      Adaptive noise canceling and edge detection in images using PVM on a NOW 

      Mylonas, S. A.; Trancoso, Pedro; Trimikliniotis, Michael (IEEE, 2000)
      A method for the processing of digital images using a two-dimensional LMS adaptive filter for noise reduction and subsequent edge detection is presented. This was implemented on a Parallel Virtual Machine (PVM) consisting ...

      Linearizability in the presence of drifting clocks and under different delay assumptions 

      Eleftheriou, Maria; Mavronicolas, Marios (1999)
      The cost of usingmessag e-passing to implement linearizable read/write objects for shared memory multiprocessors with drifting clocks is studied. We take as cost measures the response times for performingread and write ...

      A local search mechanism for peer-to-peer networks 

      Kalogeraki, Vana; Gunopulos, Dimitrios; Zeinalipour-Yazdi, Constantinos D. (2002)
      One important problem in peer-to-peer (P2P) networks is searching and retrieving the correct information. However, existing searching mechanisms in pure peer-to-peer networks are inefficient due to the decentralized nature ...

      Trace processors 

      Rotenberg, Eric; Jacobson, Quinn; Sazeides, Yiannakis; Smith, Jim (IEEE Comp Soc, 1997)
      Traces are dynamic instruction sequences constructed and cached by hardware. A microarchitecture organized around traces is presented as a means for efficiently executing many instructions per cycle. Trace processors exploit ...
