|
|---|
| 12 | o Configuration:
|
|---|
| 13 | -------------
|
|---|
| 14 | - Specific setups:
|
|---|
| 15 | o Linux-g++.gmk: added assignment 'CC := gcc' for default 'cc' compiler.
|
|---|
| 16 | o SUN-CC.gmk: removed -L/usr/lib path specification from LOADLIBS
|
|---|
| 17 | definition.
|
|---|
| 18 | o AIX-xlC.gmk: updated for porting on AIX with xlC 6.0 (unsupported).
|
|---|
| 19 | o WIN32-g++.gmk: updated setup to compile with -ansi and gcc-2.95.3
|
|---|
| 20 | for most recent versions of CygWin (unsupported).

|---|
| 21 | o Darwin-g++.gmk: updated setup to support MacOS 10.2 (unsupported).
|
|---|
| 22 | - liblist.c:
|
|---|
| 23 | o Enhanced script to provide the whole list of installed libraries
|
|---|
| 24 | in the correct order, without requiring parsing of dependencies.
|
|---|
| 25 | The functionality is achieved by invoking "liblist" with option '-m",
|
|---|
| 26 | i.e. - liblist -m [libpath] < libname.map
|
|---|
| 27 | where [libpath] is the path where libraries are placed
|
|---|
| 28 | (i.e. $G4LIB/$G4SYSTEM).
|
|---|
| 29 | - binmake.gmk:
|
|---|
| 30 | o Use "liblist -m [libpath]" to retrieve the list of libraries to link
|
|---|
| 31 | in case headers are installed in $G4INCLUDE, and granular libraries
|
|---|
| 32 | are used.

| 330 | o added guard for null stepTrial in FindNextChord().
|
|---|
| 331 | o correction from zero dChord in case of not-updated 'Unconstrained'
|
|---|
| 332 | step estimate (state).
|
|---|
| 333 | o Added instance variables to store number of calls and chord-trials.
|
|---|
| 334 | - G4EquationOfMotion:
|
|---|
| 335 | o made RightHandSide() inlined.
|
|---|
| 336 | o changed signature of Point in GetFieldValue(), now double[4].
|
|---|
| 337 | - Protection against division by 0 in
|
|---|
| 338 | G4MagIntegratorDriver::ComputeNewStepSize.
|
|---|
| 339 | - Fixes for unitialised variables in G4MagIntegratorStepper,
|
|---|
| 340 | G4FieldTrack, G4MagErrorStepper, G4Mag_SpinEqRhs, G4ExplicitEuler,
|
|---|
| 341 | and G4ImplicitEuler
|
|---|
| 342 | - Fixed memory leaks in G4ImplicitEuler and ExplicitEuler.
|
|---|
| 343 |
|
|---|
| 344 | o Materials:
|
|---|
| 345 | ---------
|
|---|
| 346 | - G4Material: removed constructors with chemical formula.
|
|---|
| 347 | - Added constant material properties to G4MaterialPropertiesTable.
|
|---|
| 348 | - G4IonisParamElm: fix in excitation energy interpolation.
|
|---|
| 349 | - G4IonisParamMat: added methods to Set/Find the mean excitation energy.
|
|---|
| 350 |
|
|---|
| 351 | o Particles:
|
|---|
| 352 | ---------
|
|---|
| 353 | - Updated mass width for resonance particles.
|
|---|
| 354 | - Fixed PDG codes for k0_star(1430), a0(1450) and f0(1370).
|
|---|
| 355 | - Made static inline method G4VDecayChannel::GetNoName() not inlined
|
|---|
| 356 | for porting on Windows DLLs.
|
|---|
| 357 |
|
|---|
| 358 | o Persistency:
|
|---|
| 359 | -----------
|
|---|
| 360 | - Implementation of abstract layer for persistency. Removed ODBMS
|
|---|
| 361 | specific implementation and setup. Now persistency library is part of
|
|---|
| 362 | the Geant4 kernel (see documentation on user manuals for details)
|
|---|
| 363 | o HepMC is not currently supported by CLHEP on Windows, so HepMC
|
|---|
| 364 | persistency is temporarly excluded from compilation on Windows.
