- CLHEP/Geometry: added move constructor and move assignment in Transform3D.
20 June 2019 - G.Cosmo
- Synchronised with CLHEP-2.4.1.2:
MixMaxRng: throw if seed is zero. Use throw instead of exit() elsewhere.
07 June 2019 - G.Cosmo

compilation option (default in Geant4).
16 March 2018 - G.Cosmo
- Synchronised with CLHEP-2.4.0.4.
07 March 2018 - G.Cosmo
- Removed kludge for Windows introduced in tag "clhep-V10-04-00" to
MinMaxRng.hh.
- Further simplified setup for thread-local storage and atomics, as
now all supported by c++11 in either clang or VC++.
06 March 2018 - G.Cosmo
- Enabled thread-local storage and atomics on Windows; added flag in
thread_local.h, use_atomic.h and atomic_in.h.
19 February 2018 - J.Madsen (clhep-V10-04-00)
- Fixed Windows MT data race in MinMaxRng.hh.
- Fixed warning C4293: '>>': shift count negative or too big, undefined behavior
in Ranlux64Engine on Windows
11 December 2017 - G.Cosmo
- MixMaxRng: fixed guard for assembly code in modadd() to protect
builds on 32-bit systems.
15 November 2017 - G.Cosmo
- MixMaxRng: fixed print_state() method to proper C++.
13 November 2017 - G.Cosmo
- Fixed shadowing warning in MixMaxRng.
09 November 2017 - G.Cosmo
- Updated MixMaxRng class to include latest C++ revision by K.Savvidy
based in MixMax-2.0. Replaced skipping coefficients optional set for
N=256 with N=240. Removed old C implementation files.
- Set MixMax as the default random number generator in HepRandom.
09 October 2017 - G.Cosmo
- Added missing DLL_API specification for static data member in Transform3D
class.

03 February 2017 - B.Morgan (clhep-V10-03-00)
- Set interface include directories on G4clhep{-static} targets
in CMakeLists.txt. This provides the needed interface to allow transparent
usage of internal/external CLHEP via targets and without needing to use
include_directories explicitly. Only set include paths in BUILD
interface for consistency with other targets.
04 November 2016 - G.Cosmo
- Updated to CLHEP-2.3.4.3.
- Fixed array initialisation in Evaluator static method function().
08 July 2016 - G.Cosmo
- Corrected value of SPECIALMUL in mixmax.h to correspond to exact formula
for N=17 (m=2^36+1).
10 May 2016 - G.Cosmo
- Updated to CLHEP-2.3.3.0.
- Corrected check for counter range in MixMaxRng::getState().
Avoid hard-coded constant for initialisation of VECTOR_STATE_SIZE in
MixMaxRng, to directly use actual value of "N" from mixmax.
02 May 2016 - G.Cosmo
- Added symbols 'us' and 'ps' for microsend and picosecond respectively
to SystemOfUnits.h and setSystemOfUnits.cc and converted all symbols and
constants from "static const" to "static constexpr".
28 April 2016 - G.Cosmo
- Restored skipping of sequences for safer setting of seeds in setSeeds()
in MixMaxRng. Changed number of N in mixmax to 17 (was 256) and provided
new skipping coefficients for the new value of N and for the case N=8.
25 April 2016 - G.Cosmo
- Use seed_spbox() for seeding MixMax with single seed.
21 April 2016 - G.Cosmo
- Refined fix for sequence skipping; make it optional by adding Boolean flag
argument (true by default) in seed_uniquestream() function in mixmax.cc to
force sequence skipping when setting seeds. Simplified code, removing
compilation guard flags.
Set flag to false by default in MixMaxRng wrapper and defined function
skipSequencesOnce() to optional instruct to apply skipping of sequences
at the next seeds setting.
20 April 2016 - G.Cosmo
- Updated to CLHEP-2.3.2.2:
* Utility (L.Garren <garren@fnal.gov>)
o Added use_atomic.h: use std::atomic when the compiler declares it
uses the C++11 standard.
* Random (W.D.Dagenhart <wdd@fnal.gov>)
o MixMaxRng.cc: the uncorrected code might not always yield independent
seeds.
If two threads execute numberOfEngines++ and after both finish that both
execute setSeed, then they will have the same seed. Fixed.
o Random.cc: there is a thread local variable of the type "defaults"
that contains two shared_ptr's in Random.cc. This causes an intermittent
problem on OSX. The complex objects containing the shared_ptr's have been
moved into a list of objects and the now the thread_local only contains a
simple pointer now that points into the list.
Use the new Utility/use_atomic.h header.
19 April 2016 - G.Cosmo
- Commented out sequence skipping from built-in table in mixmax.cc (undefined
flag SKIPISON), in order to avoid contention in multi-threaded jobs and
simplify seeding procedure. Removed use of obselete 'register' keyword.
- Minor code cleanup in MixMaxRng.
11 April 2016 - G.Cosmo
- Use simple loop for flatArray() in MixMaxRng; engine built-in function
turns out to be extremely slot and unefficient.
09 November 2015 - G.Cosmo
- Updated to CLHEP-2.3.1.1.
- Added MixMaxRng to Randomize.h.
30 October 2015 - G.Cosmo
- Fixed default seeding in MixMaxRng::setSeeds().
28 September 2015 - G.Cosmo
- Fixed compilation warning on gcc in mixmax.h for signed/unsigned comparison.
- Added reference to MixMaxRng.h.
25 September 2015 - G.Cosmo
- Added MixMaxRng to EngineFactory.
- Added copy-constructor and assignment operator to MixMaxRng.
- Replaced "#define N 256" with "static const unsigned int N = 256;"
in mixmax[.h.cc] and adapted code accordingly; commented out unused
cases for different values of N.
Fixes symbols clashes within CLHEP namespace.
18 September 2015 - G.Cosmo
- Disable thread_local and atomic c++11 features specific for Intel-icc
compiler in Utility module: thread_local.h, atomic_int.h.
Use settings related to gcc.
15 September 2015 - G.Cosmo
- Fixes by K.Savvidy to allow for porting on Intel-icc compiler and
Windows Visual Studio. Updated files: minmax[h.cc].
14 September 2015 - G.Cosmo
- Included changes by K.Savvidy to make MixMax support 32-bits platforms.
Updated files: minmax[h.cc], mixmax_skip_N256.icc.
25 August 2015 - G.Cosmo
- Added MixMax random engine classes implementing the "Matrix Generator of
Pseudorandom Numbers", as described in J. Compt. Phy. 97, 573 (1991).
Added files:
o MixMaxRng[h.cc]: CLHEP interface class to MixMax generator.
o minmax[h.cc]: C++ translation/adaptation of the MixMax generator.
o mixmax_skip_N256.icc: table of skipping coefficients for MixMax (N=256).
19 August 2015 - M.Maire
- Added liter and its sub units to SystemOfUnits.h: liter, L, dL, cL, mL.
12 August 2015 - G.Cosmo
- Use std::shared_ptr in random classes instead of internal Boost-derived
implementation.
- Corrected RandExpZiggurat to use shared_ptr as for all other distributions.
- Utility module: removed Boost derived implementation of shared_ptr and
weak_ptr, now typedefs to c++0x standard std::shared_ptr and std::weak_ptr
respectively. Removed no longer used type_traits.h header.
7 August 2015 - G.Cosmo
- Temporarly commented out assertion in memory.h, in view of full transition
to C++11 for use of shared_ptr et al..
6 August 2015 - G.Cosmo
- Enable thread_local and atomic c++11 features for Intel-icc compiler
in Utility module: thread_local.h, atomic_int.h.

