4.1.2 Simulation package development and support

... The role and support of FLUKA (requested by three experiments) needs to be further clarified and agreed on by CERN/IT, CERN/EP, the CERN Director responsible for Scientific Computing, the experiments and the authors.

4.1.6 Support for software and future evolution

... Most of the LHC experiments stated that they would like to see ROOT officially supported by CERN. ... The majority of the panel suggested that CERN seriously consider taking on ROOT core-team support as a mainline activity.

5.1.3 Operating Systems and Persistency solutions

... In what concerns Operating Systems, there is already a well-established trend towards one single Unix-like system, namely LINUX, or at most two, consisting of LINUX and one commercial UNIX OS. There are in fact good arguments to have a second platform for code and result verification.

6.5.3 Additional demands on CERN for human resources

... there are benefits in maintaining effort for parallel, complementary approaches in a very limited set of cases. Simulation, object persistency and analysis/visualization are considered to be three such cases.

For simulation, it would be beneficial to be able to make cross-checks between two different Monte-Carlo programs and the panel supported the proposal made by the Software Project panel in Chapter 4.1.2 above that, in addition to ongoing support for Geant4, the role and support of FLUKA should be clarified and agreed. It is estimated that one additional permanent CERN-resident person would be enough to help the FLUKA authors to provide support for the program and to make, in due course, a release of the code. The panel thus proposes that a CERN staff member be allocated to this task.

7 OVERALL CONCLUSIONS AND RECOMMENDATIONS
7.2 Software

... along with the introduction of CERN support for FLUKA and ROOT.
