|
|---|
| 75 | Fixes problem report #185.
|
|---|
| 76 | o Fixes in G4ReplicaNavigation for bug reports #253 and #254:

|---|
| 80 | the starting point is on boundary of replicas and direction is
|
|---|
| 81 | along boundary.
|
|---|
| 82 | o Enabled the use of different field managers for different parts
|
|---|
| 83 | of the detector. This first implementation allows a volume that
|
|---|
| 84 | has a field manager to override the global one.
|
|---|
| 85 | - Note: All field managers currently must refer to fields
|
|---|
| 86 | in global coordinates.
|
|---|
| 87 | - New ability: setting of the delta accuracy parameters differently
|
|---|
| 88 | in different volumes (even while maintaining the same
|
|---|
| 89 | field as the global one).
|
|---|
| 90 | o Added new parameter to G4PropagatorInField 'fEpsilonMin' which is
|
|---|
| 91 | the minimal relative accuracy for MF driving.

|---|
| 92 |
|
|---|
| 93 | o Global:
|
|---|
| 94 | ------

|---|
| 95 | - Added contructor to G4DataVector with additional argument
|
|---|
| 96 | for initialising values of collection.
|
|---|
| 97 | - Removed definition of cbrt() in globals.hh to allow ANSI compilation
|
|---|
| 98 | on Linux-g++ architecture with compiler gcc-2.95-2.
|
|---|
| 99 | - Defined 'str_size' as G4std::string::size_type and replaced usage of
|
|---|
| 100 | 'size_t' in G4String and G4SubString. Fixes problem report #40.
|
|---|
| 101 |
|
|---|
| 102 | o Graphics Representations:

|
|---|
| 111 | - Bug fix in BooleanProcessor to address problem report #153.
|
|---|
| 112 |
|
|---|

|
|---|
| 115 | - Migration to STL vector of the pre-compound and evaporation codes and
|
|---|
| 116 | removal of most warnings detected by Linux ANSI pedantic setup.
|
|---|
| 117 | - Management:
|
|---|
| 118 | o Fixes memory leak in G4InelasticInteraction: systematic search
|
|---|
| 119 | for leaks - energy scan 50MeV-10GeV.
|
|---|
| 120 | - High energy model:
|
|---|
| 121 | o Energy- OR Momentum- conservation, can be chosen by the user.
|
|---|
| 122 | o Added production of Evaporation particles.
|
|---|
| 123 | o Better description of experimental data, mainly in Strange
|
|---|
| 124 | Particle Production.
|
|---|
| 125 | o Cleared compilation warnings on Linux-g++.
|
|---|
| 126 | o Minor bug-fix in G4HEPionMinusInelastic.
|
|---|
| 127 | o Introduced temporary workaround in G4HEInelastic for high energy
|
|---|
| 128 | problem (number of particles created in one event larger than
|
|---|
| 129 | allocation).
|
|---|
| 130 | o Missing initialization of strangeness corrected, removing energy
|
|---|
| 131 | non-conservation in rare cases.
|
|---|
| 132 | - Generator models:
|
|---|
| 133 | o Upgrade of angular distributions and fission yields in pre-compound
|
|---|

| 139 | off Hydrogene. No recoil required.
|
|---|
| 140 | - Radiative-decay model:
|
|---|
| 141 | o Fixes to cowork with STL vector migration of 'geometry'.
|
|---|
| 142 | - Low energy neutron transport model:
|
|---|
| 143 | o New code revision: requires new set of data, G4NDL3.0 or later.
|
|---|
| 144 | o Includes also an upgrade of the doppler broadening.
|
|---|
| 145 | Allows for running on 0K data, and doing exact doppler broadening
|
|---|
| 146 | on the fly (according to the temperature specified in G4Material),
|
|---|
| 147 | with good performance up to about 5000K.
|
|---|
| 148 | o Bug fix in G4NeutronHPInelasticCompFS to get the correct Q-value
|
|---|
| 149 | for Lithium (the bug was introduced in recent development).
|
|---|
| 150 | - Utilities:

|
|---|
| 199 |
|
|---|
| 200 | o Visualization:
|
|---|
| 201 | -------------
|
|---|
| 202 | - Added two new commands:
|

|
|---|
| 227 | cloned mothers. G3toG4BuildTree() has been split in two methods
|
|---|
| 228 | G3toG4BuildLVTree() and G3toG4BuildPVTree(), the first creating
|
|---|
| 229 | logical volumes only, the second performing placements afterwards.
|
|---|

