  1. 1. Compressing Pointers for the Z Garbage Collector : Runtime compression of pointers in a concurrent setting

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Datalogi

    Författare :Linus Shoravi; [2023]
    Nyckelord :garbage collector; concurrent garbage collector; ZGC; pointer compression; hotspot;

    Sammanfattning : Pointers in 64-bit architectures are unlikely to exhaust their vast address range, and are as such needlessly big. Reducing the amount of memory a pointer occupies leads to reduced memory demands, better usage of memory, and better locality. LÄS MER

  3. 2. Improving relocation performance in ZGC by identifying the size of small objects

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jinyu Yu; [2022]
    Nyckelord :Garbage Collector; Java; Data locality; Garbage Collector; Java; Datalokalitet;

    Sammanfattning : Modern Garbage Collectors provide performance improvements by increasing program locality to utilize the faster CPU cache. A common approach is to move objects together according to the mutators’ access order, which brings more relocations during GC. LÄS MER

  4. 3. Mitigating garbage collection in Java microservices : How garbage collection affects Java microservices andhow it can be handled

    Uppsats för yrkesexamina på avancerad nivå, Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Författare :Amanda Ericson; [2021]
    Nyckelord :Garbage collector; Microservice; Docker; docker-compose; CMS; G1GC; Shenandoah GC; ZGC;

    Sammanfattning : Java is one of the more recent programming languages that in runtime free applications from manual memory management by using automatic Garbage collector (GC) threads. Although, at the cost of stop-the-world pauses that pauses the whole application. LÄS MER

  5. 4. An Experimental Study on the Behavioural Tendencies of Objects Classified As Hot and Cold by a Java Virtual Machine Garbage Collector

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hanna Nyblom; [2020]
    Nyckelord :;

    Sammanfattning : A constitutive hypothesis of the Java Virtual Machine garbage collector ”ThinGC”, presented by Mingkun Yang et al. [1], an extension of Oracle’s ”ZGC”, is that capitalising on possible temporal locality could optimise collection by limiting the total number of objects to manage. LÄS MER

  7. 5. Performance evaluation of Java garbage collectors for large heap transaction based applications

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Nicole Jagelid; [2020]
    Nyckelord :;

    Sammanfattning : The automated memory management mechanism known as garbage collection is a vital part of the Java Virtual Machine (JVM) and has considerable influence on the overall performance of a running application. Java Development Kit 13 (JDK13) offers several garbage collectors for the developer to choose from when configuring the environment. LÄS MER
