  3. LSF and GLOBUS • Metacomputing Infrastructure • Global scheduling local scheduling • GLOBUS+LSF at NASA • Discussions with other sites

  4. LSF Batch LSF Analyzer LSF MultiCluster LSF JobScheduler LSF Parallel LSF Make LSF Suite of Products LSF Base

  5. Load Information Interactive Jobs Batch Jobs LSF MultiCluster: Architecture Red Cluster Master Yellow Cluster Master

  6. Provides resource sharing: Separately managed sites Multiple departments/divisions in a large corporation Computing centre supporting many sites Multiple cooperating organisations Loosely connected sites Over long distance or slow links Across WAN with time differences While maintaining: Autonomy Each cluster has its own LSF administrators Each cluster sets its own policies Administrators of different clusters negotiate in setting up inter-cluster resource sharing policies Reliability The availability of one cluster does not affect another Communication failures between clusters does not cause job loss LSF MultiCluster

  7. Graphic User Interface LSF multi-cluster as integrator AIX SGI … ENEA: Software Conceptual Structure User programs & commercial code Load Leveler Telnet LSF AFS Geographical cross platform& File System SUN NT Linux Quadrics Compaq

  8. LSF customers • ENEA • CERN • Fermilab • SLAC • LANL • LLNL • LBNL

  9. Need for Enhanced Cooperation • Resource sharing between sites • User authentification • Secure job submit • Accounting ... what else?
