E-science grid facility for Europe and Latin America GridwWin: porting gLite to run under Windows Fabio Scibilia – Consorzio COMETA 30/06/2008

Catania (Italy), Joint EELA/EGEEIII Tutorial for Trainers, – Computing resource Grid Terminal Preliminars: gLite architecture

Catania (Italy), Joint EELA/EGEEIII Tutorial for Trainers, – 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 Preliminars: Computing Element

Catania (Italy), Joint EELA/EGEEIII Tutorial for Trainers, – Presently on gLite –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 ! Targets

Catania (Italy), Joint EELA/EGEEIII Tutorial for Trainers, – 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 Porting strategy

Catania (Italy), Joint EELA/EGEEIII Tutorial for Trainers, – 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 –Torque/MAUI (PBS)  Linux head node  Windows XP Worker Nodes –Microsoft Compute Cluster Server (CCS)  Linux auxiliary node  Windows XP CCS farm Done !!! Prototype !!! Prototype DONE!!! What is already done

Catania (Italy), Joint EELA/EGEEIII Tutorial for Trainers, – Grid Security Infrastructure –Credentials management with VOMS extensions  voms-proxy-* commands Workload Management –Job submissions and output retrieving  glite-wms-job-* commands  edg-job-* commands File Transfer –Secure transfer with credential management  GSIFTP (globus-url-copy)  RFIO commands (rf-*) Data Management –File Catalogue Browsing  lfc-* command –Data Movement and Replication  lcg-* commands Information System –Command lines  lcg-info  lcg-infosites –Grid2Win GUI  LDAP Explorer integrated in our GUI Status of porting

Catania (Italy), Joint EELA/EGEEIII Tutorial for Trainers, – Computing Element (CE) –Scientific Linux –PBS server Worker Nodes (WNs) –MS Windows XP –PBS mom –gLite clients –We are providing for an installer Porting PBS as CE on Windwos

Catania (Italy), Joint EELA/EGEEIII Tutorial for Trainers, – CCS –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 Integrating CCS as native CE
