  |  | Distributed BELLE Analysis Framework |  
    Institute of Particle and Nuclear Studies, KEKComputing Research Center, KEKDepartment of Physics, University of Tokyo Speaker: 
Takeo HiguchiWe are developing a new event processing framework for the data analysis at
the BELLE experiment. It is an extension to
the existing "Belle AnalysiS Framework" reported at CHEP97 
which features 1) the module-and-path structure, 2) the dynamic link of 
modules, and 3) the parallel processing capability on SMP servers. 
With this extension, the parallel processing capability is improved so 
that it can make use of not only CPUs on an SMP server 
but also those on distributed
workstations or PCs connected through a network.  
The number of event processing CPUs is dynamically changed
to optimize the resource usage. The resource
management is done by a centralized resource daemon program which
monitors a global pattern of the CPU load and I/O speed in the
computing facility. The detail of the design of the framework is
discussed at the conference.
