Presentation Transcript

  1. Grid2Win: Porting of gLite middleware to Windows XP platform • Fabio Scibilia on behalf of the Grid Group • INFN – Catania

  2. gLite Architecture Grid Terminal Computing power

  3. More on Computing Elements (CE) • Local Resource Manager (LRMS) • It is NOT a Grid component • Local administration • Dispatches job across Worker Nodes according to local policies • Accessed by local users • Computing Element • Service oriented • Exports computing power of the LRMS to grid users • Gatekeeper • Access point of the CE • Manages one or more job queues • Transparent interface to the LRMS • Worker Nodes • More than one (cluster) • Execute both local jobs and grid jobs To execute grid jobs, a specific environment must be set

  4. Goals • Presently on gLite • Grid users use the gLite middleware from Linux-based User Interfaces via CLI • (almost) All gLite resources are Linux-based • This implies • Grid users need to be trained • Only Linux-based applications can be deployed onto the Grid • Porting of gLite to Windows • User Interface • Computing Element (farm) new users come in to the grid ! windows applications can run on the grid !

  5. gLite porting on Windows Done !!! • User Interface • Client tools • Grid Security Infrastructue (GSI) • Workload Management Service (WMS) • Logging and Bookkeeping (L&B) • Data Management Service (DMS) • Information System (BDII) • Grid2Win Graphical User Interface • Computing Element • Gatekeeper • Grid Resource Information Index (GRIS) server • PBS as Local Resource Manager • Worker Node • GridIce sensors • GSIFTP client • gLite client tools Prototype !!! Done with PBS!!!

  6. Grid2Win GUI Prototype • Grid2Win GUI • wxWindows • Cross platform • Open source • Indipendent of underlying CLI • Installer 11Mbytes (including the cygwin DLL) • gLite Command Line Interface • Recompiled via Cygwin tools under Windows XP • Cygwin • Emulates POSIX environment on Windows • Only the Cygwin DLL must be installed Platform independent

  7. Grid2Win CE on PBS • Computing Element (CE) • Scientific Linux • PBS server • Worker Nodes (WNs) • MS Windows XP • PBS mom • gLite clients • We are providing for an installer

  8. Grid Security Infrastructure Credentials management with VOMS extensions voms-proxy-* commands Workload Management Job submissions and output retrieving glite-wms-job-* commands File Transfer Secure transfer with credential management GSIFTP (globus-url-copy) RFIO commands (rf*) Data Management File Catalogue Browsing lfc-* command Data Movement and Replication lcg-* commands Information System lcg-info lcg-infosites LDAP Explorer integrated within Grid2Win GUI PBS based CE gLite Services Already Working on WinXP

  9. Grid2Win GUI snapshots (1/5) • GSI credentials • Auto detection of the validity of the stored proxy • Generation of a new stored proxy via the insertion of the passphrase • Virtual Organization Membership Service (VOMS) extensions support

  10. Grid2Win GUI snapshots (2/5) File Catalogue browsing !!! Local file system explorer Grid File Catalogue explorer (LFC) You can navigate the remote Grid File Catalogue as it was local !!!

  11. Grid2Win GUI snapshots (3/5) Upload/download of grid files You can copy and paste a file from the local explorer to the catalogue browser and viceversa. Drag & drop is under development !!!

  12. Grid2Win GUI snapshots (4/5) A job is submitted just by double-clicking Job Management You can check job status and download job’s output just by double-clicking on the Job Identifier !!!

  13. Grid2Win GUI snapshots (5/5) Information Index (BDII) Navigation You can navigate the remote Information Index (II) as you navigate any other local information tree !!!

  14. Next steps • Computing Power • Porting Windows Compute Cluster Server (CCS) to the Grid • Porting gLite CE to Windows • Improving the GUI • Implementing the rest of the menu • Adding functionalities • Creating graphical JDL editors

  15. Grid2WinDemo Grid2Win UI Demo
