Eric van Herwijnen March 10th 2005 Gaucho status report Eric van Herwijnen March 10th 2005

Who? Philippe Vannerem (left last year) Eric van Herwijnen (CERN, come to me if something doesn’t work) Clara Gaspar (CERN) Pere Mato (CERN) Helder Lopes (Rio) Miriam Gandelman (Rio) Fri Jan 21st 2005 Gaucho Status Report

Objectives Control and monitor trigger (Gaudi) processes online PVSS Processes are nodes in ECS hierarchy (FSM) Download appropriate sw from configuration database & send values to application manager Integrated with farm control system Send monitoring data (counters, rates, histograms, status, error messages) to ECS Combine information from individual CPUs Prepare for Real Time Trigger Challenge Fri Jan 21st 2005 Gaucho Status Report

PVSS PVSSDim Server Dim DNS running on a controls PC Gaucho_dll (DIM server) Gaudi job n Gaudi jobs running on n Subfarm PCs

Gaucho production status v1r1 documented, packaged and released http://lhcb-comp.web.cern.ch/lhcb-comp/ECS/Gaucho/ LHCB note 2004-96 used by trigger group System works using a real L1 DaVinci algorithm (F. Legger, Lausanne) Fri Jan 21st 2005 Gaucho Status Report

Current developments Integration with Gaudi done by RIO (Helder Lopes): New MonitorSvc implemented, IMonitorSvc moved into GaudiKernel v18r0 Automatic cleanup on algorithm desctruction New declareInfo method in Gaudi base class Code being tested Select algorithms and properties to run Display and set algorithm properties Traverse Histogram Store and publish histograms on the fly New RootViewer to view histograms with Root PVSS panels updated Fri Jan 21st 2005 Gaucho Status Report

Use taskmanager for jobsubmission instead of plink/ssh Route messages to PVSS instead of cmd window Fri Jan 21st 2005 Gaucho Status Report

Check Root viewer on Linux Study how it could be used (replace PVSS trending tool)

Root viewer Display Hugo Ruiz’ pull histograms (see yesterday’s talk) Run a root macro, publish results back to PVSS Fri Jan 21st 2005 Gaucho Status Report

Gaudi State Machine New option values are given back to DimPropServer Some options are taking into account, others not More important to be able to select algorithms and options before a job starts Find a way to load algorithms into an always running Gaudi shell Fri Jan 21st 2005 Gaucho Status Report

Browsing of transient store No need to rely on the user to publish objects Can browse the store and display its contents Implemented for histograms Fri Jan 21st 2005 Gaucho Status Report

Gaucho job list Test and integrate Helder’s new implementation of the MonitorSvc Package and document current developments Use Bologna’s TaskMgr to start Gaudi On windows, route the Gaudi output to the PVSS message window (on Linux this happens by default) Select algorithms and options and download to a Gaudi shell Use configuration database Fri Jan 21st 2005 Gaucho Status Report
