Query: Supervision of the ATLAS High Level Trigger System   The ATLAS High Level Trigger (HLT) system provides software-based event
selection after the initial LVL1 hardware trigger. It is composed of two
stages, the LVL2 trigger and the Event Filter. The HLT is implemented as
software tasks running on large processor farms. An essential part of the HLT
is the supervision system, which is responsible for configuring, coordinating,
controlling and monitoring the many hundreds of processes running in the HLT. A
prototype implementation of the supervision system, using tools from the ATLAS
Online Software system is presented. Results from scalability tests are also
presented where the supervision system was shown to be capable of controlling
over 1000 HLT processes running on 230 nodes.
