Grid2Win: Porting of gLite middleware to Windows XP platform Dario Russo & Fabio Scibilia INFN – Catania 27.10.2006, Catania {Dario.Russo, Fabio.Scibilia}@ct.infn.it

gLite Architecture Grid Terminal Computing power Catania, Grid Industry Day, 27.10.2006 2

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 Is a 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 Catania, Grid Industry Day, 27.10.2006 3

Goals Presently on gLite This implies Porting of gLite to Windows 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 !

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 Worker Node GRIS sensors GSIFTP RFIO gLite client tools Prototype !!! To Be Done !!! Catania, Grid Industry Day, 27.10.2006 5

Grid2Win Graphical UI 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 Catania, Grid Industry Day, 27.10.2006 6

gLite Services Already Working on WinXP 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 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 Catania, Grid Industry Day, 27.10.2006 7

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 Catania, Grid Industry Day, 27.10.2006 8

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 !!! Catania, Grid Industry Day, 27.10.2006 9

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 !!! Catania, Grid Industry Day, 27.10.2006 10

Grid2Win GUI snapshots (4/5) Job Management A job is submitted just by double-clicking You can check job status and download job’s output just by double-clicking on the Job Identifier !!! Catania, Grid Industry Day, 27.10.2006 11

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 !!! Catania, Grid Industry Day, 27.10.2006 12

Future plans for Grid2Win CE Architecture Gatekeeper (Windows or Linux) Load Sharing Facility (LSF) as Local Resource Manager Mixed farm of WNs (WinXP/Linux) Milestones 20 November: Compiling of gLite worker nodes on Windows 1 more day: Linking of WinXP WNs to LSF 30 November: Integration of the first Windows/Linux mixed farm with the rest of the Grid 15 December: Compiling of the Gatekeeper on Windows. First completely Windows based CE Catania, Grid Industry Day, 27.10.2006 13

Summary and Conclusions gLite User Interface successfully ported on Windows GUI under development (Alpha release available!) We believe that this activity could open an entire new world for Windows and its applications on the Grid If there is any interest to collaborate with us we are willing to consider the new Microsoft Compute Cluster Server as a possible replacement of LSF as Local Resource Manager System Catania, Grid Industry Day, 27.10.2006 14
