FLUKA for Mac OSX
G. Battistoni, INFN Milano

2. System tested Mac OS X Yosemite (now 10.10.3) 64-bit
fink as manager for software installation
gcc , includes gfortran
Fluka:
Development version fluka (march 2015)
Same version run in comparison under linux (Fedora bit gfortran 4.8.3)

3. Only problem in compilation $FLUKA/flutil/usbmax.c
Linux
#include <math.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <getopt.h>
#include <values.h>
#include <stdarg.h>
Mac
#include <math.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <getopt.h>
#include <limits.h>
#include <float.h>
#include <stdarg.h>
Not found in Mac (not safely identified in the usual path of includes)
Seem to be the right replacement for values.h

4. Many test cases considered
Large use of LATTICE…
(384x2x6 fibers 24x24 LYSO pyxels)
An example (INSIDE project)
Tracker device with 6 X-Y planes of scintillating fibers
0.05 mm pitch
Air
Proton beam
Pixellated LYSO crystal
Thick plastic scintllator

5. Output and Test results
Standard
USRBIN
User output
Detailed dump event by event of track history, energy depositions in each detector element
Test successful
(several cycles and events)
Identical history of random seeds in Linux and Mac
No difference at all in results between Mac and Linux version both in standard and user output (also same size of files)

6. Flair installation
Started from flair*tgz packages to be locally compiled
Tested versions: 2.1-0, and (the most recent one)
Available Gnuplot is v
Important:
Non positive experience with python from installers (*.dmg) downloaded from or similar!
Also python packages shoud be installed using fink
software goes into
/sw/lib/python2.7/site-packages
/sw/bin/python
The easy_install command from python setuptools has also to be used.
Notice: in mac-osx tkinter goes with python installation You will not find it explicitly with fink

7. Pythons packages Most important
Recently added (including dependencies) required by last version 2.1-3
(some trouble also under llnux…)
matplotlib-1.3.1
pytz
six py2.7
python_dateutil-2.2
PyOpenGL-3.0.2
tornado
wx-2.8-gtk2-unicode
mpl_toolkits
six.pyo
pyparsing
cffi
PIL
dateutil
Most important
Pillow py2.7
pydicom py2.7
numpy py2.7
gnuplot python interface
Doubts… see later

8. Graphical aspect identical to linux version

9. Use of geoviewer 1

10. Use of geoviewer 2

11. Use of geoviewer 3

12. Successfully tested features:
Input management
Help
Geometry viewing and editing
Picture exporting
Run control
Postprocessing of output files
Viewer
1D plots, 2D plots (w/o geometry superposition)
Compiling and linking
Calculator
Material database
Yet two unsolved issues remain…

13. Unsolved issue #1: 2D plots with geometry
Example: Shooting a He beam (in air) to a polythyrene flask and a water phantom
2D USRBIN plot without geoemetry
OK. Same as in linux version

14. Unsolved issue #1: 2D plots with geometry
Example: Shooting a He beam (in air) to a polythyrene flask and a water phantom
??? Notice that also the palette scale goes crazy
2D USRBIN plot WITH geoemetry
In linear Z scale
You just see a white plot
And geometry contours
There are problems in Gnuplot for mac (transparency seems to behave differently with respect to linux)
and/or in the python-gnuplot interface
Not yet understood

15. Unsolved issue #2: numpy with dicom?
Attempting to view a dicom slice an error message appears:
ValueError: all the input arrays must have same number of dimensions
Apparently due to numpy (scientific computing with Python)

16. Unsolved issue #2: numpy with dicom?

17. Conclusions
FLUKA under Mac OSX appears to work correctly giving the same results as in Linux.
A devel distribution for the collaboration could be shared.
A pro beta version could be distributed.
Flair for Mac has still a couple (at least) of things that should be understood and possibly solved. At present I am not able to do that, I’m afraid…
High level help needed (already some interactions with Vasilis occurred)

18. Added during the meeting
The problem of 2D plots with geometry superimposed has been solved in version 2.1-4
(V. Vlachoudis)
Set format “%g” in order to get exponential scale
