Charge to the Software Review Committee
=======================================
The CALICE collaboration is studying calorimetry for ILC
detectors. The collaboration has acquired a large dataset 
from calorimeter beam tests in 2006 and 2007 and expects to 
approximately double this during 2008. The total dataset so
far is around 300M events, occupying 25TBytes. The dataset
has significant complexity, being taken at different locations
with differing beam conditions, energies and detectors.

The ILC detectors have been charged with producing Letters 
Of Intent by Oct 2008 and initial Engineering Design Reports 
are expected by 2010. Hence, it is imperative that the 
collaboration extracts results from these data and publishes
them in a timely manner. However, it is also expected that the
final analyses of all the data will not be complete until three
or four years from now.

The main aim of the data analysis is fourfold. Firstly, it is
to measure the performance of the prototype calorimeters used in
the beam tests. Secondly, it is to compare Monte Carlo models 
with data so as to measure the degree of accuracy of the models.
Thirdly, it is to apply the knowledge gained so as to optimise 
the ILC detector calorimeters with a verified, realistic and
trustworthy simulation. Fourthly, it is to develop calorimeter 
jet reconstruction algorithms and test them on real data as well
as simulation.

A significant offline software structure has already been put together
to accomplish these aims, built on a previously determined conceptual
model. The purpose of the review is to examine the implementation of
this structure and comment on whether it does (or can in future) 
meet the aims of the collaboration. Some important points are

o If missing or ineffective areas can be identified, the review
  should suggest possible solutions or alternatives.
o Recommendations to streamline the reconstruction, simulation or
  analysis of the data, to save effort or time, should be made. 
o The review should examine how well suited is the structure for
  the connection to the longer term detector studies and the
  development of jet reconstruction algorithms.
o Comments on whether the organisational structure is appropriate
  would be useful.

There are limited numbers of people involved in the collaboration
and so any recommendations from the review need to made with this
in mind. In particular, some aspects of the software structure, 
such as the use of general ILC software, are probably too widely
used to be realistically changed at this point. However, as a major
user of the central ILC software, our experience should be useful
to help improve it. If the review identifies constraints or bottlenecks
arising from the use of this central software, comments on these would
very welcome.
