gLite Architecture
Grid Terminal
Computing power
Scuola INFN, Trieste, 1-12 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
Scuola INFN, Trieste, 1-12 Dic

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
Monitoring
Grid Resource Information Index (GRIS) server
Torque/MAUI (PBS)
Linux head node
Windows XP Worker Nodes
Microsoft Compute Cluster Server (CCS)
Linux auxiliary node
Windows XP CCS farm
Release Candidate
Done !!!
Nearly Done !!!

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
Scuola INFN, Trieste, 1-12 Dic

7. Status of the porting of the UI
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
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*)

8. Porting PBS based CE to Windows XP
Computing Element (CE)
Scientific Linux
PBS server
Worker Nodes (WNs)
MS Windows XP
PBS mom
gLite clients
We are providing for an installer
Scuola INFN, Trieste, 1-12 Dic

9. Integrating CCS into gLite a novel CE
Microsoft CCS farm with a head node an more worker nodes
Auxiliary Nodes
Globus Gatekeeper (Linux)
Service interface to the grid
CCSJob Client Server
To put in communication the Gatekeeper (Linux) with the CCS head node (Windows)
To call CCS primitives
SSL channel

Next steps
Grid2Win
Refactoring of some pieces of the code
Adding many features
Writing a Windows native GUI
CCS based CE
Complete the integration
Deploy the first CCS based CE on our GILDA testbed
Removing the need for the auxiliary node by porting the Gatekeeper to Windows XP
Creating a proper installer
Storage Element
Porting GSIFTP daemon
Porting some MSS system (DPM ?)
