      Exploring graphics processor performance for general purpose applications 

      Trancoso, Pedro; Charalambous, Maria (2005)
      Graphics processors are designed to perform many floating-point operations per second. Consequently, they are an attractive architecture for high-performance computing at a low cost. Nevertheless, it is still not very clear ...

      Extrinsic and intrinsic text cloning 

      Kleanthous, Marios M.; Sazeides, Yiannakis; Dikaiakos, Marios D. (2012)
      Text Cloning occurs when a processor is storing in its shared caches the same text multiple times. There are several causes of Text Cloning and we classify them either as Extrinsic or Intrinsic. Extrinsic Text Cloning can ...

      FAST: a functional algorithm simulation testbed 

      Dikaiakos, Marios D.; Rogers, Anne; Steiglitz, Kenneth (Publ by IEEE, 1994)
      In this paper we extend the practical range of simulations of parallel executions by what we call 'functional algorithm simulation,' that is, simulation without actually performing most of the numerical computations involved. ...

      Fault detection and recovery in a data-driven real-time multiprocessor 

      Farquhar, William G.; Evripidou, Paraskevas (Publ by IEEE, 1994)
      This paper introduces the mechanisms required to perform fault detection and recovery in the DART multiprocessor architecture. The DART multiprocessors uses prioritized data-driven scheduling to ensure that multiple hard ...

      Fault-tolerant computation in groups and semigroups: Applications to automata, dynamic systems and Petri nets 

      Hadjicostis, Christoforos N.; Verghese, G. C. (2002)
      The traditional approach to fault-tolerant computation has been via modular hardware redundancy. Although universal and simple, modular redundancy is inherently expensive and inefficient. By exploiting particular structural ...
