      Architectural support for data-driven execution 

      Matheou, George; Evripidou, Paraskevas (2014)
      The exponential growth of sequential processors has come to an end, and thus, parallel processing is probably the only way to achieve performance growth. We propose the development of parallel architectures based on ...

      CacheFlow: A short-term optimal cache management policy for data driven multithreading 

      Kyriacou, Costas; Evripidou, Paraskevas; Trancoso, Pedro (2004)
      With Data Driven Multithreading a thread is scheduled for execution only if all of its inputs have been produced and placed in the processor's local memory. Scheduling based on data availability may be used to exploit ...

      CacheFlow: Cache optimizations for data driven multithreading 

      Kyriacou, Costas; Evripidou, Paraskevas; Trancoso, Pedro (2006)
      Data-Driven Multithreading is a non-blocking multithreading model of execution that provides effective latency tolerance by allowing the computation processor do useful work, while a long latency event is in progress. With ...

      A case for chip multiprocessors based on the data-driven multithreading model 

      Trancoso, Pedro; Evripidou, Paraskevas; Stavrou, Kyriakos; Kyriacou, Costas (2006)
      Current high-end microprocessors achieve high performance as a result of adding more features and therefore increasing complexity. This paper makes the case for a Chip-Multiprocessor based on the Data-Driven Multithreading ...

      Chip multiprocessor based on data-driven multithreading model 

      Stavrou, Kyriakos; Kyriacou, Costas; Evripidou, Paraskevas; Trancoso, Pedro (2007)
      Although the dataflow model of execution, with its obvious benefits, has been proposed for a long time, it has not yet been successfully exploited. Nevertheless, as traditional systems have recently started to reach their ...

      Combining compile and run-time dependency resolution in Data-Driven Multithreading 

      Arandi, Samer; Michael, G.; Evripidou, Paraskevas; Kyriacou, Costas (2012)
      Threaded Data-Flow systems schedule threads based on data-availability i.e. a thread can be scheduled for execution only after all its inputs have been generated by its producer threads. This requires that all data ...

      Combining pragmatics and intelligence in semantic web service discovery 

      Tamani, E.; Evripidou, Paraskevas (2007)
      In this paper we present an architecture that augments existing semantic-based web service discovery solutions. The idea is to combine principles from the semantic and pragmatic web in order for the web service selection ...
