
Open AccessFacing computational complexity when modeling network reliability by means of parametric models and corresponding statistical methods, in the present study, we apply nonparametric statistical methods, such as the Kaplan-Meier ... -
On the experimentation of the novel GCMR multicast routing in a large-scale testbed
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Conference lecture
Open AccessOriginally defined in the 90s, multicast is nowadays (re)gaining interest given the increasing popularity of multimedia streaming/content traffic and the explosion of cloud services. In fact, multicast yields bandwidth ... -
ILP modeling of many-to-many transmissions in computer networks
(Polish Academy of Sciences, 2012)
Conference report
Open AccessInformation flow in nowadays networks spreads in the exponential way. This fact is caused by the intensive changes in the Internet communication paradigms. Transmission in the Internet evolved from the simple one-to-one ... -
Cost-aware prediction of uncorrected DRAM errors in the field
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessThis paper presents and evaluates a method to predict DRAM uncorrected errors, a leading cause of hardware failures in large-scale HPC clusters. The method uses a random forest classifier, which was trained and evaluated ... -
Supporting beyond 5G applications by coordinating AI-based intent operation: an example for multilayer metro networks
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessIntent-based Networking (IBN) promises facilitating autonomous decision-making for service assurance. In this paper, we extend IBN by coordinating AI-based intents targeting at supporting beyond 5G services, like immersive ... -
Reinforcement learning-based autonomous multilayer network operation
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessWe propose an Intent-Based Networking solution based on Reinforcement Learning (RL). RL-based intents with specific operational objectives and coordinated operation between network layers are developed. Results show service ... -
Guaranteeing QoS requirements in long-haul RINA networks
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Conference report
Open AccessIn the last years, networking scenarios have been evolving, hand-in-hand with new and varied applications with heterogeneous Quality of Service (QoS) requirements. These requirements must be efficiently and effectively ... -
A hybrid packet/circuit optical transport architecture for DCN
(2019)
Conference report
Open AccessThe aim of this paper is to move away from today's multi-tier, manually operated, and performance limited Data Centre Network (DCN) towards more scalable, flexible, and optimized architecture of tomorrow. We propose a new ... -
Improving predication efficiency through compaction/restoration of SIMD instructions
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessVector processors offer a wide range of unexplored opportunities to improve performance and energy efficiency. However, despite its potential, vector code generation and execution have significant challenges, the most ...