20 September 2011 - G.Cosmo
- Added missing export statements for static symbols required for DLL build.
22 June 2011 - B.Morgan
- CMakeLists.txt : Added the CLHEP include directory to
GEANT4_BUILDTREE_INCLUDE_DIRS so that its visible from the build tree if
we use the internal CLHEP.
20 June 2011 - B.Morgan
- CMakeLists.txt : Install CLHEP headers to
CMAKE_INSTALL_INCLUDEDIR/PROJECT_NAME in line with new standard install
directory structure.
14 June 2011 - B.Morgan
- CMakeLists.txt : Build G4clhep through standard GEANT4_LIBRARY_TARGET
macro. Keep installation of headers as is.
13 June 2011 - B.Morgan
- CMakeLists.txt : Added use of new CMAKE_INSTALL_XXX variables to control
installation of libraries and headers, and add exported libraries to a
global property as per other Geant4 targets. Header paths are not added to
a global property though because these can be internal or external, so
we handle them higher up when generating the configuration files.
2 June 2011 - B.Morgan
- CMakeLists.txt : NEW file adding CMake build of 'G4clhep'
Implemented as a single CMakeLists.txt because special handling of
the nested header structure of CLHEP is needed at install time.
1 June 2011 - G.Cosmo
- Fixed trivial compilation warnings on gcc-4.6.0 in NonRandomEngine.h
and Ranlux64Engine.cc for parameters defined but not used.
24 May 2011 - G.Cosmo
- Added missing files in CLHEP built-in module.
Allow for generation of DLL library on Windows for it.
11 May 2011 - G.Cosmo
- Including a subset of CLHEP classes imported from version CLHEP-2.1.0.1.
- Modifications applied vs. original CLHEP classes:
* Removed dependency on internal CLHEP "defs.h" configuration header;
the Geant4 built-in module for CLHEP follows the Geant4 build scheme.
* Adopt "std" namespace for standard mathematical functions, where needed.
* Removed dependency on ZM exceptions and replaced with "cerr" printouts
where necessary.
* Renamed following files for coherency and standard:
o Inlined code *.src to *.icc and moved to includes set;
o DualConv.hh to DualConv.h.
* Use coherent inclusion scheme also for internal headers/data/inline-code,
where applicable.
* Use of standard WIN32 compiler flag where applicable.
* Cleared source code of de-activated debug blocks and minor cleanup,
where applicable.
* Rename of final CLHEP library produced, from 'CLHEP' to 'g4clhep'.
