      Partitioned Global Address Space (PGAS) languages appeared to address programmer productivity in large scale parallel machines. However, fine grain accesses on shared structures have been identified as one of the main ...
    • Combining static and dynamic data coalescing in unified parallel C 

      Alvanos, Michail; Farreras Esclusa, Montserrat; Tiotto, Ettore; Amaral, José Nelson; Martorell Bofill, Xavier (2015-02-19)
      Article
      Open Access
      Significant progress has been made in the development of programming languages and tools that are suitable for hybrid computer architectures that group several shared-memory multicores interconnected through a network. ...
    • Improving communication in PGAS environments: Static and dynamic coalescing in UPC 

      Alvanos, Michail; Farreras Esclusa, Montserrat; Tiotto, Ettore; Amaral, José Nelson; Martorell Bofill, Xavier (ACM, 2013)
      Conference report
      Restricted access - publisher's policy
      The goal of Partitioned Global Address Space (PGAS) languages is to improve programmer productivity in large scale parallel machines. However, PGAS programs may have many fine-grained shared accesses that lead to performance ...
    • Improving performance of all-to-all communication through loop scheduling in PGAS environments 

      Alvanos, Michail; Tanase, Gabriel; Farreras Esclusa, Montserrat; Tiotto, Ettore; Amaral, José Nelson; Martorell Bofill, Xavier (ACM, 2013)

    • Optimization techniques for fine-grained communication in PGAS environments 

      Alvanos, Michail (Universitat Politècnica de Catalunya, 2013-12-10)
      Doctoral thesis
      Open Access
      Partitioned Global Address Space (PGAS) languages promise to deliver improved programmer productivity and good performance in large-scale parallel machines. However, adequate performance for applications that rely on ...
    • Reducing compiler-inserted instrumentation in unified-parallel-C code generation 

      Alvanos, Michail; Amaral, José Nelson; Tiotto, Ettore; Farreras Esclusa, Montserrat; Martorell Bofill, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Conference report
      Restricted access - publisher's policy
      Programs written in Partitioned Global Address Space (PGAS) languages can access any location of the entire address space via standard read/write operations. However, the compiler have to create the communication mechanisms ...
    • Using shared-data localization to reduce the cost of inspector-execution in unified-parallel-C programs 

      Alvanos, Michail; Tiotto, Ettore; Amaral, José Nelson; Farreras Esclusa, Montserrat; Martorell Bofill, Xavier (2016-05-01)
      Article
      Open Access
      Programs written in the Unified Parallel C (UPC) language can access any location of the entire local and remote address space via read/write operations. However, UPC programs that contain fine-grained shared accesses can ...