|
|---|
| 365 |
|
|---|
| 366 | o Run, Intercoms and Interfaces
|
|---|
| 367 | -----------------------------
|
|---|
| 368 | - G4RunManager, G4RunMessenger:
|
|---|
| 369 | o Introduced "soft abortion", to allow event loop to abort after
|
|---|
| 370 | processing the current event. G4RunManager sets "eventAbortion"
|
|---|
| 371 | flag of G4Event if that particular event is aborted.
|
|---|
| 372 | o Introduced AbortEvent() method and corresponding UI command.
|
|---|
| 373 | - Introduced new G4Exception scheme: added G4ExceptionHandler class.
|
|---|
| 374 | - G4RunManager: introduced ResetNavigator() method needed in cases
|
|---|
| 375 | where a geometry has been modified between runs in order to properly
|
|---|
| 376 | re-initialize navigator's state.
|
|---|
| 377 | - Added two new pure virtual functions to G4VGraphicsScene:
|
|---|
| 378 | void AddThis(const G4VTrajectory&)
|
|---|
| 379 | void AddThis(const G4VHit&)
|
|---|
| 380 | - Fixed uninitialized data member and minor memory leak in G4UIcommand.
|
|---|
| 381 | - Fixed G4UIArrayStrings to work for "konsole" type termcap.
|
|---|
| 382 | - Patched access to public static data in G4VGlobalFastSimulationManager
|
|---|
| 383 | and G4VVisManager. Added static accessors to be used in the kernel to
|
|---|
| 384 | allow porting on Windows DLLs.
|
|---|
| 385 |
|
|---|
| 386 | o Tracking & Track:
|
|---|
| 387 | ----------------
|
|---|
| 388 | - Extensions of G4VTrajectory and introduction of curved trajectories
|
|---|
| 389 | o Added classes G4SmoothTrajectory and G4SmoothTrajectoryPoint.
|
|---|
| 390 | o Implemented default Show/DrawTrajectory() in G4VTrajectory.
|
|---|
| 391 | - G4SteppingManager:
|
|---|
| 392 | o implemented new ForceCondition flag StronglyForced.
|
|---|
| 393 | o fixed problem observed with optical processes.
|
|---|
| 394 | - G4TrackingManager
|
|---|
| 395 | o Re-implemented EventAborted() method to ensure this command
|
|---|
| 396 | works properly during stepping phase.
|
|---|
| 397 | o Set fpTrajectory pointer to zero when the trajectory is deleted.
|
|---|
| 398 | - Added accessors to auxiliary point vector, in both G4Step and
|
|---|
| 399 | G4ParticleChangeForTransport.
|
|---|
| 400 | - Set 'fUndefined' for the StepStatus in G4PostStepPoint.
|
|---|
| 401 | - Fixed initialisation of 'fCharge' in G4StepPoint constructor.
|
|---|
| 402 | - Patched access to public static data in G4VParticleChange.
|
|---|
| 403 | Added accessors to be used in the kernel to allow porting on
|
|---|
| 404 | Windows DLLs.
|
|---|
| 405 |
|
|---|
| 406 | o Transportation:
|
|---|
| 407 | --------------
|
|---|
| 408 | - G4Transportation: enable use of smooth (curved) trajectories.
|
|---|
| 409 | - Design iteration for standard scoring and class reorganisation
|
|---|
| 410 | o changed sampler concept: instead of separate samplers for
|
|---|
| 411 | all combinations of importance sampling, scoring, weight roulette
|
|---|
| 412 | for parallel and mass geometry, two samplers now are used
|
|---|
| 413 | for the mass and parallel geometry: G4MassGeometrySampler
|
|---|
| 414 | and G4ParallelGeometrySampler.
|
|---|
| 415 | o bug fixes in G4MassGeometrySampler, G4ParallelGeometrySampler,
|
|---|
| 416 | and G4MassGeometry.
|
|---|
| 417 | o moved G4CellStoreScorer, G4TrackLogger to digits+hits/detector.
|
|---|
| 418 |
|
|---|
| 419 | o Visualization:
|
|---|
| 420 | -------------
|
|---|
| 421 | - New implementation of HepRep driver (version 2).
