1. 6. Exploring Selective coherence as a Solution to Self-invalidation in ArgoDSM

   University essay from Uppsala universitet/Datorteknik

   Author : Christopher Edberg; [2022]
   Keywords : ArgoDSM; Coherence; Performance; Selective Coherence; Distributed Shared Memory; Software-based Distributed Shared Memory; DSM; Software DSM; Computer Architecture; Parallel Computing;

   Abstract : Maintaining coherency in a distributed system can prove challenging, this is especially true for distributed shared memory systems. The problem with remote synchronization in the distributed shared memory software ArgoDSM occurs when a lock operation has to cross the boundaries of a node, this causes a large number of self-invalidations (SI) or self-downgrades (SD) which is costly.

3. 7. Parameterized Verification under The Total Store Order Memory Modelis EXPTIME-Complete

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Yacoub Hendi; [2021]
   Keywords : ;

   Abstract : In this paper, we study the problem of parameterized verification of a concurrent program running under the Total Store Order (TSO) memory  model. A concurrent program is a finite set of processes that are instances of the same pushdown system and which communicate through a set of shared variables. READ MORE

4. 8. Predictable Multiprocessor Platform for Safety- Critical Real- Time Systems

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Páll Axel Sigurðsson; [2021]
   Keywords : Composability; FPGA; Multicore processing; Predictability; Real- time systems; System on chip; FPGA; Förutsägbarhet; Komposibilitet; Mångkärnig bearbetning; Realtidssystem; System på chip;

   Abstract : Multicore systems excel at providing concurrent execution of applications, giving true parallelism where all cores can execute sequences of machine instructions at the same time. However, multicore systems come with their own sets of problems, most notably when cores in a system (or core tiles) share hardware components such as memory modules or Input/Output (IO) peripherals.

5. 9. Design and Implementation of a Distributed FleetSimulator

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Alen Gazibegovic; Fahad Rejabo; [2021]
   Keywords : ;

   Abstract : Det finns en efterfrågan för flottor av autonoma fordon i många industrier såsom gruvdrift, byggplatseroch lager där arbete ska utföras av robotar. Tre viktiga problem som man måste taitu med för att på ett säkert sätt använda autonoma fordon är: koordination för att etablerasäker trafik i miljön där robotarna agerar, rörelseplanering för att bestämma en genomförbarväg för robotarna, och kontroll av robotar för att utföra rörelsen längs den planerade vägen.

6. 10. A Study of Page-Based Memory Allocation Policies for the Argo Distributed Shared Memory System

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Ioannis Anevlavis; [2021]
   Keywords : ;

   Abstract : Software distributed shared memory (DSM) systems have been one of the main areas of research in the high-performance computing community. One of the many implementations of such systems is Argo, a page-based, user-space DSM, built on top of MPI. READ MORE
