3. 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

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

5. Gaucho production status
v1r1 documented, packaged and released
LHCB note
used by trigger group
System works using a real L1 DaVinci algorithm (F. Legger, Lausanne)

6. 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

8. Use taskmanager for jobsubmission instead of plink/ssh
Route messages to PVSS instead of cmd window

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

12. Root viewer Display Hugo Ruiz’ pull histograms (see yesterday’s talk)
Run a root macro, publish results back to PVSS

15. 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

Gaucho Status Report

18. 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

Gaucho Status Report

19. 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