|
|---|
| 422 | - Precision control of g4_XX.prim files are now generated by the
|
|---|
| 423 | DAWNFILE/DAWN-Network drivers, by use of a new variable for tuning
|
|---|
| 424 | precision G4DAWNFILE_PRECISION. Default precision is now set to
|
|---|
| 425 | 9 digits.
|
|---|
| 426 | - Fix (removal) of ambiguous G4VVisCommand::GetNewDoubleValue().
|
|---|
| 427 | - Added /vis/viewer/set/globalMarkerScale.
|
|---|
| 428 | - Improved algorithm of CompareForKernelVisit on OpenGL and OpenInventor.
|
|---|
| 429 | - OpenGL driver: fixes for WIN32 architecture at compilation level.
|
|---|
| 430 | Viewer still to be implemented.
|
|---|
| 431 | - Patched access to static data in G4VisCommandsSceneAdd.cc,
|
|---|
| 432 | G4VisManager.cc and G4FlavoredParallelWorldModel.cc to allow porting
|
|---|
| 433 | on Windows DLLs.
|
|---|
| 434 | - Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER for Windows
|
|---|
| 435 | and other small changes in OpenGL.
|
|---|
| 436 | - Added integer argument to /vis/scene/add/trajectories [drawing-mode].
|
|---|
| 437 | drawing-mode is passed to DrawTrajectory.
|
|---|
| 438 | - Fixed bug in G4VisManager wich lead to zero G4VModel pointer.
|
|---|
| 439 | - Improved handling of models.
|
|---|
| 440 | - Fixed division-by-zero cases in G4RayTracer.
|
|---|
| 441 | - VRML driver: bug fix for marker size.
|
|---|
| 442 | - Improved end of run behaviour for non-post-processing graphics systems.
|
|---|
| 443 |
|
|---|
| 444 | o g3tog4 tool:
|
|---|
| 445 | -----------
|
|---|
| 446 | - Fix in G4gsdvn G4gsposp to enable larger number of clone volumes
|
|---|
| 447 | - Fix for division defined in a mother with not yet defined parameters.
|
|---|
| 448 |
|
|---|
| 449 | o data
|
|---|
| 450 | ----
|
|---|
| 451 | - Updated data-sets for:
|
|---|
| 452 | o PhotonEvaporation: data-base now includes internal conversion
|
|---|
| 453 | coefficients.
|
|---|
| 454 | o RadiativeDecay.
|
|---|
| 455 |
|
|---|
| 456 | o Examples:
|
|---|
| 457 | --------
|
|---|
| 458 | - advanced:
|
|---|
| 459 | + Migration of most examples to use AIDA 3.X for histogramming.
|
|---|
| 460 | + Added "composite_calorimeter" example based on CMS test-beam setup.
|
|---|
| 461 | + Added "lAr_calorimeter" example based on ATLAS lAr-calorimeter
|
|---|
| 462 | test-beam setup.
|
|---|
| 463 | + underground_physics:
|
|---|
| 464 | o Updates to cope with new interface for G4scintillation process.
|
|---|
| 465 | o Updated geometry for better comparison with data. Corrected
|
|---|
| 466 | overlapping volumes and inefficient physics list.
|
|---|
| 467 | - extended
|
|---|
| 468 | o analysis
|
|---|
| 469 | + added "A01" example for usage of analysis and HepRep.
|
|---|
| 470 | o biasing
|
|---|
| 471 | + reduced examples to three:
|
|---|
| 472 | B01 - importance sampling and scoring. Importance values are
|
|---|
| 473 | defined according to the mass geometry. Scoring performed.
|
|---|
| 474 | B02 - uses a parallel geometry to define G4GeometryCell objects
|
|---|
| 475 | for scoring and importance sampling. In addition it customizes
|
|---|
| 476 | the scoring. In this example one scorer creates a histogram.
|
|---|
| 477 | It can be run through a Python script.
|
|---|
| 478 | B03 - importance sampling and scoring interactively through Python.
|
|---|
| 479 | o electromagnetic:
|
|---|
| 480 | + migrated histogramming to AIDA 3.X.
|
|---|
| 481 | + fixes to allow compilation in gcc-3.2 (TestEm1, TestEm2, TestEm3).
|
|---|
| 482 | o eventGenerator
|
|---|
| 483 | + enhanced interface to HepMC to use CLHEP module.
|
|---|
| 484 | o gdml:
|
|---|
| 485 | + fixed warnings on SUN and SUN linker problem.
|
|---|
| 486 | o persistency
|
|---|
| 487 | + introduced example (PersEx01) for persistency of calorimeter hits
|
|---|
| 488 | using ROOT-I/O.
|
|---|
| 489 | + removed old ODBMS-based examples.
|
|---|
| 490 | - novice
|
|---|
| 491 | o N06: updates according to new interface for G4Scintillation process.

