Clustering Technologies

What makes a bunch of computers on a network to become a computational cluster:

  • Single system Image (SSI).
    For example, OpenMosix. SSI is smart system software that spreads operating system functions across systems and involves modifications of the Linux kernel.


  • Single System Environment (SSE) A smart system software that runs in user space as layered service. SSE includes, for example:
      API libraries for programming, such as PVM and MPI
      Queue scheduling system (for example, LSF, Condor, PBS and Grid Engine )

    Examples of computational software utilizing MPI:

    FLUENT (Fluid Dynamics and Heat transfer)
    GASP (Gas Dynamics)
    AMBER (Molecular dynamics)
    NAMD (Molecular dynamics)
    GROMACS (Molecular dynamics)
