  1. Grid and SCIEnce Semeniouk Igor LLR, Ecole Polytechnique Atelier de projet I3 SCIEnce

  2. Why Grid Early Grid pioneers found that • too hard to keep track of authentication data (ID/password) across institutions • too hard to monitor system and application status across institutions • too easy to leave "dangling" resources lying around, reducing system robustness • too many ways to submit jobs • too many ways to store, access, and ultimately manage distributed data. Atelier de projet I3 SCIEnce Semeniouk Igor, LLR

  3. Grid Architecture in a Nutshell Atelier de projet I3 SCIEnce Semeniouk Igor, LLR

  4. Middleware and GRIDS • Middleware • Globus Toolkit, Xgrid, Sun Grid, … • CORBA, Condor, RPC, … • User Identification • Certificate, password, Kerberos, … • GRIDs • LCG, EGEE, NorthGrid, … Atelier de projet I3 SCIEnce Semeniouk Igor, LLR

  5. Globus Toolkit GT-4 • Certificates for User and Services • Tools for job submission • Web Services • Data moving and data location • Service discovery • Monitoring • VO Support • Resource Broker • Data replication CA IS UI CE Atelier de projet I3 SCIEnce Semeniouk Igor, LLR

  7. Distributed Programming Frameworks • NetSolve/GridSolve - NetSolve/GridSolve is an RPC-based library for executing solver code on Grid resources. • Ninf-G - Ninf-G allows existing programming libraries to be used in a distributed fashion on a Grid using the RPC framework. • MPICH-G2 - MPICH-G2 is a Grid-enabled implementation of the popular MPI (Message Passing Interface) framework • Condor-G, DAGman - Condor-G and DAGman can be used to execute complex workflows (consisting of multiple independent or related jobs) using Grid compute resources via GRAM or Condor.
