      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
      Open Access
      With the recent switch in the design of general purpose processors from frequency scaling of a single processor core towards increasing the number of processor cores, parallel programming became important not only for ...
    • 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 

      Gajinov, Vladimir; Stipic, Srdjan; Eric, Igor; Unsal, Osman Sabri; Ayguadé Parra, Eduard; Cristal Kestelman, Adrián (2015-06-01)
      Article
      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 ...
    • 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)

    • 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
      Restricted access - publisher's policy
      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
      Restricted access - publisher's policy
      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 ...
    • Practical experience with Nebelung: the runtime support for transactional memory and OpenMP 

      Milovanovic, Milos; Ferrer, Roger; Gajinov, Vladimir; Unsal, Osman Sabri; Cristal Kestelman, Adrián; Ayguadé Parra, Eduard; Valero Cortés, Mateo (2007-08)
      External research report
      Open Access
      Transactional Memory (TM) is a key future technology for emerging many-cores. On the other hand, OpenMP provides a vast established base for writing parallel programs, especially for scientific applications. Combining TM ...
    • QuakeTM: Parallelizing a complex serial application using transactional memory 

      Gajinov, Vladimir; Zyulkyarov, Ferad; Unsal, Osman Sabri; Cristal Kestelman, Adrián; Ayguadé Parra, Eduard; Harris, Tim; Valero Cortés, Mateo (2008-11)
      External research report
      Open Access
      'Is transactional memory useful?' is the question that cannot be answered until we provide substantial applications that can evaluate its capabilities. While existing TM applications can partially answer the above question, ...
