    Recently proposed hybrid dataflow and shared memory programming models combine these two underlying models in order to support a wider range of problems naturally. The effectiveness of such hybrid models for parallel ...
  • Atomic dataflow model 

    Gajinov, Vladimir (Universitat Politècnica de Catalunya, 2014-11-20)
    Doctoral thesis
  • Atomic quake: using transactional memory in an interactive mulitplayer game Server 

    Zyulkyarov, Ferad; Gajinov, Vladimir; Unsal, Osman Sabri; Cristal Kestelman, Adrián; Ayguadé Parra, Eduard; Harris, Tim; Valero Cortés, Mateo (2009)
    Conference report
    Open Access
    Transactional Memory (TM) is being studied widely as a new technique for synchronizing concurrent accesses to shared memory data structures for use in multi-core systems. Much of the initial work on TM has been evaluated ...
  • DaSH: a benchmark suite for hybrid dataflow and shared memory programming models: with comparative evaluation of three hybrid dataflow models 

    Gajinov, Vladimir; Stipic, Srdjan; Eric, Igor; Unsal, Osman Sabri; Ayguadé Parra, Eduard; Cristal Kestelman, Adrián (Association for Computing Machinery (ACM), 2014)
    Conference report
    Restricted access - publisher's policy
    The current trend in development of parallel programming models is to combine different well established models into a single programming model in order to support efficient implementation of a wide range of real world ...
  • Dynamic transaction coalescing 

    Stipic, Srdjan; Karakostas, Vasileios; Smiljkovic, Vesna; Gajinov, Vladimir; Unsal, Osman Sabri; Cristal Kestelman, Adrián; Valero Cortés, Mateo (Association for Computing Machinery (ACM), 2014)
    Conference report
    Restricted access - publisher's policy
    Prior work in Software Transactional Memory has identified high overheads related to starting and committing transactions that may degrade the application performance. To amortize these overheads, transaction coalescing ...
  • Integrating dataflow abstractions into the shared memory model 

    Gajinov, Vladimir; Stipic, Srdjan; Unsal, Osman Sabri; Harris, Tim; Ayguadé Parra, Eduard; Cristal Kestelman, Adrián (2012)
    Conference report

    In this paper we present Atomic Dataflow model (ADF), a new task-based parallel programming model for C/C++ which integrates dataflow abstractions into the shared memory programming model. The ADF model provides pragma ...
  • Integrating dataflow abstractions into transactional memory 

    Gajinov, Vladimir; Milovanovic, Milos; Unsal, Osman Sabri; Cristal Kestelman, Adrián; Ayguadé Parra, Eduard; Valero Cortés, Mateo (2011)
    Conference report
    Restricted access - publisher's policy
    Many concurrent programs require some form of conditional synchronization to coordinate the execution of different program tasks. Programming these algorithms using transactional memory (TM) often results in a high ...
  • Nebelung: execution environment for transactional OpenMP 

    Milovanovic, M; Ferrer, Roger; Gajinov, Vladimir; Unsal, Osman Sabri; Cristal Kestelman, Adrián; Ayguadé Parra, Eduard; Valero Cortés, Mateo (2008-06)
    Article

    Future generations of Chip Multiprocessors (CMP) will provide dozens or even hundreds of cores inside the chip. Writing applications that benefit from the massive computational power offered by these chips is not going to ...
  • Supporting stateful tasks in a dataflow graph 

    Gajinov, Vladimir; Stipic, Srdjan; Unsal, Osman Sabri; Harris, Tim; Ayguadé Parra, Eduard; Cristal Kestelman, Adrián (Association for Computing Machinery (ACM), 2012)
    Conference report
