Gri2Win: Porting gLite to run under Windows XP Platform Fabio Scibilia on behalf of Dario Russo INFN - Catania Scuola INFN su aspetti pratici del grid computing Trieste, 1-12 Dic. 2008 Scuola INFN, Trieste, 1-12 Dic. 2008 - 1

Scuola INFN, Trieste, 1-12 Dic. 2008 - 2 gLite Architecture Grid Terminal Computing power Scuola INFN, Trieste, 1-12 Dic. 2008 - 2

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. 2008 - 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 ! Scuola INFN, Trieste, 1-12 Dic. 2008 - 4

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 !!! Scuola INFN, Trieste, 1-12 Dic. 2008 - 5

Scuola INFN, Trieste, 1-12 Dic. 2008 - 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 Scuola INFN, Trieste, 1-12 Dic. 2008 - 6

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*) Scuola INFN, Trieste, 1-12 Dic. 2008 - 7

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. 2008 - 8

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 Scuola INFN, Trieste, 1-12 Dic. 2008 - 9

Scuola INFN, Trieste, 1-12 Dic. 2008 - 10 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 ?)