|
|---|
| 276 | 1. Supported and Tested Platforms
|
|---|
| 277 | ---------------------------------
|
|---|
| 278 |
|
|---|
| 279 | o SUN Solaris 5.6/5.7, C++ 4.2 Patch 104631-04, C++ 5.2 Patch 109508-03.
|
|---|
| 280 | o HP 10.20, aCC C++ B3910B A.01.23
|
|---|
| 281 | o Linux 2.2.17-7, gcc C++ egcs-2.91.66 (egcs 1.1.2), gcc 2.95-2.
|
|---|
| 282 | This configuration was tested with the RedHat 6.1 distribution, but
|
|---|
| 283 | versions of Geant4 have also been compiled successfully on more recent
|
|---|
| 284 | RedHat, Debian and Suse distributions.
|
|---|
| 285 | o NT 4.0 with Service Pack 4 or Windows-2000 and Cygnus Tools b20 with:
|
|---|
| 286 | Visual C++ 6.0 Service Pack 2
|
|---|
| 287 |
|
|---|
| 288 | Platforms also tested but giving rise to some problems - see below:
|
|---|
| 289 |
|
|---|
| 290 | o DEC V4.0, cxx C++ V6.1-027.
|
|---|
| 291 |
|
|---|
| 292 | Platforms configured but not tested and not supported:
|
|---|
| 293 | o SGI V6.5.5, CC 7.2.1 with ObjectSpace
|
|---|
| 294 | o AIX 4.3.2, xlC compiler with ObjectSpace
|
|---|
| 295 |
|
|---|
| 296 |
|
|---|
| 297 | 2. ANAPHE and CLHEP
|
|---|
| 298 | -------------------
|
|---|
| 299 |
|
|---|
| 300 | Geant4 3.2 requires the installation of CLHEP.
|
|---|
| 301 |
|
|---|
| 302 | See CLHEP (http://cern.ch/clhep/INSTALLATION/clhep.html).
|
|---|
| 303 | Tests have been performed with CLHEP 1.6.0.0.
|
|---|
| 304 |
|
|---|
| 305 | By default, the CLHEP installation scripts will activate ISO/ANSI C++ features
|
|---|
| 306 | if the compiler is capable. You need to explicitly disable CLHEP settings in
|
|---|
| 307 | case you wish non-ISO/ANSI setup on specific compilers.
|
|---|
| 308 |
|
|---|
| 309 | Geant4 3.2 coworks with ANAPHE 3.6.0 and components included therein:
|
|---|
| 310 | Objectivity 6.1
|
|---|
| 311 | ObjectSpace 2.1
|
|---|
| 312 | HepODBMS 0.3.2.9
|
|---|
| 313 | CLHEP 1.6.0.0
|
|---|
| 314 |
|
|---|
| 315 | For more information about ANAPHE, see: http://cern.ch/anaphe
|
|---|
| 316 |
|
|---|
| 317 |
|
|---|
| 318 | 3. The Standard Template Library
|
|---|
| 319 | --------------------------------
|
|---|
| 320 |
|
|---|
| 321 | The following versions of STL have been tested:
|
|---|
| 322 |
|
|---|
| 323 | ObjectSpace STL on SUN (CC 4.2).
|
|---|
| 324 |
|
|---|
| 325 | See ObjectSpace (http://www.objectspace.com).
|
|---|
| 326 |
|
|---|
| 327 | "Native" STL on: Windows/NT, Linux, HP, DEC and SUN (CC 5.2).
|
|---|
| 328 |
|
|---|
| 329 | This is selected at installation/compile time by the environment variable
|
|---|
| 330 | G4USE_OSPACE in the case of the former - see documentation.
|
|---|
| 331 |
|
|---|
| 332 | NOTES:
|
|---|
| 333 | - Be aware that by default, the installation scripts will expect to use
|
|---|
| 334 | the native STL implementation. You must set the G4USE_OSPACE variable
|
|---|
| 335 | in the environment in order to select the ObjectSpace implementation.
|
|---|
| 336 |
|
|---|
| 337 | - Platform specific setup:
|
|---|
| 338 | o DEC: ObjectSpace is required in non ISO/ANSI setup.
|
|---|
| 339 | Native STL is required for ISO/ANSI setup.
|
|---|

| 352 |
|
|---|
| 353 | Persistency in Geant4 3.2 release is tested on the following
|
|---|
| 354 | platforms:
|
|---|
| 355 |
|
|---|
| 356 | G4SYSTEM OS C++ compiler HepODBMS Objectivity
|
|---|
| 357 | --------- ----------- ------------ --------- -----------
|

