The objective of the MONARC project is to identify baseline
computing models that could provide viable solutions meeting the
data analysis needs of LHC experiments. A powerful and flexible
set of simulation tools has been developed to model the performance of
distributed computing resources for a set of reconstruction and
analysis tasks. In this report we report the validation of the
simulation tools using the testbed environment using Objectivity/DB
over LAN and WAN.
The simulation tools are based on Java, and the resource utilization
such as CPU, disk and network are calculated with a method called
"process oriented discrete event simulation". The detail of the
simulation tool has been described elsewhere. A set of testbeds have
been set up within the MONARC project in places like CERN, KEK,
INFN, Caltech, and SLAC, which are interconnected with various
kinds of wide area networks ranging from dedicated satellite ATM
PVC circuits to QoS services. Several example HEP analysis codes
based on Objectivity/DB have been developed and tested over these
testbeds. Measured performance results were then compared to the
simulation to validate behaviors of the various components in the tools.
