3. OS X at a glance OS X platform is increasing in popularity amongst
developers and users on both the LHC experiments
at CERN and the Tevatron at Fermilab
Familiar Unix OS, no dual-booting, robust, stable
Easy to manage

4. Open source and Commercial applications used by Particle Physicists
1- AFS
2- Mathematica
3- GNU compilers: gcc 3.3 ( as options), others available
(g from Fink, g95 available)
5- Ichat
8-Major language
C, C++, Objective-C, Objective-C++, Java, Perl, Tcl, PHP,
Python & Ruby
7- RPM

5. AFS

6. Other general scientific software
xmgrace (Graph plotting program)
Latex and Lyx
Fugu (sftp/scp client with graphical interface)
Emacs both native to Aqua (the Mac windowing system) and X11
ImageMagick (not really physics, but useful for converting
diagrams between .ps and .jpg etc)

7. HEP Software: 1- General a- CERN Library b- Root d- Geant4
e- LHAPDF “Les Houches Accord Parton Density Function”
f- Hdcay
g- Pythia
h- ktjet (Code by Manchester)
i- ExHuME (Monte Carlo Generator Code by Manchester)
j-CPX+ (CPX SUSY code by Manchester)
k-pomwig (Monte Carlo Generator Code by Manchester)
l- HERWIG
2- Experiment specific

8. OS X and the experiments
LHC experiments and LCG show recent
development activities on OS X
Little effort by single individuals (even on
spare time)
ALICE: the whole offline software runs on
OS X CMS: Iguana, Orca, initial port of external libraries
ATLAS: CMT, Atlantis, Atlas distribution kit (based on CMT &
Pacman), single packages of the Athena framework
LHCb: Gaudi, Panoramix, Da Vinci
LCG: SEAL, PI, externals libraries on Xserve

10. Geant4 simulation toolkit
• Used to simulate particle interactions through matter
• Written in C++
• Software ported and tested on MacOS 10.3 with
gcc 3.3 compiler
–First-level porting for shared libraries in the last
release 6.2 of the toolkit
• Binary libraries distributed on CD (created and
maintained by SLAC Geant4 developers)
–Libraries also available on FINK (maintained by
user community)
• Fairly large (and growing) user community
• The platform will become soon officially supported

18. Summary
OS X is rapidly becoming accepted as an OS for HEP, but gaps still remain