| 358 | SUN-CC SunOS 5.6 CC 4.2 0.3.1.4 5.2.1
|
|---|
| 359 | SUN-CC5 SunOS 5.7 CC 5.2 0.3.2.10(*) 6.1.3 (*)

| 364 | option. See below.
|

|
|---|
| 369 | Known Problems
|
|---|
| 370 | --------------
|
|---|
| 371 |
|
|---|
| 372 | - There are several warning messages on some platforms during the
|
|---|
| 373 | installation of the libraries and the compilation of the examples.
|
|---|
| 374 | Most of them can be safely ignored. It is annoying but hard to get
|
|---|
| 375 | rid of them due to various reasons.
|
|---|
| 376 |
|
|---|
| 377 | - A warning message "Could not find naming root directory" appears at
|
|---|
| 378 | runtime of the persistency examples. It is generaged by
|
|---|
| 379 | HepDbApplication in HepODBMS. It can be ignored.
|
|---|
| 380 |
|
|---|
| 381 | - On Solaris7 (SUN-CC5), persistent header files has to be generated by
|
|---|
| 382 | ooddlx with "-noline" option to work around a bug in C++ compiler.
|
|---|
| 383 | This workaround applies not only to Geant4 Persistency category but
|
|---|
| 384 | also to HepODBMS, and the user defined ddl files as well. This
|
|---|
| 385 | option removes the "#line" directive of the file name and the line
|
|---|
| 386 | number of the original .ddl file. As a consequences, C++ compiler
|
|---|
| 387 | no longer "tells" the correct file name and the line number of the
|
|---|
| 388 | .ddl file if compiler error occurs. Try to identify the compiler
|
|---|
| 389 | error by first looking into the header file generated by ooddlx,
|
|---|
| 390 | and then locate the source of the problem by looking into the .ddl
|
|---|
| 391 | file. A patch to the compiler is expected from SUN.
|
|---|
| 392 |
|
|---|
| 393 |
|
|---|
| 394 | 5. Compiler Specific Problems
|
|---|
| 395 | -----------------------------
|
|---|
| 396 |
|
|---|
| 397 | o DEC V4.0, cxx C++ V6.1-027.
|
|---|
| 398 |
|
|---|
| 399 | - We have found cases of mis-compilation of min and max templates
|
|---|
| 400 | on DEC. We have traced those which cause serious malfunction
|
|---|
| 401 | but there is no guarantee that there are no other cases.
|
|---|
| 402 | Detailed inspection of assembler output suggests that this
|
|---|
| 403 | problem might not be confined to min and max. This has been
|
|---|
| 404 | reported to DEC/Compaq. We understand a new version 6.2 of the
|
|---|
| 405 | compiler is now available. However we cannot guarantee correct
|
|---|
| 406 | execution of Geant4 on DEC with the current version of the
|
|---|
| 407 | compiler.
|
|---|
| 408 | - A bug in cin.getline() system function causes an anomalous
|
|---|
| 409 | behavior when running in interactive-mode on DEC-cxx 6.1 in
|
|---|
| 410 | ISO/ANSI mode. We tested the bug has been fixed in more recent
|
|---|
| 411 | versions of the compiler.
|
|---|
| 412 |
|
|---|
| 413 |
|
|---|
| 414 | 6. Known Run-Time Problems and Limitations
|
|---|
| 415 | ------------------------------------------
|
|---|
| 416 |
|
|---|
| 417 | For a complete list of outstanding run-time problems and to submit any
|
|---|
| 418 | problem you may find running this version of Geant4, please refer to the
|
|---|
| 419 | Geant4 Problem Reporting System, available on the Web at this address:

|
|---|
| 422 |
|
|---|
| 423 |
|
|---|
| 424 | 7. Compilation Warnings
|
|---|
| 425 | -----------------------
|
|---|
| 426 |
|
|---|
| 427 | There are compilation warnings on some platforms. We do not believe
|
|---|
| 428 | that any will lead to incorrect run-time behaviour, but we are working
|
|---|
| 429 | on reducing them.
|
|---|
| 430 |
|
|---|
| 431 |
|
|---|
| 432 | 8. Known Run-Time Warnings
|
|---|
| 433 | --------------------------
|
|---|
| 434 |
|
|---|
| 435 | The following messages can be written to error output while tracking. We
|
|---|
| 436 | believe none give rise to incorrect behaviour.
|
|---|
| 437 |
|
|---|
| 438 | o G4PropagateInField: Warning: Particle is looping
|
|---|
| 439 | - tracking in field will be stopped.
|
|---|
| 440 | It has performed 10000 steps in Field while a maximum of 10000
|
|---|
| 441 | are allowed.
