2. gLite Architecture Grid Terminal Computing power
Tutorial per Utenti, Università di Palermo, 10th-12th Dic

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

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 !

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

6. Grid2Win GUI Prototype Grid2Win GUI gLite Command Line Interface
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
