  1. NetSolve / GridSolve By Milan Novakovic, Steven Morgan

  2. What is NetSolve? • A Distributed system... Duh • Aimed at helping scientists find a wide range of helpful tools

  3. Historically • Optimized for specific platforms • No convenient interface • Tools are rarely freely available: MATLAB and Mathematica

  4. Overview • Developed at the University of Tennessee. • Set of loosely connected machines • Heterogeneous environment i.e., the machines of different architectures, OSs and internal data representations can participate at the same time NetSolve

  5. Grid Middleware

  6. Status on NetSolve • Official release of NetSolve 2.0 in July, 2003 • Rebranded to GridSolve • Latest version release 0.19.1 in December 2008

  7. Recent Additions • Hardware/Software server transparency • Dynamic server • Octave support • Condor-G support • Distributed Storage Interface • GridRPC • Interface Definition Language • Cygwin/Mac OSX support • VisPerf Monitor

  8. NetSolve Agents

  9. NetSolve Agents Maintains index of computational resources & their characteristics Accepts requests from clients and dispatches them to the best-suited server

  10. Best suited? • Keeps track of computational resource status • Servers register their capabilities by PDF • Designed to optimize resource utilization • Tracks performance metrics of the servers

  11. NetSolve Servers • Each server is a computational resource • Uniform access to software • Functionalities extendable at will

  12. Machine-independent description language • Compiled by NetSolve tools into computational modules • Pre-written for FitPack, ItPack, MINPACK, FFTPACK, LAPACK, BLAS, QMR, ScaLAPACK

  13. Fault Tolerance • A NetSolve system is ELASTIC • Mechanism used is “retry”

  14. Contributions Drawbacks One of the earlier Grid computing systems, influenced a lot of later work Machine-independent systems Bringing together computational resources across a variety of hardware AND software Ease of use across different libraries Resource optimization What can this HW/SW package do BEST Load-balancing Very dated information Lack of performance metrics Lack of comparison against other systems Improvements • Some actual data statistics would be nice • Further in-depth analysis regarding NetSolve’s ability to optimize the system by swapping processes amongst better suited hardware

  15. Questions!
