PARALLEL AND DISTRIBUTED COMPUTING RESEARCH GROUP

Our research group performs research of computing problems whose computational or memory complexity requires deployment of many processors or stand-alone computers. We focus on the modern parallel and distributed computing systems consisting of thousands of computing nodes. We are interested both in data structures and algorithms in selected application domains and in research of system architectures of large-scale high-performance computing systems, such as computational grids, computer clusters, and massively parallel machines.
 

RESEARCH AREAS

  • Algorithms for GPGPU computing platforms
  • Architecture of non-dedicated computing clusters
  • Distributed algorithms for P2P clusters
  • Distributed task scheduling in computational grids
  • High-performance computing with very large sparse matrices
  • Memory and storage representation of sparse matrices
  • Multithreaded microarchitectures
