Round Table

Marco Cl.

• Gaudi: replacement for QMTest on its way

Roel

• Hlt and Moore releases took long (CMake and ROOT problems)
• ROOT bug reported but not top priority because we have a work around
• Phys required a new build
• Gerhard changes made Moore go faster (25% more throughput)

Marco Ca.: we need to check the memory usage with ROOT 6

Gloria

• Issues with the deployment of Gauss because of data packages that do not have the RPMs
• The RPM of Geant4 was missing the InstallArea/include directory. Fixed by Marco Cl. moving it to InstallArea/include