| 519 | 1. Supported and Tested Platforms
|
|---|
| 520 | ---------------------------------
|
|---|
| 521 |
|
|---|
| 522 | o SUN Solaris 5.8, C++ 5.3 Patch 111685-07, C++ 5.4 Patch 111715-02.
|
|---|
| 523 | o Linux, gcc 2.95.2, gcc 3.2.
|
|---|
| 524 | This configuration was tested with the RedHat 7.2 and 7.3 distributions,
|
|---|
| 525 | versions of Geant4 have also been compiled successfully on other Linux
|
|---|
| 526 | distributions, like Debian or Suse.
|
|---|
| 527 | The default RedHat compiler gcc-2.96 ditributed in RedHat 7.X is NOT
|
|---|
| 528 | supported. It has been verified that it produces incorrect binaries,
|
|---|
| 529 | therefore is not reliable. See also note below.
|
|---|
| 530 | o Windows-2000/XP and CygWin Tools with: Visual C++ 6.0 Service Pack 5
|
|---|
| 531 |

| 539 | 2. AIDA and CLHEP
|
|---|
| 540 | -----------------
|
|---|
| 541 |
|
|---|
| 542 | Geant4 5.0 requires the installation of CLHEP.
|
|---|
| 543 |
|
|---|
| 544 | See CLHEP (http://cern.ch/clhep/INSTALLATION/clhep.html).
|
|---|
| 545 | Tests have been performed with CLHEP 1.8.0.0.
|
|---|
| 546 |
|
|---|
| 547 | Geant4 5.0 examples with histogramming cowork with AIDA 3.0 implementations.
|
|---|
| 548 | These include:
|
|---|
| 549 | - ANAPHE and components included therein
|
|---|
| 550 | (see: http://cern.ch/anaphe)
|
|---|
| 551 | - JAS (Java Analysis Studio)
|
|---|
| 552 | (see: http://jas.freehep.org)
|
|---|
| 553 | - Open Scientist
|
|---|
| 554 | (see: http://www.lal.in2p3.fr/OpenScientist)
|
|---|
| 555 |
|
|---|
| 556 | AIDA headers can be downloaded from: http://aida.freehep.org
|
|---|
| 557 |
|
|---|
| 558 |
|
|---|
| 559 | 3. The Standard Template Library
|
|---|
| 560 | --------------------------------
|
|---|
| 561 |
|
|---|
| 562 | Native versions of STL have been tested on the following platforms:
|
|---|
| 563 |
|
|---|
| 564 | Windows/2000, Linux, and SUN.
|
|---|
| 565 |
|
|---|
| 566 | NOTES:
|
|---|
| 567 |
|
|---|
| 568 | - Platform specific setup:
|
|---|
| 569 | o SUN: Native STL is required for ISO/ANSI setup.
|
|---|
| 570 | o Linux: Native STL is required (non ISO/ANSI setup for egcs compiler only).
|
|---|
| 571 | o Windows: Native STL and ISO/ANSI setup required (VC++ 6.0).
|
|---|
| 572 |
|
|---|
| 573 |
|
|---|
| 574 | 4. Compiler Specific Problems
|
|---|
| 575 | -----------------------------
|
|---|
| 576 |
|
|---|
| 577 | o Linux Red Hat 7.X, gcc-2.96.
|
|---|
| 578 |
|
|---|
| 579 | - The default compiler distributed by Red Hat since release 7.0 is
|
|---|
| 580 | NOT supported and not considered reliable for running a Geant4-based
|
|---|
| 581 | application. In more than one test case, binaries produced by gcc-2.96
|
|---|
| 582 | have shown incorrect behavior, either due to wrong order of
|
|---|
| 583 | initialisation of static data in memory or to bugs in the system
|
|---|
| 584 | iostream classes, problems which apparently have all been solved in
|
|---|
| 585 | more recent versions of the compiler (3.X series).
