  1. 1. Improving Dependability of Space-Cloud Payload Processor by Storage System

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Hassan Said; Stephanie Liza Johansson; [2023]
    Nyckelord :Fault tolerant; Markov analysis; Onboard processing; SSD array architecture; SSD; EDAC; RAID; Hamming code; Reed Solomon; Dependability evaluation; File systems; ZFS; Ext4.;

    Sammanfattning : Due to the usage of complicated platforms and current high-performance space computing technology, onboard processing in small satellites is expanding. Space-cloud payload processors with Commercial Off-The-Shelf (COTS) components, that are required to be radiation-tolerant, are used to perform the onboard processing. LÄS MER

  3. 2. Spark for HPC: a comparison with MPI on compute-intensive applications using Monte Carlo method

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Shen Huije; Tingwei Huang; [2018]
    Nyckelord :;

    Sammanfattning : With the emergence of various big data platforms in recent years, Apache Spark - a distributed large-scale computing platform, is perceived as a potential substitute for Message Passing Interface (MPI) in High Performance Computing (HPC). Due to the limitations in fault-tolerance, dynamic resource handling and ease of use, MPI, as a dominant method to achieve parallel computing in HPC, is often associated with higher development time and costs in enterprises such as Scania IT.

  4. 3. Dynamic Process Relocation in Multiprocessor Systems : Mixed-Criticality Aware Implementation

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Tage Mohammadat; [2017]
    Nyckelord :;

    Sammanfattning : Enabling deterministic dynamic process relocation in electronic systems creates opportunities for dynamic computational load balancing, fault tolerance, power consumption management, which can be positively correlated with improvements in longevity, safety and energy-efficiency. Additionally, dynamic process relocation can be leveraged to enhance the adaptability of mixed-critical systems operating in open and changeable environments, which is a current market driver for safety-concerned industries like avionics, automotive and railways.

  5. 4. Implementation of a Distributed Fault-Tolerant NoC-based Architecture for the Single-Event Upset Detector

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Eleftherios Kyriakakis; [2017]
    Nyckelord :;

    Sammanfattning : Today, with the rise of the private sector in space exploration, space missions are becoming more frequent than before. This in relation to the fact that modern electronics scale both faster and denser, the effects of radiation become a critical design requirement for fault-tolerance in on-board space computer systems.

  7. 5. Dynamic Fault Tolerance and Task Scheduling in Distributed Systems

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Jonatan Broberg; Philip Ståhl; [2016]
    Nyckelord :reliability; distributed computing; dynamic fault tolerance; task scheduling; replication; Technology and Engineering;

    Sammanfattning : Ensuring a predefined level of reliability for applications running in distributed environments is a complex task. Having multiple identical copies of a task increases redundancy and thereby the reliability. LÄS MER
