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

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
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,

4. 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 !

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
Worker Node
GRIS sensors
GSIFTP
RFIO
gLite client tools
Prototype !!!
To Be Done !!!

6. 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

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

8. 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,

9. 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,

10. 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,

11. 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,

12. 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 !!!

13. 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,

14. 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