|
|---|
| 586 | For information, gcc-2.96 is a compiler that has never been
|
|---|
| 587 | officially released, nor supported by the GNU team itself and is not
|
|---|
| 588 | considered reliable by the authors (for more information, see also
|
|---|
| 589 | http://gcc.gnu.org/gcc-2.96.html).
|
|---|
| 590 |
|
|---|
| 591 |
|
|---|
| 592 | 5. Known Run-Time Problems and Limitations
|
|---|
| 593 | ------------------------------------------
|
|---|
| 594 |
|
|---|
| 595 | For a complete list of outstanding run-time problems and to submit any
|
|---|
| 596 | problem you may find running this version of Geant4, please refer to the
|
|---|
| 597 | Geant4 Problem Reporting System, available on the Web at this address:

|
|---|
| 600 |
|
|---|
| 601 |
|
|---|
| 602 | 6. Compilation Warnings
|
|---|
| 603 | -----------------------
|
|---|
| 604 |
|
|---|
| 605 | There are compilation warnings on some platforms. We do not believe
|
|---|
| 606 | that any will lead to incorrect run-time behaviour, but we are working
|
|---|
| 607 | on reducing them.
|
|---|
| 608 |
|
|---|
| 609 |
|
|---|
| 610 | 7. Known Run-Time Warnings
|
|---|
| 611 | --------------------------
|
|---|
| 612 |
|
|---|
| 613 | The following messages can be written to error output while tracking.
|
|---|
| 614 | We believe none give rise to incorrect behaviour.
|
|---|
| 615 |
|
|---|
| 616 | o G4PropagateInField: Warning: Particle is looping
|
|---|
| 617 | - tracking in field will be stopped.
|
|---|
| 618 | It has performed 10000 steps in Field while a maximum of 10000
|
|---|
| 619 | are allowed.
|
|---|
| 620 |
|
|---|
| 621 |
|
|---|
| 622 | 8. Items for migration of user code
|
|---|
| 623 | -----------------------------------
|
|---|
| 624 |
|
|---|
| 625 | o Compilation/installation of the 'g3tog4' module is now -optional- in
|
|---|
| 626 | release 5.0 and can be triggered only if G4USE_G3TOG4 is set during
|
|---|
| 627 | installation.
|
|---|
| 628 | o The new data sets for photon-evaporation and radioactive-decay are
|
|---|
| 629 | required, old data-sets are not compatible with this release.
|
|---|
| 630 | o Definition of the state IDs in G4ApplicationState have changed to
|
|---|
| 631 | prepend the "G4State_" prefix to the original state ID (i.e. "Idle"
|
|---|
| 632 | becomes "G4State_Idle", "Init" becomes "G4State_Init", and so on...).
|
|---|
| 633 | The user code (particularly, user defined messengers defining state
|
|---|
| 634 | dependent commands) will need to migrate to this new convention.
|
|---|
| 635 | o The interface for usage of the scintillation process has changed.
|
|---|
| 636 | Refer to the user's manual to learn about how to migrate the user code
|
|---|
| 637 | to use the new interface.
|
|---|
| 638 | o Interfaces for importance biasing and scoring have substantially changed
|
|---|
| 639 | and migration of the user code using these classes is required. Refer to
|
|---|
| 640 | the user's manual to learn about how to migrate the user code
|
|---|
| 641 | to use the new interfaces.
|
|---|
| 642 | o User defined solids will need to implement a new method:
|
|---|
| 643 | std::ostream& StreamInfo(std::ostream& os) const
|
|---|
| 644 | to dump solid's contents to an output stream.
|
|---|
| 645 | The method is now pure virtual in the base class G4VSolid.
|
|---|
| 646 | o The base class G4VTrajectory has been enhanced and new pure virtual
|
|---|
| 647 | functions have been introduced in G4VGraphicsScene:
|
|---|
| 648 | void AddThis(const G4VTrajectory&)
|
|---|
| 649 | void AddThis(const G4VHit&)
|
|---|
| 650 | User inherited classes require concrete implementations of the methods
|
|---|
| 651 | above, as well.
|
|---|
